       FIGS. 2 and 7  describe a preferred embodiment of a molding device  70 . The molding device  70  includes a hydraulic actuator  1  where the power end is coupled to a die holder  5  for moving and positioning such die holder  5 , two steel rods  2 A and  2 B for guiding and supporting the hydraulic actuator  1 , which are mounted on a hydraulic actuator sliding fixture  3 , and such hydraulic actuator sliding fixture  3  is coupled to two air cylinders  4 A and  4 B for moving the hydraulic actuator  1  horizontally to a predetermined position. Rails  23 A and  23 B are adapted to the air cylinders for support, alignment, and sliding surfaces for the hydraulic actuator sliding fixtures  3 . The die holder  5  is adapted to hold a die set comprised of a receiving die member  9 , a thermal isolation die member  10 , and mold die member  11 . Said die members are cooperatively coupled for a distribution of a chilled thermosetting polymer to flow under pressure to the heated section of the mold die member  11  and eventually injected on a substrate located opposite the opening of the mold die member  11 . In operation, the molding device  70  molds at least one three-dimensional body of silicone onto a garment or article of clothing  57  of  FIG. 31 . Commercially available silicone materials may be obtained from General Electric, Silicone Products Division, Waterford, N.Y.  
      More generally, the molding device  70  may be used to mold at least one three-dimensional body of a thermosetting polymer including but not limited to silicone, urethane, or nitrile rubber onto a substrate including but not limited to cloth, paper, cardboard, wood, leather, wire mesh, sponge or foam rubber.  
      More generally still, the molding device  70  may be used to mold a plurality of three-dimensional bodies of a plurality of types of thermosetting polymers including but not limited to silicone, urethane or nitrile rubber onto a substrate including but not limited to cloth, paper, wood, leather, wire mesh, cardboard, sponge or foam rubber. One of the limiting factors is the curing profile of different materials, which may vary and prevent the use of diverse materials in the same operation under the same operating conditions.  
      The hydraulic actuator  1  controllably moves the die set  75  into and out of engagement with the garment  57  under the control of the control system  90 . The hydraulic actuator  1  may be comprised of any number of conventional actuators including, but not limited to, pneumatic, hydraulic or electromechanical actuators. The movement of the hydraulic actuator  1  may be controlled using a combination of any number of conventional feedback control sensors and algorithms such as, for example, proportional-integral-differential. In a preferred embodiment, the actuator  1  is a hydraulic actuator, including pressure release and pressure sensors to stop at a predetermined position to prevent damage to the article of clothing  57  during engagement with the die set  75 . In this manner, delicate articles of clothing  57  are not damaged during engagement with the die set  75 . In a particularly preferred embodiment, the die set  75  is positioned within an air gap  50  from making contact with the article of clothing  57 . Alternatively, and more generally, the preferred range of air gap will vary as a function of the hot gas created by the thermosetting polymers undergoing an increase in temperature as the chilled polymer is being exposed to the hot peripheral surfaces of the mold die member  11 .  
      During exposure of the die set  75  with the article of clothing  57 , the die set  75  receives at least one supply of silicone resin from the silicone resin supply system  80 , injects at least one molding of silicone onto the article of clothing  57 , thermally raises the temperature of the chilled thermosetting polymer on contact with the heated mold die member  11 , and disengages from the article of clothing  57  under the predetermined settings of the control system  90 . The die set  75  may be comprised of any number of conventional die sets for injecting molding of thermosetting polymers onto substrates, modified in accordance with the teachings of the present disclosure.  
      In a preferred embodiment, as illustrated in  FIGS. 29, 30 ,  31  and  35 , the die set  75  is engaged to inject a molding of a thermosetting with the article of clothing  90 , the receiving die member  9  receives at least one supply of silicone resin from the silicone resin supply system  80  and transmits it to mold die member  11 . The temperature of the receiving die member  9  is maintained to the same low temperature of the chilled thermosetting polymer. The thermal isolation die member  10  is intentionally coupled between the heated mold die member  11  and the chilled receiving die member  9  to prevent the heat in mold die member  11  from transferring to receiving die member  9  and to prevent premature curing of the thermosetting polymer. The die members  9 ,  10  and  11  of the die set  75  are coupled intimately by reasonably rigid pins  40 A and  40 B, and fasteners to maintain the alignment of the members respectively within the die set  75  in all aspects and to prevent the members from shifting relatively to one another as such shifting negatively affects the distribution and heats the thermosetting polymer. The mold die member  11  receives the distribution of at least one supply of chilled silicone resin, which is heated upon contact with the peripheral surfaces of the member  11 , whereas the member  11  shapes the molding with at least one three-dimensional body of silicone, and injects onto the garment  57 . Such silicone resins may be commercially available from General Electric, Silicone Products Division, Waterford, N.Y.  
      Alternatively, during engagement of the die set  75  with the article of clothing  57 , the receiving die member  9  may receive at least one supply of a thermosetting polymer resin from the silicone resin supply system  80 , and transmit it to the mold die member  11  for molding.  
      Alternatively, and more generally, during engagement of die set  75  with the article of clothing  57 , the receiving die member  9  may receive supplies of a plurality of different types of thermosetting polymer resins such as silicone, urethane or nitrile rubber from the silicone resin supply system  80  and transmit it to the mold die member  11  for molding. In this manner, thermosetting polymers having similar time and temperature curing profiles may be simultaneously molded onto a substrate.  
      The guide members  40 A and  40 B and the fasteners  39 A,  39 B,  39 C and  39 D intimately couple rigidly the receiving die member  9 , the thermal isolation member  10  and the mold die member  11  to the die holder  5 . As illustrated in  FIGS. 30 and 31 , during engagement of the die set  75  with the garment  57 , the members  90 A and  90 B guide the die set  75  in position and permit the die members  9 ,  10  and  11  to cooperatively interact thereby permitting the passage of silicone from the removable injection nozzles  41 A,  41 B,  41 C and  41 D to deliver the silicone  45 ,  46 ,  47  and  48  to the mold die member  11 . This arrangement preserves the thermal integrity between the chilled silicone and the heated mold die member  11  and to prevent premature curing of the silicone prior to the desired delivery, namely the injection of the molding onto the substrate. The thermal isolation die member  10  thermally isolates the receiving die member  9  from the mold die member  11 . In this manner, a single layer of a thermal isolation die member  10  is inserted between the receiving die member  9  and the mold die member  11  as disclosed to integrally minimize the heat transfer between all members of the die set  75  during operation of the molding device  70 . In one of the preferred embodiments, a plurality of layers of such thermal isolation die members  10  may be used to enhance the integrity of the heat transfer. The control of the heat transfer is further enhanced by adaptively connecting a temperature sensor, namely a thermocouple  38 , as shown by  FIG. 29 , to the mold die member  11  and connecting such thermocouple  38  to the PLC  13  to adjust and turn on and off the heat input to the mold die member  11  as required by the teachings of this disclosure. Furthermore, the chilled temperature of the silicone and any of the thermosetting polymers is maintained and controlled by the cooling element as shown by the input and output, which is adapted to the receiving die member  9 .  
      Alternatively, an additional thermocouple  38  is adapted to the receiving die member  9  to determine the integrity of the heat transfer barrier and to prevent immature curing of the thermosetting polymer.  
      Furthermore,  FIG. 31  illustrates an embodiment of the flow passages for the silicone distribution within the mold die member  11 . The flow passages are formed in a single body using investment casting and CNC machining. Accordingly, the receiving die member  9  may receive at least one supply of a thermosetting polymer such as silicone, nitrile rubber or urethane by a transmission to the injection nozzle  41 . The output end of the injection nozzle  41  is adaptively connected to the mold die member  11  and internally inserted through the receiving die member  9  and the thermal isolation die member  10 . The input end of the injection nozzle  41  is connected to flexible supply line  42  of the silicone supply conduit system  85 . Alternatively, the mold die member  11  may substantially simultaneously receive supplies of a plurality of different types of thermosetting polymers for injection by adapting a plurality of the injection nozzles  41 A,  41 B,  41 C and  41 D to the receiving die member  9  such as silicone, urethane or nitrile rubber. In this embodiment, thermosetting polymers having similar time and temperature curing profiles may be simultaneously molded onto substrates.  
      The silicone resin inlet passages are contained within the body of the mold die member  11 . The silicone resin inlet passages are defined by injection nozzled tips  52 A,  52 B,  52 C, and  52 D positioned in one or more sides of the body of the mold die member  11  that extend sufficiently to raise the temperature of the thermosetting polymer by initial contact with the heated surface of the mold cavities  51 . The silicone resin inlet passages are preferably positioned substantially normal to the direction of the silicone resin outlet passages. The cross-sectional shape of the silicone resin inlet passages is preferably substantially circular.  
      The cross-sectional areas of the silicone inlet passages may range, for example, from about 0.010 to 10 square inches for typical silicone materials to provide improved flow characteristics. In a preferred embodiment, the cross-sectional areas of the silicone resin inlet passages range from about 0.100 to 1 square inches in order to provide optimum flow characteristics for typical silicone materials. The preferred physical characteristics will differ depending upon the types of thermosetting polymers employed.  
      The silicone inlet passages and the silicone resin outlet passages may be formed in the mold die member  11  using any number of conventional fabrication processes. In a preferred embodiment, the silicone resin inlet passages and silicone resin outlet passages are formed by CNC machining.  
      The cooling element controllably maintains the operating temperature of the receiving die member  9  within a predetermined range of temperatures. In a preferred embodiment, for typical grades of silicone, the cooling element maintains the operating temperature of the receiving die member  9  between approximately 45° and 60° F. For typical grades of silicone resins, this preferred range of operating temperatures provides a silicone material having a paste-like quality that in turn minimizes unwanted flow and dripping of the silicone material within the die set  75 . The preferred operating temperature ranges will differ depending upon the types of thermosetting polymers employed.  
      In a preferred embodiment, illustrated by  FIG. 29 , the cooling element is a fluid passage located within the body of the receiving die member  9  that conveys a cooling fluid such as chilled water through the body of the receiving die member to maintain the operating temperature of the thermosetting polymer at the desired range. In a preferred embodiment, the molding device  70  further includes a water cooling device, namely a chiller  14 , which provides a controlled supply of water, or other cooling fluid, to flow through the cooling element. In the preferred embodiment, the output signal from temperature sensor  38 , namely a thermocouple, is then utilized by the control system  90  to provide feedback control of the operating temperature of the receiving die member  9  and the mold die member  11  using a predetermined control algorithm.  
      The fluid passage of the cooling element may be formed on the body of the receiving die member  9  by brazing a thermally conductive fluid conduit onto a surface of the receiving die member  9 . In the preferred embodiment, the fluid passage of the cooling element is formed in the body of the receiving die member  9  by machining channels of continuous passage to circulate the cooling fluid in and out of the receiving die member  9 .  
      The cross-sectional areas of the silicone resin distribution passages may range, for example, from about 0.010 to 10 square inches for typical silicone materials to provide improved flow characteristics. In a preferred embodiment, the cross-sectional areas of the silicone resin inlet passages range from about 0.100 to 1 square inches in order to provide optimum flow characteristics for typical silicone materials. The preferred physical characteristics will differ depending upon the types of thermosetting polymers employed.  
      The silicone resin outlet passages are contained within the body of the mold die member  11 . The silicone resin outlet passages are defined by openings positioned inwardly of the bottom face of the mold die member  11  and the shape of the openings must be sufficient to deliver the desired molding according to the disclosure.  
      The cross-sectional areas of the silicone resin outlet passages may range from about 0.010 to 10 square inches for typical silicone materials to provide improved flow characteristics. In a preferred embodiment, the cross-sectional areas of the silicone resin outlet passages range from about 0.100 to 1 square inches in order to provide optimum flow characteristics for typical silicone materials. The preferred physical characteristics will differ depending upon the types of thermosetting polymers employed.  
      In the preferred embodiment, that transmission of silicone resin from the silicone resin supply lines  42 ,  43 ,  44  and  49  to the corresponding silicone resin outlet passages of the mold die member  11  is facilitated by the injection nozzles  41 A,  41 B,  41 C and  41 D. As illustrated in  FIG. 31 , the injection nozzles  41 A,  41 B,  41 C and  41 D extend through the die holder  5  to the outlet passages of the die cavities  51  of the mold die member  5 . In operation, during engagement of the die set  75  with the garment  57 , the injection nozzles  41 A,  41 B,  41 C and  41 D cooperatively interact with complementary shaped silicone resin inlet passages in a top face of the mold die member  11 . The silicone resin outlet passages may be formed, as integral parts of the mold die member  11 , using conventional machining processes. In the preferred embodiment, the injection nozzles  41 A,  41 B,  41 C and  41 D and nozzle tips  52 A,  52 B,  52 C and  52 D are separable from die set  75  and comprised of a durable material such as tempered steel or stainless steel. In this arrangement, heat transfer from the mold die member  11 , as the member is intimately coupled within the die set  75 , is conservatively limited by positioning the isolation thermal member between such member and the receiving die member  9 . Additionally, the nozzle tips  52 A,  52 B,  52 C and  52 D can be replaced without disturbing other members of the die set and effectively improve the efficiency of the operations with less downtime for repair or maintenance. Furthermore, the durable materials, namely machinable steel that can be shaped by machines, permit the use of higher pressure to deliver the injection of the thermosetting polymer for better efficiency than low strength material such as copper or ceramic.  
      In the preferred embodiment, as illustrated in  FIG. 31 , the mold die member  11  includes a plurality of injection nozzles  41 A,  41 B,  41 C and  41 D, a plurality of corresponding mold cavities  51 A,  51 B,  51 C and  51 D, heaters  37 A and  37 B, and a temperature sensor  38 . The injection nozzles  41 A,  41 B,  41 C and  41 D of the mold die member  11  receive silicone resin from the corresponding silicone resin supply lines  42 ,  43 ,  44  and  49  of the silicone resin conduit system  85 . The injection nozzles  41 A,  41 B,  41 C and  41 D transmit silicone resin to corresponding mold cavities  51 A,  51 B,  51 C and  51 D. The heaters  37 A and  37 B provide heat to cure the silicone resin bodies as they are formed by the mold cavities of the mold die member  11  and as they come into contact with the peripheral surfaces of the cavities  51 A,  51 B,  51 C and  51 D. The temperature sensor  38  permits feedback control of the operating temperature range of the mold die member  11 . The injection nozzles  41 A,  41 B,  41 C and  41 D positions the tangential plane of the lower face of the nozzle tips  52 A,  52 B,  52 C and  52 D substantially coincident with the tangential plane of the upper inner surface of the mold cavities  51 A,  51 B,  51 C and  51 D of the mold die member  11 . After the completion of the injection, the top surface of the molded three-dimensional body of silicone is substantially smooth.  
      In the preferred embodiment, the mold cavities  51 A,  51 B,  51 C and  51 D of the mold die member  11  are formed by first forming passages adapted to receive and intimately couple with the injection nozzles  41 A,  41 B,  41 C and  41 D, CNC machining the mold cavities  51 A,  51 B,  51 C and  51 D and then inserting the injection nozzles  41 A,  41 B,  41 C and  41 D. In this manner, the tangential planes of the upper inner surfaces of the mold cavities  51 A,  51 B,  51 C and  51 D are made substantially exactly coincident with the tangential lower planes of the lower faces of the nozzle tips  52 A,  52 B,  52 C and  52 D.  
      During operation of the molding device  70 , the mold cavities  51 A,  51 B,  51 C and  51 D receive the silicone resin supply from the corresponding silicone injection nozzles  41 A,  41 B,  41 C and  41 D. The silicone resin fills the cavities  51 A,  51 B,  51 C and  51 D and forms the three-dimensional bodies of silicone resin on the top surface of the article of clothing  57 . The heaters  37 A and  37 B raise the silicone resin bodies formed by the mold cavities  51 A,  51 B,  51 C and  51 D as the silicone comes into contact with the peripheral surface of the mold cavities  51 A,  51 B,  51 C and  51 D. Because of the pressure used in the injection, the heated silicone resin molding will create an adhesion to surface of the article of clothing  57  as it comes in contact with such surface and the adhesion is intensified as the molding solidifies.  
      The mold die member  11  may include any number of mold cavities  51  depending upon the intricacy of the particular graphical design to be affixed to the article of clothing  57 . Furthermore, one or more of the silicone bodies formed may be comprised of different colors of silicone. The surface texture of the silicone bodies may be smooth or textured. The texture of the silicone body may be provided by a corresponding surface texture of the inner surface of the mold cavity  51 .  
      The heaters  37 A and  37 B may comprise any number of conventional heating elements such as electrical heaters. In a preferred embodiment, the heaters  37 A and  37 B are bendable heating elements which are structurally cylindrical and commercially known as “cal rod”. A plurality of such cal rod heaters are used and are positioned substantially evenly between and among the mold cavities  51  of the mold die member  11  for an evenly distribution of thermal energy within the mold die member  11 .  
      The temperature sensor  38  may comprise any number of conventional temperature sensors such as thermocouple or thermistor. In a preferred embodiment, the temperature sensor  38  is a thermocouple. The temperature sensor  38  generates a signal representative of an operating temperature of the mold die member  11  that is processed by the control system  90  to control the operation of the heaters  37 A and  37 B to maintain the operating temperature of the mold die member  11  within a predetermined range of temperatures. The predetermined range of the operating temperatures of the mold die member  11 , for typical types and grades of silicone resin, may range from approximately 150° to 500° F.  
      The predetermined range of operating temperatures of the mold die member  11 , for typical types and grades of silicone resins, ranges from about 150° to 300° F. The desired range of operating temperatures will differ depending upon the types of thermosetting polymers employed.  
      In an alternative preferred embodiment of the mold die member  11 , raised borders are provided about a periphery of each of the mold cavities  51 A,  51 B,  51 C and  51 D that extend outward from the bottom surface of the mold die member  11 . The raised borders minimize splattering of the hot silicone molding and define in part the shape of the graphic, thereby optimizing the injection of the silicone molding to the article of clothing  57 . The thickness and height of the raised borders may range from about 0.25 to 1.5 millimeters 0.02 to 9 millimeters respectively. The preferred thickness and height of the raised borders range from about 0.50 to 0.75 millimeters and 0.50 to 6 millimeters respectively. The preferred range of the thickness and height of the raised borders will vary as a function of the size and configuration of the mold cavities  51 A,  51 B,  51 C and  51 D and the type of thermosetting polymers.  
      The mold die member  11  includes a plurality of flow passages and heaters  37 A and  37 B. The flow passages are continuously coupled and they extend from the inlet passages at the nozzle tips  52 A,  52 B,  52 C and  52 D of the injection nozzles  41 A,  41 B,  41 C and  41 D to the cavities  51  of the mold die member  11 . The adaptation of the injection nozzles  41 A,  41 B,  41 C and  41 D to the flow passages for conveying silicone resin from the silicone resin supply lines  42 ,  43 ,  44  and  49  to the mold die member  11  facilitates the conservation of the heat transfer integrity between the chilled section and the heated section of the die set  75  and minimizes the premature exposure of the thermosetting polymer. The heaters  37 A and  37 B provide thermal energy and may comprise any number of conventional heating elements such as electrical heaters or cal rods. In a particularly preferred embodiment, the heaters  37 A and  37 B are distributed among and between the flow passages in order to provide a substantially even distribution of thermal energy. The operating temperature of the mold die member  11  is preferably controlled by the control system  90 , which monitors the temperature of the mold using the temperature sensor  38 . The control system  90  then preferably controls the operation of the heaters  37 A and  37 B to maintain the operating temperature of the mold die member  11  within a predetermined range of temperatures.  
      In a preferred embodiment, as illustrated in  FIGS. 6, 33  and  34 , the back plate  6 A or  6 B includes a back plate body adaptively mounted on a sliding fixture  7 A or  7 B, sliding track members  8 A,  8 B,  8 C and  8 D, air cylinders  24 A and  24 B, sliding blocks  25 A,  25 B,  25 C and  25 D, and a supporting member  34 . The back plate  6 A or  6 B supports and positions the article of clothing  57 , or other substrate, during engagement with the die set  75  of the molding device  70 . In particular, during engagement of the die set  75  with the top surface of the article of clothing  57 , the die set  75  is positioned as such the bottom surface of the mold die member  11  and the top surface of the article of clothing  57  is separated by an air gap sufficient to permit the hot gas from the formation of the thermosetting polymer molding.  
      The back plate  6 A or  6 B is preferably a substantially planar upper surface that directly supports the article of clothing  57 . The back plate  6 A or  6 B preferably includes at least one redundant controlling member, namely sliding blocks  25 A,  25 B,  25 C and  25 D, and controllable moving device such as air cylinders  24 A and  24 B to properly move and position the article of clothing  57  in coordination and relative to the die set  75 .  
      In one of the embodiments, illustrated in  FIG. 34 , the back plate  6 A or  6 B is designed to support and position a T-shirt  57 . The T-shirt  57  fits over the back plate  6 A or  6 B with a part of the surface of the back plates  6 A and  6 B is used to provide reference surfaces to provide proper positioning of the T-shirt  57  relative to the die set  75 . For different types of substrates, different reference surfaces will be provided.  
      As illustrated in drawings  FIGS. 6 and 34 , the back plate  6 A or  6 B is moved into and out of position below and opposite to the die set  75  by the power of the air cylinders  24 A and  24 B which are programmably controlled by the PLC  13 . The back plate  6 A or  6 B operates in coordination and sequentially with the die set  75  by a predetermined algorithm, which is programmed in the PLC  13 . The PLC  13  controls and coordinates the motion of the hydraulic actuator  1  to safely position the die set  75  and activate the injection to form the graphic design onto the substrate. The hydraulic actuator  1  lowers the die set  75  as the back plate  6 A or  6 B with the loaded substrate  57  move into position opposite of the die set  75  to begin the injection of the thermosetting polymer. The hydraulic actuator  1  is set by the algorithm to stop within the air gap without the bottom surface of the mold die member  11  touching the top surface of the substrate  57 . The hydraulic actuator  1  retracts the die set  75  after the injection is complete. The dies set  75  is conjunctively connected to the hydraulic actuator  1  by connecting the top of the die set  75 , namely the top of the receiving die member  9 , to the bottom end of the die holder  5  and connecting the power shaft of the hydraulic actuator  1  to the top end of the die holder  5 . In this manner, loading and unloading of substrates  57  onto and off of the platen are facilitated by permitting the operator to operate outside of the strike zone of the die set  75 . This preferred embodiment provides added safety by eliminating the possibility of injury to the operator caused by mistakenly engaging the die set  75  while loading and unloading of substrates  57  onto and off of the back plate  6 A or  6 B.  
      The support member  34  supports the dynamic loads and the static load of the assembly of the back plates  6 A and  6 B and during the injection of the thermosetting polymer. The support member  34  may comprise any number of structural support members capable of maintaining the structural integrity and reasonably rigid support during the molding process. Transition members support the back plates  6 A and  6 B and cooperatively connect the back plates  6 A and  6 B to the sliding fixtures  7 A and  7 B. This arrangement permits the back plates  6 A and  6 B to be controllably moved by the air cylinders  24 A and  24 B and guided by the sliding track members  8 A,  8 B,  8 C and  8 D. The sliding track members  8 A,  8 B,  8 C and  8 D may comprise any number of conventional rolling members capable of rigid support during the molding process. The sliding track members  8 A,  8 B,  8 C and  8 D provide directional guidance to the back plates  6 A and  6 B during the loading and unloading process. The sliding track members  8 A,  8 B,  8 C and  8 D also facilitate the positioning of the back plates  6 A and  6 B below and opposite the die set  75 . In the preferred embodiment, the sliding track members  8 A,  8 B,  8 C and  8 D include sliding blocks  25 A,  25 B,  25 C and  25 D that provide set points related to the air cylinders for controlling the travel and positions of the back plates  6 A and  6 B below and opposite the die set  75 .  
      Referring to drawing  FIGS. 31, 33  and  34 , during engagement of the die set  75  with the article of clothing  57 , the hydraulic actuator  1  moves the die set  75  toward the top surface of the article of clothing  57  that is supported and positioned by the back plate  6 A or  6 B. The hydraulic actuator  1  continues to move the die set  75  until the die set  75  fully stops within the predetermined air gap of the top surface of the article of clothing  57 .  
      The movement of the die set  75  into engagement with the top surface of the article of clothing  57  by the hydraulic actuator  1  is controlled by the control system  90  using any number of conventional control algorithms and subjected to any number of conventional position sensors. Alternatively, the movement of the die set  75  into engagement is controlled by the control system  90  using position sensors, pressure sensors, speed sensors, position and pressure sensors, position and speed sensors, pressure and speed sensors, or position, pressure and speed sensors. Furthermore, the movement of the die set  75  into engagement with the top surface of the article of clothing  57  is controlled by the control system  90  by monitoring at least a pressure sensor that generates a signal representative of a contact pressure of the die set  75  with a reference surface representing the predetermined air gap  50  formed by the bottom surface of the mold die member  11  and the opposite surface of the article of clothing  57 . In this manner, the article of clothing  57  will not be damaged by the die set  75  during engagement. The preferred air will differ depending upon the types of substrates and thermosetting polymers employed.  
      Upon engaging the die set  75  within the predetermined air gap at the top surface of the article of clothing  57 , the silicone resin supply system  80  injects a controlled predetermined amount of silicone resin into each of the mold cavities  51  of the heated mold die member  11 . The controlled amount of silicone resin is received by the injection nozzle  41  mounted intimately to the cooled receiving die member  9  and passes through the thermal isolation die member  10  to the corresponding injection nozzle tip  52 . The injection nozzle tip  52  distributes the silicone resin to the corresponding mold cavities  51  of the heated mold die member  11 . The silicone resin then fills the corresponding mold cavities  51  of the mold die member  11  to form at least one three-dimensional body of silicone resin on the article of clothing  57 .  
      More generally, upon full engagement of the die set within the predetermined air gap at the top surface of the article of clothing  57 , the silicone resin supply system  80  injects a controlled predetermined amount of a plurality of different types of thermosetting polymer resins into the mold cavities  51  of the heated mold die member  11 . The controlled amounts of the different types of thermosetting polymer resins are received by the injection nozzles, which are intimately mounted to the receiving die member  9 , and internally connected through the thermal isolation die member  10  to the heated mold die member  11 . The nozzle injection tip  52 A,  52 B,  52 C and  52 D distributes the thermosetting polymer resins via the distribution channels to the corresponding mold cavities  51  of the heated mold die member  11 . The thermosetting polymer resins then fill the corresponding mold cavities  51  of the mold die member  11  to form a plurality of three-dimensional bodies of a plurality of types of thermosetting polymer resins on the substrate  57 . In this manner, thermosetting polymers having similar time and temperature curing profiles may be simultaneously molded onto substrates.  
      For typical types and grades of silicone, the operating temperature of the cooled receiving die member  9  may range from about 50° to 65° F. In a preferred embodiment, the operating temperature of the receiving die member  9  is maintained from about 55° to 60° F. Alternatively, for different thermosetting polymers, the preferred operating temperatures may differ.  
      The volumetric flow rate and pressure of the injection of silicone resin into the mold cavities  51  of the heated mold die member  11  is preferably controlled to effectively produce the desired graphic design on the substrate  57 . For typical clothing materials and grades of silicone resin, the volumetric flow rate and pressure of the silicone resin injection may range from about 0.33 to 0.50 in 3 /sec and about 200 to 800 psig. In a preferred embodiment, for typical clothing materials and grades of silicone resin, the volumetric flow rate and pressure of the silicone injection ranges from about 0.01 to 0.33 in 3 /sec and about 300 to 600 psig. Alternatively, the preferred flow rates and pressures will differ depending upon the specific types of substrates and thermosetting polymer resins employed.  
      The silicone resin initially will adhere to the top surface of the material of the article of clothing  57  and solidified as it cures. The three-dimensional body of silicone resin is cured by action of the heat transferred from the heated mold die member  11  as the silicone resin contacts the peripheral surfaces of the mold die member  11 . The amount of time required to cure the three-dimensional bodies of silicone resin depends upon the volume of the three-dimensional bodies of silicone resin and the material type in a well known manner. Alternatively, the curing time is incorporated into computing the time the die set  75  engages the substrate  57 .  
      Generally, the operating temperatures of the mold die member  11  may range from about 75° to 500° F. In a preferred embodiment, for typical types and grades of silicone, the operating temperatures of the mold die member  11  range from about 150° to 300° F. Alternatively, for different thermosetting polymers, the preferred operating temperatures will differ. The type of silicone used in the molding device  70  may comprise any number of commercially available silicone products such as GE LIM  3745 , GE LIM  6030 , GE LIM  6090 , GE LIM  6045 , GE LIM  6050  or GE LIM  6745 , which may be commercially available from the General Electric Company, Silicone Products Division in Waterford, N.Y.  
      Any thermosetting polymer may be used in the molding device  70  to form three-dimensional bodies of a thermosetting polymer on a substrate. Such thermosetting polymers include at least the following: silicone, nitrile rubber or urethane, and such substrates include at least the following: cloth, paper, cardboard, wood, leather, wire mesh, sponge, or foam rubber.  
      Once the three-dimensional bodies of silicone are delivered by injection on the positioned article of clothing  57 , the die set  75  is disengaged. Upon disengagement, the mold die member  11  retracts as the hydraulic actuator  1  moves vertically upward and the backplate  6 A or  6 B slides away to deposit the substrate  57  outside the strike zone of the molding device  70 . The thermal isolation die member  10  provides a thermal barrier to prevent silicone resin from curing within the injection nozzles  52 A,  52 B,  52 C and  52 D.  
      Accordingly, drawing  FIG. 35  illustrates the preferred embodiment with one or more flow control valves  54 A,  54 B,  54 C,  54 D or  54 E for controllably connecting the silicone resin flow passages, namely injection nozzles  41 A,  41 B,  41 C or  41 D to a silicone resin supply  21 A and  21 B, and a color mixer,  53 . Under this arrangement, the injection of silicone resin into the die set  75  may be precisely controlled and stopped by action of the flow control valve  54 . This in turn will allow the injection system to build up a predetermined pressure suitable to deliver a predetermined silicone shot to the die set  75 . The flow control valve  54 A,  54 B,  54 C,  54 D,  54 E or all the control valves include actuators which are connected to the PLC  13 , are controllably operated in coordination with the predetermined and programmable injection process algorithms.  
      Alternatively, the injection of a thermosetting polymer resin into the die set  75  may be precisely controlled and stopped by action of the flow control valve  54 , which is adapted to control the pressure and flow rate of the material. This in turn will allow the injection system to build up a predetermined pressure suitable to deliver a predetermined silicone shot to the die set  75 . The flow control valve  54 B,  54 C,  54 D,  54 E or all the control valves include actuators, which are connected to the PLC  13 , are controllably operated in coordination with a predetermined and programmable injection process algorithms.  
      Furthermore, in the preferred embodiment, as illustrated in drawing  FIGS. 1, 23 ,  24 ,  26  and  35 , the hydraulic activated injection valve  30 A,  30 B,  30 C,  30 D, or  30 E comprise a two-position valve, including a two-position valve element and an actuator, mounted within the body of the manifold  29  and controlled by the control system  90  and specifically by the PLC  13 . In a first position, the two-position injection valve  30  permits flow of silicone resin from a silicone resin supply system  80  to a corresponding one of the silicone injection pumps  26 A,  26 B,  26 C,  26 D or  26 E by drawing the corresponding piston below the inlet of the injection cylinder of the injection pump  26 A,  26 B,  26 C, or  26 D. In a second position, the two position injection valve  30  forces the silicone resin to flow out of the cylinder by applying a hydraulic flow to pressurize the injection piston  27 A,  27 B,  27 C,  27 D or  27 E and force the piston  27 A,  27 B,  27 C,  27 D or  27 E to move forward. The forward motion sequentially force the silicon shot through the opening of the control valve  54 A,  54 B,  54 C,  54 D or  54 E, which was previously closed. The silicone shot follows the injection lines  55 A,  55 B,  55 C,  55 D or  55 E to an adaptable connector  56 A,  56 B,  56 C,  56 D or  56 E connected to the corresponding injection nozzle  41 A,  41 B,  41 C or  41 D, and to the injection nozzle tip  52 A,  52 B,  52 C or  52 D accordingly connected to the distribution channels of the mold die cavity  51 . The size and the physical aspects of the silicone shot determines the draw of the piston  27 A,  27 B,  27 C,  27 D or  27 E. Furthermore, the larger the volumetric size of the silicone shot the longer is the draw of the piston  27 A,  27 B,  27 C,  27 D or  27 E if the diametrical cross section of the piston is fixed, a variation in the volume of the shot requires the draw of the piston to vary accordingly. The silicone pumps  22 A and  22 B provides a necessary hydraulic lift to deliver the silicone resin to the injection cylinder of the injection pump  26 A,  26 B,  26 C or  26 D. The cross-sectional areas of the various flow passages of the systemic elements of the silicone resin supply, namely the control valves, the injection pumps are preferably selected to prevent turbulent flow of the silicone resin, or the particular thermosetting polymer resin, in operation. Alternatively, the number of control valves, conduits, nozzles, nozzle tips and injection pumps varied according to the number of silicon resins necessary to produce a graphic design. The use of injection pumps  26 A,  26 B,  26 C,  26 D and  26 E allows the silicone shot to be delivered precisely for the predetermined amount without the silicone drip generally associated with other arrangements because the inherent accuracy of the metering mechanism of the injection pumps  26 A,  26 B,  26 C,  26 D and  26 E is well known and can be used to eliminate excess silicone material. This arrangement eliminates the need to use exhaust pump, vacuum source such as evacuated chamber, air blast to remove excess silicone from the die set  75  or the flow passage to the die set  75 .  
      The preferred embodiment includes a plurality of silicone resin supplies  21 A and  21 B or more. The plurality of silicone resin supplies  21 A and  21 B are preferably controllable to provide a predetermined amount a plurality of supplies of silicone resin to each of the molding devices  70 . In this manner, each of the molding devices  70  can mold a plurality of diverse types of thermosetting polymers and three-dimensional bodies onto substrates substantially simultaneously. Furthermore, the plurality of supplies of silicone resin supply system  80  is preferably provided with at least a plurality of colors of silicone resin. A color mixer  53  is used to provide a predetermined color to the predetermined polymer thermosetting by adding a color pigment to the thermosetting polymer from the silicone resin supplies  21 A and  21 B.

Alternatively, more generally, the desired volumetric size of the silicone conduit manifold  19  will vary as a function of the particular thermosetting polymer selected as well as the size and number of molding devices  70  and mold cavities  51  simultaneously in use. In an alternative preferred embodiment, the color pigment is omitted to be included in the silicone conduit manifold  19  and only uncolored polymer resin is produced. Consequently, the number of various colors and types of thermosetting polymers are represented the same. In this manner, each molding device can mold a plurality of three-dimensional silicone bodies having a plurality of colors onto a substrate. Alternatively, the silicone conduit manifold  19  may be adapted to mix and color any number of thermosetting polymer resins such as silicone, nitrile rubber or urethane.

Alternatively, more generally, the desired flow rates will vary as a function of particular thermosetting polymer selected and the constituent materials comprising the specific thermosetting polymer selected.

The pressure relief valve automatically releases material from the flow control assembly whenever the operating pressure exceeds a predetermined maximum as determined by a spring bias provided in the pressure relief valve. The exhaust valve controllably permits material to be exhausted from the flow control assembly under the control of the control system  90 . The control system  90  monitors the pressure sensor and flow sensor, and controllably operates the variable orifice and exhaust valve to maintain the operating pressure and flow rate of the flow control assembly within a predetermined range of values using conventional control algorithms for fluids.

The control system  90  monitors and controls the operation of the apparatus  60  and includes at least one more sensors and actuating devices. As illustrated in drawing  FIGS. 1 and 8 , in a preferred embodiment, the control system  90  includes a programmable general purpose computer or programmable PLC  13 , a keyboard, a touch screen monitor  12 , a modem, a local-area-network communication device, a wide-area-network communication device, the silicone resin pumps  22 A and  22 B, the water cooling devices (chiller)  14 , the molding device  70 , the heaters  37 A and  37 B, the hydraulic actuated injection valves, including at least  30 A,  30 B,  30 C,  30 D and  30 E, the silicone resin supply system  80 , the pressure sensors for the silicone resin supply system  80 , the temperature sensors, including at least one thermocouple  38 , the hydraulic actuator  1  for the molding device  70 , the flow sensors for the silicone resin supply system  80 , control switches  16 A and  16 B for the apparatus  60 , and redundant safety switches with laser connection for the apparatus  60 .

A break in the continuity of the laser light path will consequently discontinue the electrical flow as well as cutting off the supplying power to the molding device  70 . The control switches  16 A and  16 B are of conventional design and operation and protect the operator from physical injury by requiring the operator to press both switches during engagement of the die sets  75  of the molding devices  70 . The light curtains are of conventional design and construction and surround the molding devices  70  with a light barrier that, if broken, shuts down the molding devices  70  to protect the operator from injury.  
      Drawing  FIGS. 33-34  illustrate a preferred embodiment of the operation of the molding device  70 , namely an injection cycle. At an initial startup, a physical set-up of the molding device  70  is required. Generally, the set-up includes preparing and determining the pressure for the hydraulic actuator  1  for the molding device  75 , selecting, assembling and aligning the die set  75  for the molding device  70 , selecting and determining the proper silicone resin, or other thermosetting polymer resin, supplies  21  for the molding device  70  and the commercial order, and loading computer coded instructions and initializing the control system  90 .  
      After the initial sequence of the startup has been started, the following sequence will initiate cooling for all related fluidic containment system for the delivery of the silicon prior to contact with the heated mold die member  11 . The cooling sequence will preferably include the steps of selecting a predetermined range of operating temperatures, starting the chiller  14 , receiving the signal output from the thermal sensors, which strategically are located at the receiving die member  9 , the silicone conduit manifold  19  and the die holder  5 , and maintaining the predetermined temperature. For typical types and grades of silicone resins, the operating temperatures range from about 50° to 65° F. In a preferred embodiment, the operating temperature ranges from about 55° to 60° F. The preferred operating temperature range will vary as a function of the volume and particular type and grade of thermosetting polymer selected for use with the molding device  70 .  
      In the continuity of the start-up sequence, the PLC  13  continues to initiate heating for the mold die member  11 . The heating sequence will preferably include the steps of selecting a predetermined range of operating temperatures for the mold die member  11 , closing the heating circuit switches to allow the heaters  37 A and  37 B to generate heat, receiving output signal from the temperature sensor  38 , and maintaining the predetermined temperature. For typical types and grades of silicone resins, the operating temperature ranges from about 75° to 500° F. In a preferred embodiment, the operating temperature ranges from about 150° to 300° F. The preferred operating temperature range of the mold die member  11  will vary as a function of the number and volume of mold cavities  51 , and the particular type and grade of thermosetting polymer resin selected for use with the molding device  70 .  
      The order of execution of the start-up sequences to initiate the cooling and heating operations are simultaneous and alternatively it can be consecutively performed through the commands of the PLC  13  depending on the available power capacity and environmental circumstances. Considerations are given to prevent the operating temperature of the receiving die member  9  from fluctuation due to rising heat transfer from the mold die member  11 , which is conventionally known during start-up. These cooling and heating sequences do not affect the back plates  6 A and  6 B, which do not have a dedicated cooling and heating system as used in conventional devices.  
      Including in the operational steps are the system pressure checks for the air cylinders  4 A,  4 B,  24 A and  24 B, and the hydraulic activated injection valves  30 A,  30 B,  30 C,  30 D and  30 E.  
      The cooling effect of the back plates  6 A and  6 B is by natural convection and conduction, which occur continuously during and at the end of the delivery of the graphic design after the heated mold die member retracted away of the substrate. The heating of the back plate  6 A and  6 B occurs as a residual of the heat transfer from the hot thermosetting polymers being injected onto the substrate. The contact pressure of the die set  75 , as it contacts a pressure sensor as the die set  75  moves down during to start the injection cycle of thermosetting polymers onto substrates, is predetermined accordingly to set the appropriate air gap sufficient to evacuate the gas forming during the heating of the thermosetting polymer. The selection of contact pressure of the die set  75  will preferably include the steps of selecting a predetermined range of appropriate contact pressures of the die set  75 . For typical types and grades of thermosetting polymers, the contact pressure of the die set  75  during injection may range from about 50 to 600 psig. The preferred range of contact pressure between the die set  75  and the pressure sensor during injection varies as a function of the types and grades of the thermosetting polymers.  
      The selection of the contact pressure is predetermined and entered in the programmable functions of the PLC  13 . As part of the system control, the PLC  13  will receive a database for predetermined quantity of silicone resin, or other thermosetting polymer resin and also known as a silicone shot, which will be selected for injection into each of the mold cavities  51  of the mold die member  11 . The selection of the quantity of silicone resin for injection into each of the mold cavities  51  of the mold die member  11  will preferably include a selection of a separate quantity for each mold cavity  51  of the mold die member  11 . Using this application, a plurality of supplies of silicone resin may be controllably and diversely, in quantity, injected into the mold cavities  51  of the mold die member  11  from a plurality of supplies of silicone resin  21 . Typically, the quantity of silicone resin injected into each mold cavity  51  of the mold die member  11  may range from about 1 to 150 grams. In a preferred embodiment with complicated three-dimensional graphic designs onto clothing, the quantity of silicone resin injected into each mold ranges from about 1 to 75 grams. The desired quantity of thermosetting polymer resin selected for injection into each mold cavity  51  of the mold die member  11  will vary as a function of the particular three-dimensional design selected for placement onto a substrate.  
      Continuing the start-up procedure, the operator then positions and aligns the substrate upon the back plate  6 A or  6 B and then initiates the molding cycle.  
      Under control of the PLC  13 , the molding cycle consists of initializing air cylinders  4 A and  4 B, lowering the die set  75 , initializing the air cylinders  24 A or  24 B, moving the back plate  6 A or  6 B into the predetermined position, starting the injection of silicone resin supplies  21 , stopping injection of silicone resin supplies  21 , raising the die set  75 , moving the die set  75  horizontally to the location of the next back plate  6 B or  6 A, moving the back plate  6 A or  6 B horizontally away from strike zone of the die set  75 , removing the completed substrate, and automatically restarting the cycle after another substrate is deposited on the back plate  6 A or  6 B. Upon initiating the molding cycle, the silicone resin, or other thermosetting polymer resin, supply system  80  will load one or more silicone resin injection pumps  26  with the predetermined quantities of silicone resin, or other thermosetting polymer resin, to be injected. Alternatively, a mixture of different thermosetting polymer resin supplies may be provided that will permit three-dimensional bodies of a plurality of thermosetting polymer resins of multiple colors to be molded onto a substrate.  
      During the step of lowering the die set  75 , the hydraulic actuator  1  controllably lowers the die set  75  into position with the garment  57 , which is located and aligned upon the back plate  6 A or  6 B. In a preferred embodiment, the operation of the hydraulic actuator  1  is controlled by the control system  90 . In a particularly preferred embodiment, the position of the hydraulic actuator  1  as well as the contact pressure of the die set  75  with pressure sensor are monitored and controlled by the control system  90 . Upon engagement of the die set  75  with the garment  57 , the operational step of injecting silicone resin supplies  21  begins.  
      The operating pressure and flow rate of the silicone resin injected into the mold cavities  51  may be limited, for example, to the range of about 200 to 800 psig and 0.33 to 0.50 in 3 /sec in order to prevent damage to the article of clothing. In a particularly preferred embodiment, the operating pressure and flow rate of the silicone resin injected into the mold cavities  51  are limited to the range of about 300 to 600 psig and 0.01 to 0.33 in 3 /sec in order to prevent damage to the article of clothing. Alternatively, the preferred range of operating pressures and flow rates will vary as a function of the type and thickness of the substrate.  
      The curing of the silicone resin supplies  21  is integrated in the heat transfer process and the silicone continues to cure, after the injection cycle is complete, in a conventional way. During the injection cycle, the die set  75  is maintained in engagement with the article of clothing  57 , or other substrate, within an air gap  50  for a predetermined time period to allow the graphic design to be completely delivered for the fully predetermined amount of silicone resin, or some other thermosetting polymer resin, in a place as the article of clothing  57 , or other substrate is positioned and aligned. For typical types and grades of silicone resin, the curing time and temperature may range, for example, from approximately 5 to 50 seconds and 200° to 500° F. In a preferred embodiment, the heat transfer occurs within time and temperatures range from about 10 to 30 seconds and 300° to 900° F. The heat transfer times and temperatures will vary as a function of the particular type of thermosetting polymer selected as well as the number and volume of the mold cavities  51  of the mold die member  11 . Once the silicone resin, or other thermosetting polymer resin is fully deposited according to a predetermined graphic design, the die set  75  is raised out of engagement with the article of clothing  57 , or other substrate.  
      During the step of raising the die set  75 , the hydraulic actuator  1  controllably raises the die set  75  out of engagement with the article of clothing  57 , or other substrate and the air cylinders  4 A and  4 B controllably transport the die set  75  horizontally to engage the next article of clothing  57  or substrate. The control system  90  then once again initiates the molding cycle.  
      In the preferred embodiment, the flow of silicone resin into the die set  75  can be timely stopped by using flow control valves, which can be closed within a time period ranging from about 125 to 500 msec and injection pumps  26 A,  26 B,  26 C,  26 D and  26 E.  
      In a particularly preferred embodiment, the operational steps described above are all controlled and monitored by the control system  90 . Alternatively, the operational steps described above are implemented using any number of thermosetting polymers including, for example, silicone, nitrile rubber or urethane. Furthermore, the operational steps described above are implemented using a combination of different thermosetting polymers having similar curing characteristics, including such combinations as, for example, silicone, nitrile rubber or urethane.  
      Drawing  FIG. 32  illustrates a preferred embodiment of an article of clothing  57  including one or more three-dimensional bodies of silicone, or other thermosetting polymer  59 A,  59 B,  59 C,  59 C,  59 D and  59 E.

      The three-dimensional bodies of silicone  59 , or some other thermosetting polymer, are preferably molded onto a T-shirt  57 , or some other substrate, by adhesion as the silicon resin or some other thermosetting polymers are injected under pressure onto the fibers of the T-shirt  57 , or some other garment or substrate to create a bond at the surfaces of contact of the T-shirt  57  and the silicone resin supplies  21 . In this manner, the three-dimensional bodies of silicone  59 , or some other thermosetting polymer, are permanently affixed to the T-shirt  57 , or some other garment or substrate as the polymers cool and solidify the bonding surfaces. The bonding surfaces are formed on the outside surface of the fabric of the T-shirt  57  or some other garment or substrate and the corresponding contact surface of the graphic design.  
      In a particularly preferred embodiment, one or more of the three-dimensional bodies of silicone, or some other thermosetting polymer,  59 , may further include at least one encapsulated element such as a beeper, liquid crystal display, holograph, or other device.
