A molding system being configured to manufacture a molded article in a mold-cavity system by using a molding material, the molding system comprising: a pressure-control system being coupled with the mold-cavity system; and a controller operatively coupling to the pressure-control system, the controller having a controller-usable memory tangibly embodying a set of controller-executable instructions being configured to direct the controller, the set of controller-executable instructions including: mold-unpack instructions, including instructing the controller to control the pressure-control system to reduce, after solidification, at least in part, of the molding material being located in a nub region of the mold-cavity system, internal pressure of the molding material received in the mold- cavity system while the mold-cavity system remains isolated from a stream of flowable-molding material, beyond any reduction of the internal pressure in the molding material resulting from cooling of the molding material, so that the reduction in the internal pressure of the molding material is enough to permit safe opening of the mold-cavity system while permitting safe extraction of the molded article from the mold-cavity system, wherein the controller is instructed to deactuate the pressure-control system so as to remove pressure to a core portion of the mold-cavity system, so that the volume of a mold cavity of the mold cavity system becomes relatively larger and pressure reduction is realized in the mold cavity. a pressure-control system being coupled with the mold-cavity system; and a controller operatively coupling to the pressure-control system, the controller having a controller-usable memory tangibly embodying a set of controller-executable instructions being configured to direct the controller, the set of controller-executable instructions including: mold-unpack instructions, including instructing the controller to control the pressure-control system to reduce, after solidification, at least in part, of the molding material being located in a nub region of the mold-cavity system, internal pressure of the molding material received in the mold- cavity system while the mold-cavity system remains isolated from a stream of flowable-molding material, beyond any reduction of the internal pressure in the molding material resulting from cooling of the molding material, so that the reduction in the internal pressure of the molding material is enough to permit safe opening of the mold-cavity system while permitting safe extraction of the molded article from the mold-cavity system, wherein the controller is instructed to deactuate the pressure-control system so as to remove pressure to a core portion of the mold-cavity system, so that the volume of a mold cavity of the mold cavity system becomes relatively larger and pressure reduction is realized in the mold cavity. mold-unpack instructions, including instructing the controller to control the pressure-control system to reduce, after solidification, at least in part, of the molding material being located in a nub region of the mold-cavity system, internal pressure of the molding material received in the mold- cavity system while the mold-cavity system remains isolated from a stream of flowable-molding material, beyond any reduction of the internal pressure in the molding material resulting from cooling of the molding material, so that the reduction in the internal pressure of the molding material is enough to permit safe opening of the mold-cavity system while permitting safe extraction of the molded article from the mold-cavity system, wherein the controller is instructed to deactuate the pressure-control system so as to remove pressure to a core portion of the mold-cavity system, so that the volume of a mold cavity of the mold cavity system becomes relatively larger and pressure reduction is realized in the mold cavity.
