Abstract: <P>PROBLEM TO BE SOLVED: To provide an injection molding system having a self-regulating valve for balancing melt flow.  <P>SOLUTION: The self-regulating valve includes a control rod configurated to balance through a hot runner system. The self-regulating valve reacts to an injection or melt pressure within the hot runner system and a pre-set force provided by an external force device. The self-regulating valve is an open-loop system as it requires neither a measurement of pressure by a sensor nor feedback from a processor in order to regulate the melt flow. The self-regulating valve mechanically reacts to changes in melt pressure on control surfaces thereof by "bobbing" upwards/downwards to decrease/increase the melt flow accordingly. The self-regulating valve compensates for conditions that affect melt pressure, such as an increase/decrease in melt viscosity, changes in melt temperature, and/or mold cavity size without the use of a processing device.  <P>COPYRIGHT: (C)2008,JPO&INPIT
