Abstract

Cavity pressure control in injection molding is important to maintain product quality in injection molding process. The coolant flow rate and temperature are parameters affecting the cavity pressure profile during cooling stage. A coolant flow rate control system has been designed and implemented to provide consistent heat removal from the mold cycle-to-cycle. Good and effective cavity pressure control was obtained by controlling the coolant flow rate using a predictive controller.
