Abstract

An approach to controlling the cavity temperature of the molded part during the cooling cycle of an injection molding machine is developed. The controlled variable is chosen as the average cavity temperature which is used during the cooling cycle. The coolant flow rate in the mold is used as the manipulated variable. An adaptive predictive controller is used to maintain a given average cavity temperature setpoint with existing disturbances. The control strategy was simulated and tested in an industrial scale injection molding machine.
