Abstract

Many investigations have emphasized the importance of cavity pressure in determining final part quality in an injection molding machine. During the injection cycle, the main factor affecting cavity pressure is the screw hydraulic pressure valve Y3. Cavity pressure has some nonlinear characteristics, thus an advanced control strategy is developed. Experiments quantified the relationship between the nozzle pressure and the Y3 valve in order to design a predictive controller. The controller was implemented with good closed loop results.
