Abstract

A hold pressure control start pressure for resin injection molding is determined by finding a pressure (Ps) at which a pressure curve (H) representing the pressure on a resin melt inside the mold cavity forms a valley (J) occurring first after a peak of the pressure curve, and setting the thus found pressure (Ps) as a hold pressure control start pressure that is used for performing pressure control during a subsequent resin molding operation. Since the hold pressure control start pressure is determined on the basis of the pressure curve, it is essentially possible to obtain a setting pressure value for such hold pressure control start pressure through a single run of test injection molding process.
