Abstract

PURPOSE:To suppress the radical change so as to obtain a molded item with uniform quality, by dividing an injection stroke into several steps, and while detecting the proceeding speed of an injection screw and the hydraulic pressure, controlling of said proceeding speed and the hydraulic pressure in accordance with a predetermined program is performed. CONSTITUTION:In the filling step of an injection molder, the proceeding speed of the screw or injection plunger is controlled in accordance with a predetermined program, the change from the filling step to the compression step or from the compression step to the filling step is controlled based on the positions of the plunger, etc., in the compression step the pressure set value of the injection cylinder hydraulic pressure is predetermined to be approximately equal to the pressure value at the end of this step, in the compression step the floating control is performed based on the balance of the speed of the plunger or the injection screw, the injection cylinder hydraulic pressure set value and the load, and the pressure maintaining step is controlled based on a predetermined period.
