Abstract

An injection molding machine includes a cylinder; a screw; a rotary driving unit; a reciprocation driving unit; a pressure detector that detects a pressure of a molding material in front of the screw; a control unit that performs a first type of plasticizing process where the screw is moved backward to a predetermined position and rotated at the predetermined position to transfer the molding material forward to reserve the molding material in front of the screw, performs a first type of filling process where the screw is moved forward to inject the molding material reserved in front of the screw in the first type of plasticizing process from the cylinder to be filled in a mold unit, monitors the pressure in the first type of filling process by the pressure detector, and corrects the setting of the first type of filling process based on a monitored result.
