METHOD OF MONITORING INJECTION PRESSURE.

摘要

A method of monitoring an injection pressure by monitoring and displaying on a screen the relation among the position of the screw, injection pressure, and the quantity of material filled in the cavity in the injection molding machine, in which pressure relative to the position of the screw (1) is graphically shown (A1) on the screen (119) and a drawing (A3) of the cavity is shown on the screen. By inputting a position of the screw, pressure relative to said position is monitored and, at the same time, a state in the cavity filled with resin corresponding to said screw position is shown as an image.
