ABSTRACT:
An injection pressure waveform for use as a target value for injection pressure feedback control is set based on the actual injection pressure waveform detected when a conforming molded article is obtained. Alternatively, the target injection pressure waveform may be set by modifying a previously retained injection pressure waveform or an actual injection pressure waveform. The previously retained injection pressure waveform or actual injection pressure waveform is displayed on a screen of a display device (T1). Two points on the displayed injection pressure waveform are assigned, and the pressure waveform is modified into a line connecting these two points (T3,T6,T8). Further, two points on the injection pressure waveform and one point between these two points are assigned, and the pressure waveform is modified into a circular arc connecting these three points (T4,T7,T8). The injection pressure waveform modified in this manner is set as the target value for the injection pressure feedback control (T8,T9).
