ABSTRACT:
A reference pressure waveform for injection molding operation is set in advance; pressures corresponding to the pressure waveform are detected with predetermined detection times during the injection molding operation; pressure deviations between pressure stored in the pressure waveform, corresponding to the detection times, and the detected pressures are obtained; and the pressure deviation for each detection time is graphically displayed on a display screen along with the reference pressure waveform.
