METHOD FOR MONITORING PRESSURE IN FILLING/DWELLING STEPS AT MOTOR-DRIVEN INJECTION MOLDER

摘要

PROBLEM TO BE SOLVED: To provide a pressure monitoring method by which the maximum value of a resin pressure during molding can be assuredly monitored without being influenced by the high speed and highly sensitive response of a motor. SOLUTION: The operation to detect a resin pressure during molding at a motor-driven injection molder is performed concerning the maximum value of the pressure throughout the process including a filling step and a dwelling step.
