Injection Molding Machinery Injection Molding Machine Hydraulic Oil Circuit System Monitoring PT03 pressure transmitter, acquire pressure value of the hydraulic oil circuit system of the injection machines in real time: injector control, ejector control, and mold closure, so as to provide reliable closed-loop control feedback signals for the stable operation of the hydraulic system. Injection Force Monitoring The injection molding needs to reach the specified force value, FC50 force sensors could send the signal when the molten liquid reach the limited force value to realize high accuracy injection control.
