Abstract: Control systems of outside processing mechanism for plastic parts was designed by use of Mitsubishi FX3U type PLC on the basis of process principle of outside processing for plastic parts. This control system included an automatic mode and a manual mode. The connection with the PLC control system was established. The variables were defined, and the animation was connected through the supervisory control and data acquisition. Moreover, the automatic control of plastic outside molding and processing was achieved, and the motor speed and flow rate of electrohydraulic proportional valve were also accurately controlled.

Key words: plastic outside processing, process principle, control system, animation connect, electro-hydraulic proportional
