Automatic Post-Press Equipment Flat Bed Die Cutting Machine With Stripping

Advantages

1) Transmission of main unit adopt imported A/C frequency converter control, startup and stop of the machine are controlled by means of imported air clutch.
2) Running of the whole machine is controlled by PLC. Interface touch-screen for monitoring machine running condition, trouble indications and their corresponding shooting ways. This is more operator-friendly.
