JW31 straight side press machine uses a strong H frame body. The press body is steel welded

with high quality steel plates by carbon dioxide arc welding. After welding, all the weld seams must pass the examination of ultrasonic inspection. The top transmission gearbox is tested by oil bath to avoid any oil leak.

Then, the press body will be heat treatment and sand blasting. All these treatments will help to release the welding stress for high rigidity. Press structure is optimized by computer and all the key power points are strengthened.


Wet type pneumatic clutch with imported clutch disc, NOK seals, lower noise and maintenance cost, longer service life.

Press with pneumatic wet clutch can work as continuous, inches or single stroke, more choices for operators.

Siemens Motor, Schneider Electric Components

The press is equipped with Siemens main motor and Schneider electric components.

Hydraulic Overload Protected Pump

The press will stop immediately once it is overload than 110% to protect both the press and the die. It is easy to reset the overload as there is a reset switch on the control panel. The system can be reset within 3 minutes.


Panasonic or Omron or Schneider PLC
