The press body will be heat treatment and sand blasting. Press structure is optimized by computer and all the key power points are strengthened.


JS31 H frame single point press uses eccentric gear transmission system.This type press is more suitable for thin drawing, thick sheet blanking and hot forging process. Eccentric gear transmission system ensures bigger stroke length and bigger nominal tonnage stroke length.

The grinded helical gear or herringbone gear makes the moving more stable with lower noise.


Press with pneumatic clutch can work as continuous, inches or single stroke,more choices for operators. Brake system can stop the press at any point especially for emergency stop.
