SLG Series｜Straight Side Crank Link-Motion Press

This series is the prime choice for large parts forming, which makes it applicable for automotive parts forming. The crank shaft and connecting rods are adopted to drive the gear component. The soft contact during forming extensively reduces vibration, noise and heat, as well as extending die lifetime. The design of low energy consumption can effectively save more than 20% of energy.

Designed with tie-rod structure on the frame and adopting gear driving component with four connecting rods, the rigidity of main body increases extensively.The soft contact during press forming extensively reduces vibration, noise and heat, as well as extending die lifetime.
The combination of pneumatic die cushion for big tonnage with tightening and adjusting component can address the needs for different stroke and action.
With the use of high torque wet clutch/ brake, the lifetime of clutch increases and environmental protection is ensured.
The highly respondent Hydraulic Overload Protector (HOLP) can effectively fix die stuck and prevent overloading.
The human-machine interface can precisely control the stroke and pressure applied onto the die cushion. With PLC monitoring, the status of machine usage can be controlled at all times.
