The JH21 C-frame single crank press is suitable to process the lightweight and thin materials through blanking, piercing, bending, forming, interlink with ROT line or transfer unit. Suitable for single and progressive die application, and it owns the capacity ranging from 25 ton to 400 ton.
The press use high torque and low noise wet clutch and brake.
The steel welded body ensures rigid frame with less deflection. High accuracy transmission gears and high rigidity crank ensure press long life and accuracy.
Forced lubrication system with default monitor ensures the operation reliability. User-friendly design and all-function electric control system enable the accessories to attach easily.
