Open type press generally refers to a crank press, which is a forging machinery that uses mechanical transmission. Through the transmission system, the motion and energy of the electric motor are transmitted to the working mechanism, thereby enabling the billet to obtain a determined shape.

The new technology of the open press is driven by Kehui's switched reluctance servo motor, eliminating rigid clutches and achieving emergency braking at any point, eliminating the hidden danger of hand pressure and ensuring personal safety.
