Standard Execution
Heavy, one-piece welded steel frame is designed to resist deflection, providing more accurate stampings and longer die life.
Fast-response hydraulic overload relieves the pressure of a tonnage overload in milliseconds, stopping the press immediately and
protecting press and dies from damage.
Wet clutch and brake provide long life, very low maintenance, and high performance even at high single-stroking rate
