Features of power press

The frame of the power press can incline about 25 degrees to facilitate blanking.
The slide is a cast box-shaped structure with good rigidity.
Rigid overload protector is installed inside the slide. With simple structure, when the slide overloads, the protector is collapsed and destroyed, so as to protect the metal stamping machine and mold from being damaged.
The slide die height implements manual adjustment, with scale display.
Four-sided triangular lengthened guide with easy adjustment
Rigid type single revolution clutch
