A. The oil pressure is the source of power, and it is characterized by large pressure, stable liner velocity, noise proof and low fault rate. B. Designed for wide-column, strong mechanical rigidity, stable in processing C. Three layers mode for SUP type, strong mechanical rigidity, stable in processing. Within 0.02m/m parallel precision, compared with large punch machine, it is cheaper by several times. D. The stroke of movement is large. It can possess high impulse force in the whole stroke, or low pressure under no load, or high-pressure movement under load. E. Complete safety setting, and it is activated by double buttons+ emergency button+ adjusting stopping time of decline+ automation and manual (adjust mould) electrical circuit design, and the upper and lower limit switches are assembled to adjust the stroke.
