The machine is suitable for plastic material pressing process, such as stamping, bending, flanging, sheet metal stretching process can also be used to correct, press-fit, wheel forming, cold extrusion forming metal parts, plastic products and powder products molding process . This machine is a centralized button control can be achieved manually adjust and semi-automatic cycle of the two practices. Working pressure machine, express down and slow down the downward stroke range can be adjusted based on operational need. It can achieve with the top division, and without ejecting the way the two processes, each process in another way and given the constant pressure molding process forming operation two processes available. After pressing the master cylinder has a packing, delay and return functions, there are top of the delay, returned to action and so on and ejection. When Paul rolled and the top of the time delay set by the time relay can be adjusted. This machine has independent power system to move freely from inside the fuselage, easy to adjust and maintenance. Department of Hydraulics plate valve integrated, compact, and reliable operation.
