Hydraulic presses adopt plug in tegrationsystem,it has its own indelpedent dynamic mechansim.It assumes adjust the ring singlecycle,(with feeding device)contnue working operation modes. Through the operating panel selection, the constant pressure shaping technology can be realized. These presses have good rigidity,high precision. It is sultable for press-fitting,calibrating,stretch,bending,revers,etc. It is also suitable for powder metallurgic products, autocar-unit domestic electric appleance, kitchen-wares squelch shaping technology.
