This series of hydraulic presses are suitable for the pressing process of metal materials, such as stamping, bending, forming, extrusion, sheet drawing and pressing of powder products, and can also be used for hot pressing of plastic products. With independent hydraulic pump station and electrical control system. The hydraulic control adopts a cartridge valve integrated system. The oil pressure is displayed by a digital display electric contact pressure gauge, and the upper limit of the oil pressure can be set within the allowable range as required. The electrical system is centrally controlled by buttons, and has two operating modes: jog and semi-automatic. The working pressure and stroke can be adjusted within the specified range as required, and two molding methods of constant pressure and fixed stroke can be completed.
