Four-column hydraulic press

Four-column hydraulic press is a machine made by using Pascal's law and utilizing liquid pressure transmission. Four-column hydraulic press is a kind of mechanical equipment that uses the static pressure of hydraulic oil to transport hydraulic oil to process metal, plastic, rubber, wood, powder and other products. It is commonly used in pressing processes and forming processes, such as: forging, stamping, cold extrusion, straightening, bending, flanging, sheet drawing, powder metallurgy, press fitting, and so on.

★ This series of hydraulic presses are universal pressing equipment, suitable for the pressing process of plastic materials. Such as powder product molding, plastic product molding, cold (hot) extrusion metal molding, sheet metal extension and stamping, bending, flanging, correction and other processes.

★ The machine has an independent electrical system of the power mechanism, and adopts centralized control of buttons, which can realize three working modes of adjustment, manual and semi-automatic;

★ The machine's working pressure, pressing speed and slider stroke can be adjusted according to process requirements, and can complete the ejection process, without ejection process, and stretching process. Each process is fixed pressure, Two process actions of fixed stroke are available for selection. The fixed pressure forming process has pressure retention, time delay, and automatic return stroke after pressing.

★ In addition to the above functions, this series of hydraulic presses also have ejection, delay and automatic return.
