This series of four column hydraulic presses have a wide range of versatility. Host three beam and four-column structure. The ram is guided by four-column. Ejection cylinder puts in a hole in the middle table. Arranged operation table in the right of front fuselage. Component parts are distributing in the control panel box. Provide whole series of typical single-cylinder technology action, anti-stretching movement, and release moves, floating press border action. Applicable to a variety of plastics’ press processing and forming. As a result of the addition of a floating piston cylinder top edge of the process pressure moves the cylinder can be done using the hydraulic top cushion, the use of technology to achieve tensile stretch forming sheet metal, such as bending, Flanging, extrusion, stamping and other technological requirements.
