4-column hydraulic press is a kind of mechanical equipment that uses the static pressure of hydraulic oil delivered by oil pump to process metal, plastic, rubber, wood, powder and other products. The four-column hydraulic press consists of two parts: the main engine and the control mechanism.

Four Columns Hydraulic Press Machine

The main part of the hydraulic press includes hydraulic cylinders, beams, columns and liquid filling devices. The power mechanism consists of a fuel tank, a high-pressure pump, a control system, an electric motor, a pressure valve, and a directional valve.

The hydroforming process of the four-column hydraulic press has a wide range of applications in the automotive, aviation, aerospace and pipeline industries. The hydroforming process of the four-column hydraulic press is mainly suitable for: hollow structural parts with circular, rectangular or special-shaped sections that change along the axis of the component, such as automobile exhaust system special-shaped pipe fittings; non-circular section hollow frames, such as engine brackets, instrument panel brackets, body frame hollow shafts and complex pipe fittings.
