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.
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.

Pacific Press Technologies
Pacific Press Technologies is a world leader in the design, manufacture and service of hydraulic presses, press brakes and automation solutions. Founded in 1945, Pacific made a name for itself by producing the world’s first hydraulic press brake. The concept quickly caught on as the industry recognized hydraulic brakes as a safer alternative to mechanical press brakes.
Over the years, Pacific has installed more than 15,000 machines in North America, maintaining its leadership in press brakes and press brake equipment. Pacific is known for its extremely rugged and reliable designs, and is engineered and manufactured stateside. From 100-ton presses to 3,000-ton press brakes, Pacific can custom design and build the right machine for your application.
