Extrusion forming is a plastic processing method in which substantial pressure is applied to metal blanks placed in a mold cavity (or extrusion barrel), compelling the metal blanks to undergo directional plastic deformation. This results in the extrusion of metal through the die hole of the extrusion mold, obtaining the desired cross-sectional shape, dimensions, and certain mechanical properties of parts or semi-finished products. Compared to stamping and cold heading processes, extrusion forming is suitable for workpieces made of easily deformable materials such as copper, aluminum, and low-carbon steel, especially when the shapes are simple but significant deformation is required. Applications of extrusion processes in automotive components include sunroof guides, bumper impact beams, battery trays, radiator brackets, steering components, and more. According to the direction of metal plastic flow, extrusion processes can be categorized as forward extrusion, backward extrusion, composite extrusion, and radial extrusion.
The 800-ton four-column hydraulic press is a commonly used forging machine tool, characterized by a compact structure and versatile hydraulic extrusion press. It adopts a three-beam four-column structure design, offering wide applicability and high production efficiency. The 800-ton four-column hydraulic press processes metal blanks into the required automotive components by applying significant pressure, inducing plastic deformation and fracture.
