Cold Pressing
Taking advantage of the characteristics of plastic deformation of metal, the microscopic convex peaks on the surface of the workpiece are flattened by applying pressure, thereby reducing the surface roughness. High pressure is applied in the mold cavity to make a compact molded blank. Including surface rolling, surface extrusion processing, etc. Suitable for polycarbonate, polypropylene and other materials. By cold pressing processing, the tensile strength and elastic modulus of the material can be improved
