Common surface treatments for aluminum die castings include electrophoresis, plastic spraying, painting, electroplating, and oxidation. These surface treatments can be divided into two categories according to the surface type: the material addition method of adding a metal coating or resin paint lay
Die casting is a highly efficient liquid metal forming method with less and no cutting.
