[0002] A metal shield is a highly efficient electromagnetic shielding material that uses the conductivity of metal to prevent electromagnetic waves from penetrating, thereby forming a closed metal environment to protect and isolate electronic equipment. The main materials of metal shields are aluminum alloy, magnesium alloy, stainless steel, etc., and are made by mold stamping. Before stamping, stamping oil needs to be applied to the surface of the material. The stamping oil forms a lubricating film between the mold and the material, reducing the friction between the mold and the material, reducing stress, and also playing a certain cooling role.
