SURFACE PROCESSING METHOD FOR A MOLDED METAL HOUSING

A surface processing method for forming a predetermined pattern on a molded metal housing includes forming an isolation layer related to the predetermined pattern onto the surface of the molded metal housing and etching the surface of the molded metal sheet. The isolation layer is used for defining...

Zusammenfassung:	A surface processing method for forming a predetermined pattern on a molded metal housing includes forming an isolation layer related to the predetermined pattern onto the surface of the molded metal housing and etching the surface of the molded metal sheet. The isolation layer is used for defining whether the surface of the molded metal sheet covered by the isolation layer is etched or not.
