YL102 Die Casting Motor Parts-FRONT HOUSING

The surface treatment of this motor parts is hard anodizing.It is very important and difficult in the CNC process,because we need to protect the anodizing area accurately.
Anodizing is a simple electrochemical process that forms a protective coating of aluminum oxide on the surface of the aluminum die casting parts. The rusting of unprotected iron in the presence of air and water is then inevitable because it is driven by an electrochemical process. The lifetime of the finish is proportional to the thickness of the anodic coating applied.
The process has been in vogue since 1960. Aluminum oxide, as we all know, is a hard, durable and weather resistant substance that protects the base metal. The coating may be either colored by dyeing or it may exhibit bronze tones through diffraction phenomena produced by the coating. The coating is integral to the metal and will not peel or flake. In general anodizing is less expensive than painting with the exception of coil painted products.
Anodizing is particularly preferred for aluminium die casting in high traffic areas where the coating is subject to physical abuse and abrasive cleaners.
