1. Electroplating: Commonly used metal parts are electroplated with zinc, nickel, chromium, copper, etc., to prevent corrosion, improve wear resistance, enhance aesthetics, etc.
2. Anodizing: commonly used for surface treatment of aluminum alloys and is an essential process
3. Blackening treatment: It can maintain the dimensional accuracy of the parts and has a corrosion-resistant and aesthetically pleasing effect
4. Spray coating: mainly used for anti-corrosion of external components, such as frames, etc
5. Polishing: Polishing refers to the processing method of using mechanical, chemical, or electrochemical effects to reduce the surface roughness of a workpiece, in order to obtain a bright and smooth surface
6. Rolling pattern: Rolling pattern is a mechanical process of rolling patterns on the pinching or other working surfaces of metal products, mainly for anti slip purposes.
7. Drawing: Drawing treatment can give the metal surface a non mirror like metallic luster, while also eliminating subtle defects on the metal surface.
8. Dacromet treatment: Similar to electroplating, domestically named as zinc chromium coating
