Common Surface Treatment Processes for Aluminum Alloy Die Casting

　　With the advancement of technology, the outer layer treatment techniques of aluminum alloys have become increasingly diverse, and each technique has a different surface effect, so the application methods are also different. Do you know the common surface treatment processes for aluminum alloy die-casting?

　　1. Metal electroplating is quite common, and there is also a process of polishing and electroplating treatment.

　　2. Oxidation, aluminum surface treatment. The purpose of oxidation is twofold: to enhance physical properties and achieve coloring.

　　3. Scratching, also known as drawing, is similar to car patterns in appearance, both of which form smooth and continuous patterns on the surface. The difference is that car patterns appear as circular patterns, while scratch patterns appear as straight line patterns.

　　4. The purpose of sandblasting and aluminum surface treatment is to cover up some defects generated by aluminum alloy during mechanical processing and meet some special requirements of customers for product appearance.

　　5. Polishing has the function of overcoming product defects, removing burrs, and making the surface shiny.
