Surface Treatment
What are the surface treatments for aluminum?
1. Metal electroplating method: relatively common, and there is a process of electroplating after polishing.
2. Oxidation (coloring): The purpose of aluminum surface treatment and oxidation is divided into two aspects, which can enhance the physical properties and achieve the purpose of coloring.
3. Scratch pattern: it is called brushed pattern, which is similar to the chevron pattern. It is a smooth continuous pattern formed on the surface. The difference is that the chevron pattern is a circular pattern, and the scratch pattern is a linear pattern.
4. Sand blasting: the purpose of aluminum surface treatment is to overcome and cover up some defects of aluminum alloy during machining and meet some special requirements of customers for product appearance. There are glass sand, tungsten sand, etc., showing different feelings, similar to the rough texture of ground glass. Fine sand mold can also show high-end products.
5. Polishing: It can overcome defects, deburr and brighten the surface.
6. Lathing: aluminum surface treatment is a processing method for re processing after mold forming. Lathe is used to process the grain, which is generally characterized by extremely regular texture.
