Several common methods of aluminum surface treatment in precision hardware processing


1.Polishing: It can overcome defects, remove burrs and make the surface bright.

2.Sand blasting: The purpose of precision metal processing 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., which show different feelings, similar to the rough and dry texture of ground glass, and fine sand mold can also show high-grade products.

3.Electroplating: relatively common, and there is also a treatment process of electroplating after polishing.

4.Veining: it is a treatment method of re-processing after mold forming, and the pattern is processed by lathe. The adult body shows very regular texture features.

5.Wipe pattern: it is called wire drawing, and its performance is similar to that of car pattern, which is smooth and continuous on the surface. The difference is that car pattern is circular pattern, and wipe pattern is linear pattern.

6. Oxidation (coloring): aluminum surface treatment oxidation can be used in two ways to enhance physical properties and achieve the purpose of coloring. We often see some metal nameplates, on which the product or company logo has inclined or straight filiform stripes. This is the edge of the embroidery process, similar to the polishing and electroplating effect, but the processing method is different, and the effect is different. The processing method is mechanical processing, showing a very bright and bright effect.
