What are the surface treatments of aluminum precision parts after processing

With the improvement of people's living standards, consumers' sense of experience is getting higher and higher. The appearance of a product represents its quality, experience and expectations. Many products will give priority to the use of aluminum alloy in the selection of materials, because it can have A variety of surface treatment methods allow the product to show its due beauty. The following is a detailed discussion of the surface treatment of precision aluminum CNC parts?

1. Oxidation

Oxidation is divided into single-color oxidation and multi-color oxidation. Multi-color oxidation means that a product has several dazzling color effects at the same time. VMT can make up to 4 or more colors appear on the same product.

2. Sandblasting

Sandblasting is a relatively complicated surface treatment process. The specifications and materials of the sand are different, and the effect produced is also different. Just like the Apple mobile phone uses B70 ceramic sand for special sandblasting, mainly because its shape is round. Ball, high hardness, long life and other effects, so the surface effect it produces is uniform and beautiful.

3. Electroplating

It can be made in various colors. Aluminum alloy electroplating has high requirements on the surface treatment process, otherwise trachoma, blisters, black spots, etc. will appear if the treatment is not done properly. VMT has done a lot of experiments on this process and has a complete set of solutions. We have developed a zinc-nickel alloy electroplated aluminum alloy CNC part for Plantronies of the United States, and it has passed the 100H salt spray test.

4. Corrosion carving pattern

This process can make a lot of patterns on the surface of the part, so that the product can get a better appearance. Although there are many processes for oxidation after corrosion and engraving of aluminum alloy metal, there are not many factories that really achieve a yield rate of more than 90%.
