What are the surface treatments of aluminum precision parts after CNC machining

Many products will consider giving priority on the use of aluminum alloy in the selection of materials since it can have a variety of surface treatments, so that the product shows its due beauty. 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 and experience and expectations.

1. Oxidation

Monochrome oxidation and multi-color oxidation are two forms of oxidation; multi-color oxidation is the result of which numerous brilliant color effects are simultaneously. VMT can show on the same product up to four or more colors.

2. Sandblasting

Just like the Apple mobile phone uses B70 ceramic sand as a special sandblasting, mostly because its shape is a round ball, high hardness, long life and other effects, so producing a uniform and beautiful surface effect. Sandblasting is a more complex surface treatment process with different specifications and materials.

3. Plating

Aluminum alloy electroplating has great criteria for the process of surface treatment; otherwise, if the treatment is not done correctly, trachoma, blistering, black spots, and other circumstances would follow. It can be done in several colors. Hansheng has conducted a lot of research on this technique; we developed a zinc-nickel alloy electroplated aluminum alloy CNC component for the United States customer, and passed the 100H salt spray test; there is a full solution.

4. Corrosion of engraving patterns

This method can produce many surface patterns on the part that help the product to look better. Although re-oxidation following corrosion and engraving of aluminum alloy metal is a process with numerous steps, few manufacturers truly reach a yield rate of greater than 90%. We have also gained a lot of knowledge and created several similar process components. First we will discuss the corrosion process here; next time we will go into more particular depth.

You are welcome to investigate with us based on the preceding knowledge; I'm not sure whether you have a deeper awareness of the surface treatment of aluminium alloy parts following CNC machining.
