Powder coating of aluminum profiles is actually a kind of powder spraying. It is an aluminum alloy profile or work piece on the surface of powder coating with powder spraying equipment (electrostatic spraying machine), and then under the action of static electricity, the powder will be uniformly adsorbed on the aluminum surface to form powder coating, and then after high temperature baking and leveling, it will become a kind of Coatings with different effects. This process is called aluminum profile powder coating.

The purpose of powder spraying of aluminum profiles is to improve the adsorption and adhesion of the surface of industrial aluminum profiles, increase the corrosion resistance and oxidation resistance of the surface of aluminum profiles, and improve the appearance quality and mechanical properties of aluminum profiles. At the same time, it can also remove oil, dust and other sundries on the surface of aluminum profiles.

Process flow of powder coating for aluminum profile processing: pre-treatment (oil removal→water washing→chemical conversion→water washing→drying)→electrostatic powder coating→leveling and curing

Advantages of powder coating of aluminum profiles:

1. Automatic production, produced with mechanical equipment, no need to manually spray aluminum profiles one by one;

2. Powder coating of aluminum profiles can be carried out at room temperature without preheating aluminum profiles;

3. Cost savings, powder coatings can be recycled, which greatly saves Enterprise cost;

4. The thickness of the coating can be freely controlled from thin to thick, saving the number of coatings and improving the powder spraying efficiency;

5. The powder spray coating is beautiful and durable;

6. It can be sprayed with a variety of colors.
