Why do you need to use spray equipment to make aluminum profiles?
The aluminum profiles types can be divided into: anodized colored profiles, electrophoretic painted profiles, powder coated profiles, fluorocarbon paint spray profiles, and thermal insulation profiles. The aluminum alloy is an aluminum material is formed by a hot melt and an extrusion to obtain a different cross-sectional shape. The production process of aluminum profiles are provided by three processes of casting, extrusion and coloring.
Aluminum is a light metal with a silver-white luster, and its corrosion resistance has the following two characteristics:
1. The higher the purity, the better the corrosion resistance. It is well known that pure aluminum reacts with oxygen in the air, and a very thin and dense natural oxide film is produced on the surface of aluminum, which is faster than other metal Oxide films. It is thicker, thus preventing the corrosion of harmful gases and moisture in the air and protecting it;
2. The corrosion resistance of pure aluminum is good, but the mechanical strength is poor, which restricts the application of aluminum to a certain extent. The aluminum alloy has high mechanical strength, the corrosion resistance is inferior to that The aluminum alloy has been widely used in doors, windows and curtain walls of buildings for many years due to its small specific gravity, Easy processing and high mechanical strength. ,

After powder coating, aluminum profiles have many advantages such as high corrosion resistance, diversified colors, good surface texture, etc. Regarding why the aluminum profiles are used in the manufacturing process, I hope to help you if you need spraying equipment, please call us Or consult our online customer service
