Process flow of aluminum profiles:

Substrate - Hanging - Degreasing - Overalkali/Acid - Neutralization - Anodizing - Coloring - Sealing - Washing - Drying - Inspection - Packaging - Shipping

Division explanation:

1. Base material: The company currently uses GB6063 aluminum material, which has high conductivity, thermal conductivity, and ductility. Aluminum is a very active chemical element that is soluble in both acids and alkalis. It is a typical binary substance that forms a protective film under natural conditions.

2. Sandblasting treatment, surface secondary treatment, refining the surface stretch lines of the profile, covering acceptable defects, and oxidation is aimed at refining the surface micropores of the profile.

3. Hanging, select different hanging tools based on different products, sizes, shapes, and requirements. Hanging is important to ensure conductivity.

4. Degreasing, aluminum profile manufacturers aim to remove industrial lubricating substances and oil and impurities attached to the surface of aluminum profiles, ensure uniform alkaline corrosion of profiles, and ensure the cleanliness of alkaline corrosion grooves; Improve the surface treatment quality of aluminum profiles.

5. Alkali corrosion, the purpose of which is to remove residues and metamorphic layers on the surface of aluminum profiles during the oxidation process, as well as the characteristics of aluminum profiles, and to eliminate scratches and defects left on the surface of aluminum profiles during the extrusion process; In order to improve the surface effect of some products, acid etching is used first. Acid etching is to remove the naturally formed oxide film on the surface, and it needs to be washed immediately after treatment.

6. Neutralization, residual alloy elements or impurities such as copper, manganese, iron, silicon that are insoluble in alkaline solutions on the surface after acid and alkali corrosion treatment.
