The process of drawing aluminium sheet is very simple. Under the action of external force, the aluminium sheet passes through the die forcibly. The cross-sectional area of metal is compressed and the required cross-sectional area shape is obtained. This process represents the drawing process of aluminium sheet. The main process of making aluminium sheet is degreasing, sand mill and water washing.
After finishing the drawing process, the aluminium sheet is anodized, which can form an oxide film on the surface of the aluminium sheet. Anodic oxidation process: one degreasing ~water washing ~alkali corrosion ~water washing ~neutralization and one water washing anodic oxidation water washing one hole one water washing one rack one detection one packaging. Degreasing, alkali corrosion, neutralization, anodic oxidation, sealing and other processes in the process are the key to ensure the quality of oxidation treatment. This process can make the surface of drawing aluminium sheet clearly show every tiny trace. Eventually, the fine silky luster of the matte metal can be exuded. Nowadays, more and more products adopt drawing aluminium sheet, which can play a very good aesthetic role, as well as anti-corrosion role.
Oxidized drawing aluminium sheet is not only colorful and fashionable in appearance, but also excellent in performance. It is a new decorative environmental protection material with high practicability.
