Customized high quality metal aluminum sheet metal stamping parts

The aluminum alloy anodizing process is a treatment process that produces an artificial oxide film on the surface of aluminum or aluminum alloys. This oxide film can improve the corrosion resistance, wear resistance and decorative properties of aluminum and aluminum alloys. The following are the main steps of our aluminum alloy anodizing process:

First, put the aluminum or aluminum alloy product into the anodizing tank to ensure that the surface of the aluminum plate is in good contact with the electrode of the treatment tank.
Then according to the required properties of the oxide film, select the appropriate electrolyte, such as sulfuric acid, oxalic acid, chromic acid, etc. At the same time, adjust the temperature, concentration and other parameters of the electrolyte as needed.
By applying DC power, the aluminum or aluminum alloy is electrolytically reacted in the anodizing tank. During the electrolysis process, an oxide film will form on the surface of aluminum or aluminum alloys.
Then the anodizing time is controlled according to the required thickness of the oxide film. Generally speaking, increasing the anodizing time can increase the thickness of the oxide layer. At the same time, by adjusting parameters such as current density, the thickness and properties of the oxide film can also be controlled.
Finally, the anodized film can be colored, which is divided into two methods: electrolytic coloring and chemical coloring. By adjusting the type and concentration of colorants, oxide films of different colors and textures can be obtained.
Finally, the anodized or colored aluminum or aluminum alloy is sealed. Sealing treatment can seal the micropores in the oxide layer and improve the corrosion resistance and sealing performance of aluminum or aluminum alloys.
During the entire process, the process parameters and quality requirements of each process need to be strictly controlled to ensure that the final aluminum alloy anodized products produced have good performance and quality. In addition, attention must be paid to operational safety to avoid electrolyte harm to the human body and the environment.

This process is widely used in the construction field and machinery manufacturing industry. In the construction field, anodized aluminum alloys can be used to manufacture curtain walls, windows, doors, etc. to improve their weather resistance and decorative properties. In the machinery manufacturing industry, anodizing treatment can improve the wear resistance and service life of aluminum alloy parts.
The aluminum alloy anodizing process is an important surface treatment technology. By controlling the process parameters and processes, aluminum alloy products with excellent properties can be obtained.
