What do you know about the aluminum surface treatment process?

Metal materials are increasingly being used in various existing products, because the they can better reflect the product quality and highlight the brand value. In many metal materials, aluminum duue to its easy processing, good visual effect, rich surface treatment means, with various surface treatment processes, we are able to further tap the potential of aluminum alloy, giving it more function and more attractive appearance.

Aluminum Alloy

The surface treatment of aluminum profile is mainly divided into:

1. Sand blasting treatment

The process of cleaning and coarsening metal surfaces using the impact of high speed sand flow. The surface treatment of aluminum parts in this method enables the surface of the workpiece to obtain certain cleanliness and different roughness, to improve the mechanical properties of the workpiece surface. Thus improving the fatigue resistance of the workpiece, increased adhesion between it and the coating. Prolong the durability of the film, but also conducive to the flow of paint and peaceful decoration.

2. Anodic oxidation

It refers to the electrochemical oxidation of metals or alloys. Aluminum and its alloys under the corresponding electrolyte and specific process conditions. Due to the formation of an oxide film on the aluminum products (anode) under the action of the external current process. Anooxidation can not only solve the defects of aluminum surface hardness, wear resistance and other aspects, also prolong the service life of aluminum and enhance the aesthetics. It has become an indispensable part of aluminum surface treatment, is currently the most widely used and very successful process.

3. The brushing process

Is the manufacturing process of repeatedly scraping aluminum sheets with sandpaper. Brushing can be divided into straight wire, random wire, spinning wire and thread wire. Metal wire brushing process, can clearly show every tiny silk trace, that the metal matte in the general fine hair luster, the products have fashion and a sense of science and technology.

4. Electroplating process

Add a metal protective layer to the aluminum surface, improve the wear resistance, electrical conductivity and decoration of aluminum material. Electroplated aluminum parts can have the surface effect of various metals such as stainless steel, gold and silver.

5. Spray process

Let the aluminum surface presents a different texture and color. Whether it is the metallic sense of the shell paint, the multi-angle unreal color of the chameleon paint, or the imitation electroplating effect of electroplating silver coating, have greatly enriched the decorative effect of aluminum material.

The spraying process also includes rubber paint, conductive paint, UV oil, etc. Each coating brings different characteristics and visual effects to aluminum.

6. Printing process

It’s also an important part of the surface treatment of aluminum alloy. Laser engraving technology can leave fine patterns and text on the aluminum, with anti-counterfeiting function. Water transfer technology is suitable for complex shape of objects, can be transferred into natural patterns, such as wood grain, stone grain and so on.
