Surface treatment process of aluminum stamping parts

2021-12-07

For stamping factories, aluminum stamping parts are also a very common metal stamping part. Aluminum is light in weight, and products of the same size are relatively light, which can effectively reduce costs. Aluminum stamping parts generally require surface treatment to achieve some special work capabilities. Dongguan Fortuna has focused on precision metal stamping parts for more than ten years, and has accumulated rich experience in custom processing of stamping parts. Next, we will share some surface treatment methods of aluminum stamping parts, hoping to help everyone.

Aluminum stamping parts

1. Anodizing

When it comes to the surface treatment of aluminum stampings, anodizing process has to be mentioned. Anodizing can effectively make up for the lack of surface hardness and wear resistance of aluminum stamping parts, and can also greatly increase the use time of aluminum stamping parts, making the product look more beautiful. Now, anodizing has become a common surface treatment method for aluminum stamping products. Anodizing refers to the electrochemical oxidation of metals or alloys. Due to the action of the current applied under the corresponding electrolyte and specific process conditions, aluminum and its alloys form an oxide film on the aluminum product (anode).

2. sandblasting

Sandblasting is usually an intermediate process of surface treatment of aluminum stampings. After sandblasting, aluminum stampings can effectively remove surface burrs and oil stains. The surface of aluminum stamping parts can improve the cleanliness, and different surfaces can be obtained by controlling the sandblasting material. The roughness of the product. After sandblasting, the performance of the product can be greatly improved. In the subsequent surface treatment process, the adhesion between the aluminum stamping parts and the coating can also be increased, thereby making the product more durable and more beautiful.

3. polishing treatment

Polished aluminum stamping parts can be close to the mirror effect, which greatly improves the grade and aesthetics of the product. However, due to the characteristics of aluminum products, aluminum stampings are relatively less polished. If other surface treatments are not performed after polishing, the durability will be relatively low. After aluminum stampings are polished, it is difficult to maintain the mirror effect for a long time. Generally, it is recommended to use stainless steel for products that require a mirror effect.

4. wire drawing processing

There are many types of brushed aluminum stampings, the common ones are straight wire drawing, chaotic drawing, spiral drawing and thread drawing. After processing aluminum stampings by wire drawing, you can see clear and subtle traces on the surface, and the product gives a visual feeling of luminous silk grain.


Aluminum stampings basically require surface treatment after processing, but the choice of treatment method depends on the specific requirements of the customer.
