Several common surface treatment processes for aluminum stamping parts in hardware stamping factories

Briefly describe several common surface treatment processes for aluminum stamping parts in hardware stamping factories:

1. Aluminum anodizing

When it comes to the improvement of the surface treatment of aluminum stamping parts, it is inevitable to mention the anodizing process. Anodizing can effectively compensate for the surface hardness and wear resistance of aluminum stamping parts, and greatly increase the service life of aluminum stamping parts, making the product look more beautiful. Nowadays, anodizing has become the most common and common surface treatment method for aluminum stamping products. Anodizing refers to the electrochemical oxidation of metals or alloys. Aluminum and its alloys form an oxide film on aluminum products (anodes) under the action of external current in corresponding electrolytes and specific process conditions.

In addition, aluminum stamping parts can also be anodized to obtain various colored appearances, further expanding the use of aluminum stamping parts.

2. Sandblasting

Sandblasting is generally the central process for the surface treatment of aluminum stamping parts in hardware stamping factories. Sandblasting aluminum stamping parts can effectively remove burrs and oil stains on the surface, improve the cleanliness of the aluminum surface, and obtain products with different surface roughness by controlling the sandblasting material. After sandblasting, the product's functionality can be significantly improved. In the subsequent surface treatment process, it is also possible to add adhesion between aluminum stamping parts and coatings, making the product more durable and beautiful.

3. Polishing

The polished aluminum stamping parts can have a mirror like effect, greatly improving the quality and beauty of the product. However, due to the characteristics of aluminum products, polishing of aluminum stamping parts is relatively rare. If no other surface treatment is done after polishing, the durability will be relatively low. It is difficult to maintain the mirror effect of aluminum stamping parts for a long time after polishing. Generally, products that require mirror effect are recommended to use stainless steel.

4. Wire drawing processing

There are many types of drawing for aluminum stamping parts, including straight drawing, random drawing, spiral drawing, and thread drawing. After drawing, clear and subtle traces can be seen on the surface of the aluminum stamping parts, giving the product a glowing silk like feeling.

Basically, aluminum stamping parts require surface treatment after processing, but the choice of treatment method depends on the specific requirements of the customer. In the absence of customer requirements, Metal Stamping factories generally choose anodizing.
