There are many kinds of surface treatment methods for die-cast aluminum. Which process method to choose to process die-cast aluminum alloy depends on the quality requirements of the product. The following Die Casting Supplier will introduce the current more common surface treatment methods:

1. If the surface quality requires aluminum alloy metal color, polishing or passivation anti-corrosion protection treatment process can be used;

2. If there is no requirement for the natural color of aluminum alloy metal on the surface, cleaning or passivation anti-corrosion protection treatment process can be used;

3. If the surface needs a variety of decorative effect colors, cleaning, passivation, painting or electrophoresis can be used;

4. If the surface needs to be protected by plating metal, cleaning and electroplating can be used;

5. If the product has relatively high requirements for corrosion resistance, it can be cleaned, activated, passivated, or passivated followed by sealing and spraying treatment;

6. At present, the die-cast aluminum treatment in the industry also uses metal conductive oxidation treatment.
Through the above introduction, Zinc Die Casting Manufacturers hopes that you can simply refer to the content of this article in future use.
