Introduction to Surface Treatment Methods for Aluminum Die Casting Processing
The customized surface treatment for aluminum die-casting processing is aimed at improving its appearance, mechanical properties, and corrosion resistance. The following is an introduction to several common surface treatment methods for aluminum die-casting products:
1. Electroplating: Electroplating is a process of depositing metal ions on the surface of conductors, which can improve the corrosion resistance and decorative effect of aluminum die-casting processing machinery. Usually nickel, chromium, copper and other metals are used for electroplating.
2. Oxidation: Oxidation is a surface treatment method that utilizes an oxidation reaction to form an oxide film on the surface of aluminum. This oxide film can improve the corrosion resistance and decorative effect of aluminum die-casting products. The commonly used oxidation methods include sulfuric acid oxidation, sulfuric acid chromic acid oxidation, and nitric acid oxidation.

3. Sandblasting: Sandblasting is a surface treatment method that uses high-speed jet flow to impact fine sand or other particulate matter onto the surface of aluminum, thereby changing its surface morphology and smoothness. Sandblasting can increase the friction coefficient and adhesion of aluminum die-casting products.
