Zinc alloy die casting surface treatment technology continues to innovate to improve product performance

In modern industrial manufacturing, zinc alloy die castings are a common material, and their surface treatment technology has always been the focus of attention. Recently, innovative technologies for surface treatment of Zinc Alloy Die Castings have been emerging, opening up new possibilities for improving product performance.

1. Electroplating technology: improve hardness and corrosion resistance

In the traditional electroplating process, Zinc Alloy Die Castings are often plated with nickel on the copper base layer and then treated with chromium. This process not only increases the hardness and wear resistance of the casting, reduces the friction factor, but also improves corrosion resistance. In addition, direct chrome plating is also used to further improve product performance.

2. Painting process: various paint applications

Painting is another common surface treatment, and Zinc Alloy Die Castings can be coated with a variety of different paints. Prior to painting, workpieces are typically treated with a phosphate or chromate solution to ensure coating adhesion and surface quality.

3. Metal spraying: simulate the appearance of various metals

Metal spraying technology is a highly innovative process that applies an extremely thin metal film to the surface of the processed parts in a high vacuum environment. This method can simulate a variety of appearances such as copper, silver, brass, gold, etc., and is especially suitable for processing die castings.

4. Anodizing treatment: improve corrosion resistance

Anodizing is an effective process to improve the corrosion resistance of Zinc Alloy Die Castings. Anodizing oxidation treatment at a voltage not exceeding 200V forms a protective film on the surface of the product to enhance corrosion resistance.

These innovative surface treatment technologies not only improve the performance of zinc alloy die castings, but also expand their application scope in different fields. Continuous progress and technological innovation in manufacturing will bring more durable and high-performance products to various industries.
