Metal surface treatment has a wide range of applications in industrial production. Below are a few specific examples to illustrate:

1. Automobile manufacturing: Automobile is a representative of metal products, and its surface treatment has a significant impact on the quality and appearance of automobiles. The commonly used metal surface treatment methods in automobile manufacturing include sandblasting, acid pickling, electroplating, electrophoretic coating, etc.

2. Electronic manufacturing: The metal shell in electronic products needs to undergo surface treatment before undergoing painting, screen printing, and other processes to improve the decorative performance and corrosion resistance of the product. The commonly used metal surface treatment methods in electronic manufacturing include anodizing, sandblasting, electroplating, etc.

3. Mechanical manufacturing: Metal parts in mechanical manufacturing require surface treatment before assembly and use. Surface treatment can remove scale and dirt, improve the corrosion resistance and mechanical properties of metal parts. The commonly used metal surface treatment methods in mechanical manufacturing include polishing, pickling, electroplating, sandblasting, etc.

4. Architectural decoration: Metal products in architectural decoration require surface treatment before painting and installation. Surface treatment can improve the decorative performance and corrosion resistance of metal products. The commonly used metal surface treatment methods in architectural decoration include anodizing, electroplating, sandblasting, etc.

In short, metal surface treatment has a wide range of applications in industrial production, which can improve the quality and performance of products and provide strong support for the development of various industries.
