What are the advantages of surface treatment technology for water pump castings

In today's industrial production, the surface treatment technology of water pump castings has received increasing attention. Ningbo Andrew relies on its profound accumulation and technological innovation in this field to actively apply a variety of advanced surface treatment technologies to improve product performance and service life.

The surface treatment technologies used by Ningbo Andrew include sandblasting, electroless nickel plating, electroplating chromium and anodizing. These technologies not only effectively remove oxide scale, oil stains and other impurities on the surface of castings, but also significantly improve the surface hardness, corrosion resistance and wear resistance of castings, thereby extending the service life of the water pump.

Sandblasting is an important method for surface treatment of water pump castings. The impact of high-speed sand particles on the surface of the casting can effectively remove surface dirt and rust, making the surface of the casting reach ideal cleanliness and smoothness. In addition, sandblasting can also increase the roughness of the casting surface, thereby enhancing the bonding force between the coating and the casting. Ningbo Andrew's investment in sandblasting equipment and technology ensures the stability and consistency of the treatment effect.

Electroless nickel plating technology can form a dense coating evenly on the surface of castings because it does not require an external power supply. This coating not only has excellent corrosion resistance and wear resistance, but also significantly improves the surface hardness and gloss of the casting. Ningbo Andrew has reached the industry-leading level in the application of electroless nickel plating technology and can meet customers' strict requirements for the surface quality of castings.

Electrochromium plating technology is another important method in the surface treatment of castings. By forming a hard chromium coating on the surface of castings, it significantly improves the wear resistance of water pump castings. This coating not only provides extremely high hardness, but also enhances the corrosion resistance and decorative properties of the casting. Ningbo Andrew has advanced equipment and processes in electroplating chromium technology and is able to provide customers with high-standard electroplating chromium services.

Anodizing technology forms an oxide film on the surface of castings through electrolysis, giving castings excellent corrosion resistance and wear resistance. This oxide film significantly improves the corrosion resistance and service life of the water pump casting. In the application of anodizing technology, Ningbo Andrew focuses on the stability of the process to ensure that it provides customers with high-quality anodizing services.

In terms of strict quality control, Ningbo Andrew always puts product quality first. The company is equipped with advanced testing equipment, including microscopes, hardness testers and corrosion resistance testing machines, to conduct comprehensive testing of the surface quality of castings. At the same time, Ningbo Andrew has established a complete quality management system to monitor and record the entire surface treatment process to ensure the traceability of product quality.
