Brass castings with different finishes: the perfect combination of beauty and functionality

In modern industrial manufacturing, brass castings are widely used in various machinery manufacturing fields, and their excellent mechanical properties and good processing properties make them very popular. In order to meet the needs of different customers, our company, NINGBO JH Metal Technology Co., Ltd., is committed to providing a variety of surface treatment options to meet customers' needs for appearance and functionality.

polishing:
Polishing is one of the most common surface treatment methods, which uses mechanical or chemical means to make the surface smooth and flat. For brass castings, polishing can not only enhance their appearance and texture, but also improve their corrosion resistance and extend their service life. The surface of polished brass castings is as smooth as a mirror, showing a charming metallic luster, and is suitable for high-end decorations, precision instruments and other fields.

Electro-galvanizing:
Electro-galvanizing is a common surface treatment method that improves the corrosion resistance of brass castings by plating a layer of zinc on the surface. Electro-galvanizing can not only effectively prevent brass castings from losing their luster due to oxidation, but also make the surface smoother and more uniform, with good oxidation resistance. This surface treatment is suitable for outdoor equipment, automotive parts and other products that require long-term exposure to harsh environments.

Sand blasting and shot blasting:
Sand blasting and shot peening are commonly used surface treatment methods. By spraying abrasive particles at high speed, the oxide layer and impurities on the surface of brass castings are removed, thereby increasing its surface roughness and improving coating adhesion. The surface roughness of brass castings after sand blasting and shot peening is moderate, which not only retains the texture of the metal, but also has good coating adhesion. It is suitable for products that require subsequent painting or coating treatment.

Silica sol casting:
Silica sol casting is a high-precision casting process. The parts in contact between the mold and the casting liquid are filled with silica sol, so that very detailed and precise surface details can be obtained. For brass castings, silica sol casting can achieve extremely high dimensional accuracy and surface finish, and is suitable for products requiring high precision and complex structures.

Through the above different surface treatment methods, our company can meet the diverse needs of customers for the appearance and performance of brass castings. Whether you are pursuing exquisite appearance or functional performance, we can provide customers with the best solutions to add more competitiveness to their products.
