Low-Carbon Steel Shot & Grit Lead the Upgrade of Casting Cleaning, Empowering the Improvement of Auto Parts Quality

2026-03-06

As high-efficiency metal abrasives, steel shot and Steel Grit are increasingly widely used in casting and foundry production, especially playing a core role in the cleaning of auto parts castings, driving the industry towards refinement and high efficiency.

For core auto parts castings such as engine blocks and cylinder heads, sand adhesion, scale and other impurities are likely to remain during production, affecting product performance and subsequent processing. With the advantages of high hardness and high wear resistance, steel shot and steel grit can comprehensively clean hidden parts such as inner cavities and narrow water channels by spraying the surface of castings at high speed through shot peening technology. They can not only completely remove impurities and reveal the metallic luster, but also strengthen the surface of castings and improve their fatigue resistance and service life. Among them, our low-carbon steel shot performs particularly prominently with better cleaning effect, which can polish the casting surface to a bright finish, further improving the appearance texture of castings and the adhesion of subsequent coating.

Compared with traditional cleaning methods, the cleaning efficiency of steel shot and steel grit is increased by more than 30%, and they can be recycled, which greatly reduces the production cost and environmental pressure of enterprises, and adapts to the mass production demand of auto parts. At present, most domestic auto casting enterprises have popularized this process, effectively improving the qualification rate and production efficiency of parts.
