We manufacture precision cast threaded pump covers with accurate threads, stable dimensions, and clean sealing faces. Each part is inspected for fit, finish, and dependable use in pump assemblies.
Our foundry specializes in centrifugal gravity casting, a precision manufacturing process that produces high-strength, defect-free metal and steel components. This method utilizes centrifugal force to distribute molten metal evenly into sand molds, ensuring superior density, fine grain structure, and enhanced mechanical properties. Ideal for machinery parts requiring durability and dimensional accuracy, our process minimizes porosity and inclusions, resulting in reliable performance under heavy loads and harsh conditions.
We offer customized sand casting solutions for industrial machinery parts, including gears, housings, pulleys, and valve bodies. Using high-grade steel and alloy materials, we cater to sectors like automotive, mining, and heavy equipment manufacturing. With strict quality control, advanced metallurgical expertise, and competitive lead times, we deliver cost-effective casting solutions tailored to your specifications. Contact us for durable, high-performance cast components that meet your engineering demands.

Centrifugal casting is the preferred metal casting process for applications demanding high strength and reliability, such as flight and land-based turbine engine compressor cases, petrochemical furnace tubes and reformer tubes, and naval defense components. Centrifugal casting produces defect-free parts with excellent material integrity.
In centrifugal casting molten metal is poured into a spinning die, which rotates on a vertical or horizontal axis depending on the part's design. Vertical centrifugal casting is commonly used for rings and cylinders, while horizontal centrifugal casting is ideal for tubes. Each can yield multiple parts from a single casting, increasing efficiency.
Intense centrifugal force pushes denser metal to the outer diameter (O.D.) and drives impurities and oxides toward the inner diameter (I.D.), where they can be removed by machining. Directional solidification under pressure ensures a uniform structure, preventing mid-wall shrinkage and eliminating defects such as gas pockets or cavities.
