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.



Dongying Northeast Castings produces cnc machined closed pump impeller with controlled wall thickness, accurate mounting points, and consistent internal passages. Flexible materials and machining options support water, chemical, and industrial pump assemblies.
From tooling review to final inspection, our team manages casting, machining, surface treatment, and dimensional checks. OEM sizes and finishes are available for dependable pump housing production with practical lead times.
