Centrifugal Casting Parts
What Is Centrifugal Casting?
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.
When To Use Centrifugal Casting
Centrifugal casting is a good choice when your application requires:
-
Symmetrical shapes such as tubes, rings, and cylinders
-
Improved material properties over sand casting
-
Eliminating centerline shrinkage to improve structural integrity
-
-
Large parts up to 125,000 lbs. (56 700 kg)
-
Uniform grain structure for enhanced strength and performance
-
High dimensional integrity for applications such as defense
