Centrifugal Casting

With generations of experience in the cast metal and foundry industry, Kormax brings a long history of providing quality engineering materials and the expertise needed for your next project.

Centrifugal Casting

Centrifugal casting, also known as spin casting or centrifugal die casting, is a metal casting process used to create hollow cylindrical components. In this method, molten metal is poured into a rotating mould, which can accommodate profiles up to 236”/6000 mm in diameter. The centrifugal force generated by the spinning mould forces the metal outward against the mould walls, resulting in a dense, fine-grained casting. Impurities are naturally pushed toward the centre of the casting, making them easy to machine out later. This process ensures that centrifugally cast materials are close-grained and defect-free, offering superior hardness, strength, and ductility. These qualities make centrifugal casting ideal for high-reliability applications that require enhanced performance, such as jet engine compressor cases, engine cylinder liners, and bushings. With over 75 years of expertise, Kormax has mastered this process to deliver high-quality components that meet the demanding needs of various industries.

Centrifugal Casting Process: How Does Centrifugal Casting Work?

Building on our understanding of centrifugal casting, let’s explore the detailed process that ensures precision and quality in every casting:

  • Mould Preparation: A cylindrical mould is prepared and coated with a refractory lining to withstand high temperatures and prevent the molten metal from adhering to the mould surface.
  • Rotation Initiation: The mould is set to rotate at a specific speed, generating the centrifugal force needed to evenly distribute the molten metal.
  • Pouring: Molten metal is carefully poured into the rotating mould. The centrifugal force causes the metal to spread uniformly and adhere tightly against the mould walls.
  • Solidification: As the mould continues to spin, the metal cools and solidifies from the outer surface inward, resulting in a fine-grained structure with minimal defects.
  • Cooling: The casting is allowed to cool completely while still rotating to maintain dimensional accuracy and structural integrity.
  • Removal: Once cooled, the rotation is stopped, and the solidified casting is carefully removed from the mould.
  • Machining: Any impurities or excess material at the centre are machined out, achieving precise dimensions and a smooth finish.

At Kormax, we have perfected this process, producing high-quality centrifugal castings that meet your specific project needs. Our expertise ensures each step is executed with precision, delivering components that perform reliably in even the most demanding applications.
