Centrifugal Casting Process

Main features

Transfer of liquid metal into a rapidly rotating casting mold The Centrifugal Casting (or spun casting) process in metallic tooling under very high acceleration, produces a casting using centrifugal pressure. This pressure creates, within the alloy, a very important degassing, which rejects all the impurities, potentially contained in a liquid metal melt, towards the bore.

The one-direction cooling and solidification of the alloy are perfectly controlled.

Vertical centrifugal casting (or vertical spun casting)
Heavy parts, whose diameter is generally more important than the length, are produced using vertical centrifugal casting machines.

Horizontal centrifugal casting (or horizontal spun casting)
Long parts are produced using horizontal centrifugal casting machines.

Main advantages

View of the opening of a centrifugal casting processYou can obtain alloys which are/have:

  • Fine structured,
  • Sound and compact,
  • Perfectly homogeneous,
  • Free from blowholes and inclusions,
  • Very high mechanical properties (the highest you can obtain by any foundry process).

Parts produced are:

  • Easily machined,
  • Free from any distortion,
  • Enhanced resistance to corrosion and wear.

The combination of induction melting and centrifugal casting (or spun casting) process leads especially, as far as austenoferritic steels are concerned, to very high quality levels, similar to those obtained on parts cast under vacuum or with AOD converter.
