What is Centrifugal Casting?

The centricast process consists of pouring molten metal into a steel rotating mould. Water cooling of the mould permits a fast solidification from the outside to the inside surfaces of the casting. After the solidification the item is pulled from the mould and is ready for heat treatment.


Here you can see some pictures showing the production cycle of a centricast pipe in A451 CPF8 (304).

 Centrifugal Casting Process Centrifugal Casting ProcessCentrifugal Casting Process 



Rotating MouldMolten MetalRotating MouldOxides and Impurities
Centrifugal Casting Process
Centrifugal Casting Process
Molten metal forced centrifugally against mould wall. Controlled solidification progresses inward towards the bore.Oxides and impurities concentrate in the bore and are removed by machining.



Why to choose centrifugal casting?

The centricast process produces:

  • Mechanical separation of non-metallic inclusions: microstructure cleanliness (improvement in performance). They will be eliminated during machining operation on inner bore.
  • High density of the material without shrinkage and gas porosities.
  • Very short lead time (rough condition: 2 weeks / pre-machined: 3-4 weeks ex. works).
  • All alloys can be produced (acc. to all international Standards).
  • Optimized and shaped mould to reduce weight and costs.
  • Mechanical properties higher than that of static castings and fully comparable with forgings.
  • Possibility to produce all possible size, not standard only, with weight and costs minimization.
