Centrifugal Castings


Centrifugal Castings

Centrifugal casting is a process that delivers shaped castings very near to the final dimension and of high material soundness. It is the best choice for the production of critical components where a high grade of reliability is required.

In the centrifugal casting process, liquid steel is poured into a spinning metallic shaped mould. Centrifugal action leads to:

  • Mechanical separation of inclusions and impurities towards the internal surface, that will then be removed through the machining process, ensuring high metallurgical cleanliness.
  • Extremely rapid directional solidification of molten steel under the pressure generated by centrifugal force that results in a very fine and defect free microstructure which produces outstanding mechanical properties and corrosion resistance.
  • High process versatility and the ability to produce small quantities (single castings) ensures very short lead times.
  • Possibility to pour items with tailored chemical analysis.
  • Production of components difficult to be forged due to their poor cold or hot formability, with particular focus on heat resistant alloy products with high carbon levels.
