What is centrifugal casting?

Centrifugal casting is a method where a permanent mold is rotated continuously about its axis at high speeds as the molten metal is poured. The molten metal is centrifugally thrown towards the inside mold wall, where it solidifies after cooling. The casting is usually a fine grained casting with a very fine grained outer diameter, owing to chilling against the mould surface. Impurities and inclusions are thrown to the surface of the inside diameter, which can be machined away.

 

 

 

 

 

Advantages of Centrifugal Casting

Parts and pipes can be cast without cores

 

The mechanical properities are superior to other casting methods due to non porous and clean microstructure

 

Tight dimensional tolerances and high quality surfaces

 

A wider range of alloy possibilities

 

It is possible to cast thin walled cylinders

 

Pouring temperature can be low due to high feed rate

 

Elimination of negative environmental effects created by the sand and additives

 

High efficiency levels are achieved with less energy consumption
