Centrifugal casting process - advantages and disadvantages

Centrifugal casting process

It is the method of producing castings where molten metal is poured into a  mould rapidly moving around a fixed axis. The molten metal come into contact with this rotating mould under a good amount of pressure because of the centrifugal force. This gives a better filling of mould. The casting grain density is also high.  As a result the porosity is almost zero. Centrifugal casting process is mainly used for making parts having the shape of bodies of revolutions.

Advantages of Centrifugal casting process :

i)           Castings acquire high density, high mechanical strength and fine grained structure

ii)                   Inclusions and impurities are lighter

iii)                 Gates and risers are not needed

iv)                 High output

v)                  Formation of hollow interiors without cores

 Disadvantages Centrifugal casting process:

i)                    An inaccurate diameter of the inner surface of the casting.

ii)                   Not all alloys can be cast in this way.

Applications of centifugal casting process:    

For casting pipe, bushings, gears, flywheel etc.
