Centrifuging

In this process, several mould cavities are located around the outer portion of a mould, and the metal is fed to these cavities. The mould cavities are fed through radial gates provided from a central pouring reservoir by the action of centrifugal force (Figure 20.24). Relatively low rotational speeds are required to produce sound castings with thin walls and intricate shapes. This method is not limited to symmetrical objects but can produce castings of irregular shape such as bearing caps or small brackets.
