2.0 CASTING PROCESSES

2.5.10 SEMI-CENTRIFUGAL CASTING

1. An example of semi-centrifugal casting is shown in Figure 3.14.

2. This method is used to cast parts with rotational symmetry, such as a wheel with
spokes.

Figure 2.14 Schematic illustration of the semicentrifugal casting process.

2.5.11 CENTRIFUGING (CENTRIFUGE CASTING)

1. In centrifuging (also called centrifuge casting), mould cavities of any shape are
placed at a certain distance from the axis of rotation.
2. The molten metal is poured from the center and is forced into the mould by
centrifugal forces (Figure 2.15).

3. The properties of the castings can vary by distance from the axis of rotation, as in
true centrifugal casting.

Figure 2.15 Schematic illustration of casting by centrifuging. The moulds are placed at
the periphery of the machine, and the molten metal is forced into the moulds by centrifugal

force.
