2.0 CASTING PROCESSES

2.2 GENERAL ASPECTS OF CASTING PROCESS

1. Casting is a solidification process in which molten metal is poured into a mould and
allowed to cool.

2. Normally, the materials that used in casting processes is metal. Because a pure
metal has a clearly defined melting (or freezing) point, it solidifies at a constant

temperature.

3. The casting process basically involves:
a) pouring molten metal into a mould patterned after the part to be

manufactured;
b) allowing it to solidify;
c) removing the part from the mould.

4. Major factors affecting casting processes:
a) properties of mould such as shape, geometric, process etc.
b) properties of metal such as fluidity, solidification, surface etc.

5. Figure 2.2 shows example of casting product.

Another process that almost same as casting processes
Injection Moulding - Molten polymer injected into a mould while casting is a molten
metal poured into a mould.
