2.0 CASTING PROCESSES

Figure 3.12 Various types of cavities in a die-casting die.

Example 2.3:

Describe the differences between hot-chamber and cold-chamber die casting
processes respectively.

Solution:

Hot-chamber die casting Cold-chamber die casting

Implementing high temperature. Use normal temperature.
Suitable for low melting point alloys such Suitable for high melting point alloys such
as zink, magnesium, lead and tin. as aluminum, magnesium and copper.

2.5.8 CENTRIFUGAL CASTING

1. Centrifugal-casting process utilizes inertial forces (caused by rotation) to distribute
the molten metal into the mould.
2. There are three types of centrifugal casting:
a) True centrifugal casting.
b) Semi-centrifugal casting.

c) Centrifuging.
