Molten metal is introduced into a rotating sand, metal, or graphite mould, and held against the mould wall by centrifugal force until it is solidified. Used for Hollow pipes, large bushings, gun barrels, etc.
Die casting:
It is a moulding process in which the molten metal is injected under high pressure and velocity into a split mould die.
Die casting is categorized two types namely -
- Hot chamber and cold Chamber.
- Metals like Zinc, tin, and lead alloys are cast in hot chamber die casting having melting point below 390°C whereas aluminum alloys are cast in cold chamber die casting machine.
Investment casting:
It is a process also called the lost-wax process begins with the production of wax replicas or patterns of the desired shape of the castings. These wax patterns are further destroyed to take out the final component hence they are also called an expendable patterns.
