What is casting?
The casting process is used to make complex shapes by pouring molten metal into a mould. Parts that would be difficult or uneconomic to make by other methods can be produced by casting. Castings are produced from re-cycled metal and in this way the casting process is able to take a waste product and turn it into new high value components, unendingly. The process offers unlimited scope in design.
In diecasting, the mould is made of metal and is called a tool or die. The molten metal is introduced into the die by gravity or under low pressure or high pressure. The die may be re-used many thousands of times to produced thousands of components.
