Casting (founding) is the process of producing solid objects by pouring molten material into a shaped mould and allowing it to cool.
Casting is used to shape such materials as glass and plastics, as well as metals and alloys. The casting of metals has been practiced for more than 6,000 years, using first copper and bronze, then iron. The traditional method of casting metal is sand casting. Using a model of the object to be produced, a hollow mould is made in a damp sand and clay mix. Molten metal is then poured into the mould, taking its shape when it cools and solidifies. The sand mould is broken up to release the casting. Permanent metal moulds called dies are also used for
casting, in particular, small items in mass-production processes where molten metal is injected under pressure into cooled dies. Continuous casting is a method of shaping bars and slabs that involves pouring molten metal into a hollow, water-cooled mould of the desired cross section. Research Casting
