Metal Casting-
Casting is the oldest and perhaps the most popular mean of producing the desired shape. The final product or the casting can be made from any metal that can be melted and have virtually any configuration. Castings have been produced in sizes varying from few millimeters to several meters and can weight from few grams to several tons.
The process basically involves melting and superheating the raw material up to the desire temperature. The molten metal is then allowed to solidifying in the mould cavity and on cooling, the product is taken out to get the casting. Several casting processes have been developed over the years - each having its own characteristics, applications, advantages and limitations.
