Is used to improve fatigue resistance of the metal by setting up compressive stresses in its surface
Is used for reducing the diameters of round bars and a tube by rotating dies which open and close rapidly on the work
Consists of pressing the metal inside a chamber to force it out by high pressure through an orifice which is shaped to provide the desired form of the finished part
Molten metal is forced into mould under high pressure
Molten metal is poured in a metallic mould, retained in the mould long enough for the outer skin to solidify and finally mould is turned over to remove molten metal still in molten condition
Molten metal is poured and allowed to solidify while the mould is revolving
