It is not possible to reduce at one stage
Annealing is needed between stages
Accuracy in dimensions is not possible otherwise
Surface finish improves after every drawing stage
Is extensively used for making bolts and rivets
Is used for reducing the diameters of round bars and a tube by rotating dies which open and close rapidly on the work
Is used to improve fatigue resistance of the metal by setting up compressive stresses in its surface
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
