Workshop Technology
Rotary swaging

Is used for reducing the diameters of round bars and a tube by rotating dies which open and close rapidly on the work

Is extensively used for making bolts and rivets

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
