Rotary swaging
1
is extensively used for making bolts and rivets.
2
is used for reducing the diameters of round bars and tubes by rotating dies which open and close rapidly on the work.
3
is used to improve fatigue resistance of the metal by setting up compressive stresses in its surface.
4
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.
