Forgings : Contour Rings

Forging is a metalworking process in which an impact device is used to deliver compressive force to areas of the metal in order to shape it. Forging was originally done manually with a hammer and anvil, however industrial forging machines now use hydraulics, compressed air, or other methods to drive mechanical hammers, or presses, into the surface. Contour rings are forged rings created by punching a hole through a round plate, or disk, of metal. Contour rings can be created with simple or complex counters on both the inner and outer diameters of the ring. Forged rings are characterized by high tangential strength and ductility.
