Is the process by which metal is heated and is shaped by plastic deformation by suitably applying compressive force, Usually the compressive force is in the form of hammer blows using a power hammer or a press.

Forgings are consistent from piece to piece, without any of the porosity, voids, inclusions and other defects. Thus, finishing operations such as machining do not expose voids, because there aren't any. Also coating operations such as plating or painting are straightforward due to a good surface, which needs very little preparation
