It is one kind of pressure processing.
It is a processing method which use forging machinery to put pressure on metal blank, so as to produce plastic deformation, to get forged piece which has some mechanical performance, certain shape and size. Forged press (forging and pressing) is one of the two major parts. Through the forging can eliminate as-cast defects such as osteoporosis that is produced in the metal smelting process, optimization micro structure, at the same time as the complete preservation metal flow line, the mechanical properties of the forged piece is general better than the same material castings. Important parts with high load and working conditions severe  in related machinery, in addition to the rolling plate, the profiles which can be used or rolling welding parts with simple shape, more used forgings.
