Make or shape (a metal object) by heating it in fire or furnace and beating or hammering it. Is a manufacturing process involves the shaping of metal using localized compressive forces.
Precisionforging normally means close-to- final form or close-tolerance forging. It is not a special technology, but a refinement of existing techniques to a point where the forged part can be used with little or no subsequent machining.
Precision forging and closed die forging have the basic same working principle. The difference is that precision forging has higher requirements on the surface, dimensional tolerances and shape. The precision forgings usually need less machining or without machining As a process of a one-time forming, precision forging need precision Size, weight and shape on forging blanks.
