Forging: a workpiece or blank produced by forging a metal billet.The mechanical properties of metal billet can be changed by applying pressure to it to produce plastic deformation.

Forging features: large weight range, higher quality than the casting.Forgings are of better quality than rolling for high carbide steel.Minimum weight, saving raw materials.Precision forging forgings, not only can save more raw materials, but also can save more machining hours.

According to the forging temperature, the forging technology can be divided into hot forging, warm forging and cold forging.
