Instead of Casting material body, forged material is produce by way that use forging machinery to the press metal blank, to make the metal plastic deformation, to obtain material with certain mechanical properties, a certain shape and dimension.
Forging material one of the two major components. By forging can eliminate the casting of metal as loose, welding holes, forging mechanical properties are generally better than the same material castings. To produce important part used in heavy load in the machine, and strick working conditions, if the part chape is easy, can use shape material, profiles material and welding parts; it uses forging material for rest part.
