Forging an old and is in the flourishing of development of a metal processing technology. At present, human production of most metals are ultimately after forging methods processed into finished parts. Forging plastic processing is an important branch, which is the use of plastic material, the role of outside help produce plastic deformation, obtain the necessary shape, size and performance of certain organizations forgings. Any process of forging a fundamental purpose is to be consistent with the requirements of the contour drawings, the internal organization of the size and performance of qualified forgings. A perfect die design process, according to the first parts of the shape and size of forging design. Forging choice step is the key. Determining step, in accordance with the design of heat forging die barrels, die and trimming. In the design process, the need to hammer calculation to determine the tonnage of raw materials and the volume (both for the next material).
