The structure and mechanical performance of metals could be improved after the metals are forged. The Fork toe could make the original bulky dendritic and columnar grain to be of grain organization, with the help of the deformed metal and the recrystalizing process. Such grain is quite uniform and identical in size, which make the original segregation, porosity, and slag in the steel pieces compact and welded. The organization would be much closer, with improvements on the plasticity and mechanical property of the metal.
 
Forging parts are made with pressure posed by metals. The required shape and suitable compression force are met in the plastic deformation. Such force is realized with the usage of iron hammer and pressure. Accurate grain structure is maintained in the forging process. Besides, the physical property of metal is greatly improved. In the real use of spare parts, a correct design could make the grain flow oriented towards the direction of the main pressure.
 
Forging parts supplier companies may eliminate many obstacles about metal in the forging process, such as obstacles of loose forging in the whole process. The minimum organization and structure of the metal forging parts would be optimized in this process. The forging parts would have better mechanical property than average casting pieces in that complete metal lines are maintained. Therefore, forging parts are used under most circumstance in the environment of high loading pressure and harsh environment, except for the board, wood and welding parts of simple forms.
 
Metal forging companies need to pay attention to several points in the forging process. The blank and the material should not be restricted, so that the sizes of the blank and the material should be well under control. The relevant location of the forging molds and the forging parts should be measured carefully, so as to reduce the friction of the forging molds as much as possible. In order to maintain high delicacy of the forging parts, workers should pay attention to avoid overload at the bottom point as well as control the speed and location of the forging molds. Nowadays, the forging process is controlled by computers to large extents. The movement of the forging molds and the Forging parts are controlled by computers to attain complicated products of high delicacy with relatively low forging force. For example, forging parts such as automobile leave parts of diversified types and large sizes could be produced.
