Forging is one of the two components of forging (forging and stamping).

Through forging, it can eliminate the defects such as the porosity of the cast state generated in the process of smelting, optimize the microstructure and structure, and the mechanical properties of forgings are generally better than castings of the same material due to the preservation of complete metal streamline. For the important parts with high load and severe working conditions in related machinery, forging is often used, except for the plate, profile or welding parts with simple shape that can be rolled.
