Forging is a processing method that uses forging machinery to exert pressure on metal blank to make it produce plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes. Forging (forging and stamping) is one of the two major components. Forging can eliminate as cast porosity and other defects produced in the smelting process of metal, optimize the microstructure. At the same time, due to the preservation of complete metal streamline, the mechanical properties of forgings are generally superior to castings of the same material. For important parts with high load and severe working conditions in related machinery, forgings are mostly used, except for simple rolled plates, profiles or weldments.

What are the requirements for the materials used for forged parts?
The materials for forgings are mainly carbon steel and alloy steel of various compositions, followed by aluminum, magnesium, copper, titanium, etc. and their alloys. The original state of materials includes bar stock, ingot, metal powder and liquid metal. The ratio of cross sectional area of metal before deformation to that after deformation is called forging ratio. The correct selection of forging ratio, reasonable heating temperature and holding time, reasonable initial and final forging temperature, reasonable deformation amount and deformation speed have a great relationship to improve product quality and reduce cost.
In modern pressure processing, for the production of large round forgings, roll rolling mill (reamer) can be used for roll forging forming, which has the advantages of accurate size, high production efficiency, good quality of forgings, etc. In the absence of production conditions for roll forging, it can be formed by expanding holes on a free forging hammer or hydraulic press with a horse stand.
