The tools and equipment used for free forging are simple, versatile and low cost. Compared with the casting blank, free forging eliminates shrinkage cavity, porosity, porosity and other defects, making the blank have higher mechanical properties. The forging is simple in shape and flexible in operation. Therefore, it has a special significance in the manufacture of heavy machinery and important parts.

Free forging controls the shape and size of forgings by manual operation, so the forging has low precision, large machining allowance, high labor intensity and low productivity. Therefore, it is mainly used for single piece and small batch production.
