1, free forging can improve the organization and properties of the metal, free forging can improve the quality and mechanical properties of the casting, its strength than the casting to improve 50% -70%. Therefore, it can withstand larger impact loads, the use of forgings can reduce the weight of the part itself under the premise of ensuring the design strength, which is important for aerospace and transportation.

2, forging can save raw materials. The use of free die forging process can be obtained with the workpiece shape similar to the parts.

3, free forging is suitable for single-piece small batch production, with a large variant of flexibility.

4, straight bending shaft parts and ring type parts due to the absence of transverse flow of metal layer, its flow distribution is generally more uniform than cast and forged parts. Especially suitable for simple shape, small changes in cross-section, axial flat straight line, crankshaft, disk, circle and other parts.

5, through the free forging process can meet some special torsion requirements, such as the use of reverse pull forging process, you can improve the quality of raw materials and so on.
