Product Description

The forging process is generally composed of the following procedures, namely selecting high-quality billet feeding, heating, forming, and cooling after forging. The forging process includes free forging, die forging and membrane forging. Production, according to the size of the forging quality, the number of production batch choose different forging methods.

Free forging has low productivity, large processing allowance, but simple tools and large versatility, so it is widely used for forging single and small batch forgings with simple shape. Free forging equipment includes air hammer, steam - air hammer and hydraulic press, which are suitable for small, medium and large forging production respectively. 

Die forging has high productivity, simple operation, easy to realize mechanization and automation. The die forging has high dimensional accuracy, small machining allowance and more reasonable distribution of fiber structure, which can further improve the service life of parts.
