open die forging

2022-03-17

Open die forging is the full name of open die forgin is the use of impact force or pressure to make the metal in all directions between the anvil surface free processing deformation, without any restrictions to obtain the required shape and size and a certain mechanical properties of forging a processing skill, referred to as open die forging. The tools and equipment used inopen die forging are simple, universal and low cost. Compared with casting blank, open die forging eliminates shrinkage cavity, shrinkage porosity, porosity and other defects, so that the metal blank has higher mechanical properties. Free forging is operated by the forging hammer or press (mostly hydraulic press), control forging shape and size, so the forging precision is low, processing margin is large, labor intensity is large, productivity is not high, so it is mainly used in single, small batch production.
