Free forging, we also call it open die forging. It is mainly refers to the processing method of using simple general tools or directly applying external force to the blank between the upper and lower anvils of the forging equipment to deform the blank, thereby obtaining the required shape and internal quality of the forging. The forgings produced by the free forging method call free forgings. The equipment used in free forging is mainly a ring rolling machine. Free forging is used to forge the forgings by hot forging. While die forging, also call it Closed Die forging, refers to the forging method of Forging Parts by using a die to shape the blank on a dedicated die forging equipment. Die forging can be divided into two categories according to its function: die forging die cavity and blank making die cavity.
