Forging is the pressure exerted by metal through the shape required for plastic deformation or appropriate compression force. This force is usually achieved by using a hammer or pressure. The forging process establishes a fine particle structure and improves the physical properties of the metal. In the actual use of parts, correct design can make particles flow to the direction of main pressure.
Forging production solves the control of heavy forging forming and its internal organization and performance. In order to obtain the required shape, size and quality requirements, the basic purpose of forging is to use impact load or static load (forging hammer processing or hydraulic processing) to obtain the required shape and size through forging equipment or die, so that the mechanical properties and internal organization of heavy forgings can meet certain technical requirements. Therefore, heavy forgings must be forged.
