Free forging is a common metal forging process, which uses forging equipment to heat metal materials to a certain temperature in the absence of molds to achieve the processing of metal products of specific shapes and sizes. Compared with traditional forging, free forging does not require the use of molds or models, so it has higher flexibility and adaptability. The definition of free forging mainly includes the following aspects: no die forging: Free forging is a forging process carried out in the absence of a fixed die, which is different from traditional die forging or open die forging. Material heating: In the free forging process, metal materials are usually heated to a suitable temperature range to increase their plasticity and deformability. Free shape: Free forging can be made according to the needs of a variety of complex shapes, such as shaft parts, cams, connecting rods and so on. Accurate size: Free forgings can achieve the exact size required by controlling the degree of force and deformation during forging. In general, free forging is a metal forging process that is not limited by the mold, has high flexibility, and can achieve complex shape and size requirements. It has a wide range of applications in aerospace, automobile manufacturing, military and other fields.
