Forging is a core metal plastic forming process in the mechanical manufacturing industry, widely applied in high-end manufacturing fields such as heavy industry, automobile parts, wind power equipment and mining machinery. Different from the integral pouring forming of casting, forging relies on the plastic deformation characteristics of metals. Through external hammering, extrusion and pressing, the metal blank produces directional deformation and the internal metal structure is remodeled. This process manufactures mechanical parts with high strength, high toughness and high stability, and serves as a key production process for heavy-duty and precision stress-bearing components.
