What is forging

Forging is one of the treatment methods of metal pressure. Refers to the use of pressure to change the shape of the metal. The raw material obtains certain mechanical properties, and has a certain shape and forging size.

Forging function

Compared with casting, metal forging can improve its structure and mechanical properties. Hot deformation of cast structure after forging due to metal deformation and recrystallization, the original rough dendrites and columnar grains are refined, uniform particle size isometric recrystallization structure, the original steel is separated, loosened, pores, slag and other compaction and welding The organization has become tighter, improving the plasticity and mechanical properties of the metal.

The mechanical properties of castings are lower than those of the same material. In addition, the forging process ensures the continuity of the metal fiber structure, making the forged fiber structure and the shape of the forging consistent, the metal streamline integrity, to ensure that the parts have good mechanical properties and long service life, using precision die forging, cold extrusion, temperature extrusion resistance The pressing process is to produce forgings, and the casting cannot be matched.

Forgings are metallic objects that are subjected to pressure to form the desired shape or compression force of appropriate plastic deformation. This force is usually achieved by using a hammer or pressure. The forging process builds fine particle structures and improves the physical properties of metals. In actual use of components, the correct design can make the particles flow in the main pressure direction. Castings are made of metal by various casting methods to form objects, that is, liquid metal that is well smelted, with casting, injection, suction or other casting methods into the prepared mold, sand after cooling, processing after cleaning, etc., to obtain a certain shape, object Size and performance.
