What is Forging


Forging, is one of the metal pressure processing methods. Refers to the use of pressure to change the shape of metal raw materials to obtain a certain mechanical properties, a certain shape and size of the forging of a processing technology.

Forging features


Compared with the casting, the metal after forging processing can improve its organizational structure and mechanical properties. Casting tissue after forging process thermal deformation due to metal deformation and recrystallization, so that the original coarse dendrites and columnar grains into fine grain size, uniform size of the equiaxed recrystallization organization, so that the original steel ingot segregation, Loose, porosity, slag and other compaction and welding, the organization has become more closely, to improve the plasticity and mechanical properties of the metal.

The mechanical properties of the castings are lower than those of the same material. In addition, forging processing to ensure the continuity of metal fiber organization, so that the forging of the fibrous tissue and forging shape 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 process for the production of forgings, are cast can not match.


Forgings are objects where the metal is subjected to pressure, shaping the desired shape or the appropriate compressive force by plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process builds fine particle structures and improves the physical properties of the metal. In the practical use of components, a correct design can make the particles flow in the direction of the main pressure. Castings are made of various casting methods of metal forming objects, that is, smelting good liquid metal, with casting, injection, inhalation or other casting method into the prepared mold, after cooling down the sand, clean up and after Processing, etc., obtained with a certain shape, size and performance of the object.
