Compared with the castings, metal after forging processing can improve its organizational structure and mechanical properties. Casting organization after forging method of thermal deformation due to metal deformation and recrystallization, make original bulky dendrite and columnar grain to grain is fine and uniform axial recrystallization organization, make the ingot in the original segregation, porosity, porosity, slag compaction and welded, such as its organization become more closely, plasticity and mechanical properties of the metal.

The mechanical properties of castings is lower than forging mechanical properties with the same material. In addition, the metal forging process can guarantee the continuity of fibrous tissue, the forging of fibrous tissue and forging appearance consistent, metal flow is complete, can guarantee the parts with good mechanical properties and long service life with precision die forging, cold extrusion, extrusion temperature and other process of forging, is incomparable by casting

Forging is a metal pressure, through the shape of the plastic deformation shape requirements or suitable compression force. This kind of typical power by using a hammer or pressure. Forging process built fine granular structure, and improve the physical properties of metal. In parts of practical use, a proper design can make the grain flow in the direction of main stress. Casting is to use all kinds of casting method for metal forming objects, namely the good liquid metal smelting, casting, injection, inhaled or other casting method into the prepared mold, after cooling the shakeout, cleaning and post-processing, etc., of a certain shape, size and properties of objects.

There are many different kinds of forging processes available, however they can be grouped into three main classes:

Drawn out: length increases, cross-section decreases

Upset: length decreases, cross-section increases

Squeezed in closed compression dies: produces multidirectional flow

Common forging processes include: roll forging, swaging, cogging, open-die forging, impression-die forging, press forging, automatic hot forging and upsetting
