Development Trend of Forging Process

The development trend of forging process is:

① Improve the intrinsic quality of forgings, mainly to improve their mechanical properties (strength, plasticity, toughness, fatigue strength) and reliability. This requires a better application of the theory of plastic deformation of metals; the application of inherently better quality materials, such as vacuum-treated steel and vacuum-smelted steel; the correct pre-forging heating and forging heat treatment; and stricter and more extensive non-destructive testing of forgings (see NDT).

② Further development of precision forging and precision stamping technology. Less cutting is an important measure and direction for the machinery industry to improve material utilization, increase labor productivity and reduce energy consumption. The development of forging blanks with less oxidation-free heating, as well as high-hardness, wear-resistant, long-life mold materials and surface treatment methods will be conducive to the expansion of precision forging and precision stamping applications.

③ Development of forging equipment and forging production lines with higher productivity and automation. Under specialized production, labor productivity is greatly improved and forging costs are reduced.

The development of flexible forging forming system (application of group technology, rapid mold change, etc.), so that multi-species, small batch forging production can use highly automated forging equipment or production lines, so that its productivity and economy close to the level of mass production.

The development of new materials, such as powder metallurgy materials (especially double metal powder), liquid metal, fiber reinforced plastics and other composite materials forging processing methods, the development of superplastic forming, high energy rate forming, high pressure forming technology.
