1. Improve the intrinsic quality of forged parts

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

2. Labour-saving forging process

The advantages of forging is a dense and relatively uniform organisation, performance is better than welding and casting, but the disadvantage is that it requires a larger deformation force, so the development of energy-saving forging process has been a research area of researchers are keen. At present, there are three main ways to save energy: ① reduce the constraint factor, commonly used in the actual production of diversion to reduce the deformation resistance; ② reduce the rheological stress method, the actual production of superplastic forming and liquid die forging belong to this method; ③ reduce the contact area.

3. Precision forging forming process

Forgings do not need to be machined to meet the tolerance requirements, has been able to control the accuracy of forgings within 0.01mm ~ 0.05mm. Net forming and near net final shape forging belong to this type of method. Less cutting-free machining is the machinery industry to improve material efficiency, improve labour productivity and reduce energy consumption of the most important measures and direction.

4. The use of composite technology

Forging billet is the use of jet deposition or semi-solid method of preparation, and then these billets and then through the forging process to prepare parts of the process. The actual production of blanks can be prepared with a variety of other forming process methods, and finally formed by forging, this process can be called composite process.

5. Forging process information technology

Forging process CAD, CAE, CAM and CAD/CAE/CAM-integrated, the realization of the whole process of forging virtual production, forging forging organisational performance prediction and defect prediction, artificial intelligence, neuron network and expert system to achieve the forging process of on-line quality inspection and on-line control, forging process, production process information management, enhance the efficiency of the production process, information integration into the forging process, the information technology is the most efficient, the information integration into the forging process. The information management of forging process and production process improves the efficiency of the production process, and the informationisation is the requirement of the times to melt into the whole process of forging.

6.Micro-forming technology

Usually refers to the deformation of parts less than 0.5 deformation, such deformation of the lattice size of the material used did not change much. At present, with the rapid development of microelectronics industry, the demand for microforming technology is also growing. However, one of the difficulties of microforming technology lies in its size effect.

7.Multi-point flexible forming

The application of group technology, rapid die change, etc., so that multi-species, small batch forging production can make use of high-efficiency and highly automated forging equipment or production line, so that its productivity and economy close to the level of mass production.

8 environmentally friendly forming technology

Environmentally friendly forming technology, including the forging process of green, harmless, reduce environmental hazards, while forging process to save energy, promote energy saving, environmentally friendly forming process.
