Precision forging is a process that can produce forgings with high surface quality and dimensional accuracy.

Due to the high strength and good toughness of the parts manufactured by the forging process, they are suitable for mass production, so nearly 60% of the parts on the automobile are forged. In recent years, with the rapid growth of automobile production, the integration of parts is also in the process of synchronous planning when the OEMs are upgrading and integrating the vehicle capacity. In order to reduce the size of CVT gearbox and meet the requirements of lightweight, JATCO of Japan combined the gear and shaft into a pulley and achieved near net forming. After the modification, the structure is more compact and the environment is more friendly. More and more vehicle enterprises are pursuing lightweight and fuel saving. Replacing cutting process with precision forging technology has become the main direction of new product development. All these provide opportunities for the development of precision forging.

From the current practice, precision forging can reduce the manufacturing cost of the entire supply chain, and the general saving rate is more than 15%. Although the forging cost increases after the precision forging process is adopted, the machining cost is reduced, thus greatly reducing the total cost. For example, the manufacturing process of replacing synchronous gear and body separately with gear integral forging can save about 25% of production cost, which represents the trend of gear processing of automobile transmission in the future.

Another important feature of precision forging is that the manufacturing cost gradually decreases with the increase of production, which mainly reflects the advantages of die forming technology, high efficiency and high consistency. Although the fixed cost is high in production, the production efficiency is also high. For parts produced in large quantities, only a small amount of investment is required to improve the capacity, which can greatly improve the capacity.

Traditional automobile forging enterprises need to invest in precision forging research and investment in order to improve the competitive advantage of automobile parts, so it is imperative to develop precision forging.
