Precision die forging forming technology, i.e. near net shape forming technology, refers to the forming technology that can be used as mechanical components after parts are formed with only a small amount of processing or no processing, that is, to manufacture workpiece blanks close to the shape of parts. Compared with the traditional forming technology, it reduces the subsequent cutting volume, reduces the material, energy consumption and processing procedures, significantly improves the production efficiency and product quality, reduces the production cost and improves the market competitiveness of the products. Main application

1. Produce refined blanks and finish machining precision die forgings to obtain finished parts.

2. For the production of precision die forging parts, precision forging is the main part of forming parts, and cutting processing is omitted, while some parts of parts still need a small amount of cutting processing.

Precision forging technology has gone through 50 or 60 years of development. A large number of high-quality, high-efficiency, energy-saving and labor-saving precision forging technologies have emerged one after another. Precision forging technologies such as hot precision forging, warm precision forging, cold precision forging, cold temperature composite forming, compound forging and precision roll forging die forging composite forming have developed rapidly and are more and more used in the production of automobile transmission and engine gears abroad, It is widely used in automobile industry.

With the development of manufacturing industry, precision forging technology is more and more widely used, and the requirements for technology are higher and higher. The main development directions are as follows:

1. Computer simulation technology of forging process

2. Forging process is developing towards automation and flexibility

3. Green forging technology
