Hot die forging process: the key technology of precision forging

Hot die forging is a commonly used precision forging technology. It is a precision forging method in which the metal blank is heated to a temperature higher than the recrystallization temperature of the material, and the metal blank is plastic formed into the shape and size of the forging by means of a mold.

In the hot die forging process, the metal blank is first heated to the appropriate temperature and then placed into the mold for forming. Because the metal blank has good plasticity at high temperatures, it can be molded more easily to form the desired shape and size. At the same time, the use of the mold also makes the forming precision higher, can meet the requirements of precision forging.

Hot die forging has some advantages. First, it can significantly improve the utilization rate of metal blanks and reduce the waste of materials. Secondly, due to the use of molds, the accuracy and efficiency of forming can be greatly improved, and the forming technology that can meet the requirements of parts can be reduced by subsequent processing or no longer processing. In addition, the hot die forging process can also produce more complex forging shapes and sizes to meet a wider range of applications.

In addition to the ordinary hot die forging process, there are special processes such as isothermal forging, superplastic forging, and powder hot forging, which can play a better role in some specific application scenarios. For example, isothermal forging can produce forgings with more uniform mechanical properties, superplastic forging can use the characteristics of superplastic materials to produce more fine forgings, and powder hot forging can be used to produce high-precision, high-density, high-performance metal parts.

In short, hot die forging process is a very important precision forging technology, in automotive, aerospace, electronics and many other fields have a wide range of applications, it can not only improve the utilization rate of metal blanks and forming accuracy, but also can produce more complex, high-performance forgings, for the development of modern manufacturing industry has made an important contribution.
