In recent years, with the rapid development of China's economy, all walks of life have also improved their own development speed. At the same time, the technology of all industries has also been rapidly developed and improved. Powder metallurgy technology is no exception, because its application scope is more and more extensive. In all industries of the national economy, it is basically applied to mold processing and production. It is not only closely related to the entire machinery industry, but also closely related to people's life. Even some industries can not be separated from powder metallurgy technology, which makes mold technology imminent.

In our daily life, we often see that 60% - 90% of the parts of some products are manufactured by molds. If the precision is low during mold processing, the product quality is poor, and the mold life is low, the product processing cost is high. Modern mold has become a capital intensive and technology intensive industry, and it has become a mutually dependent relationship with high-tech. On the one hand, mold has become an indispensable equipment for high-tech industrialization, on the other hand, mold itself has adopted a large number of high-tech, so mold manufacturing has become an important part of high-tech industry. At the same time, the rapid, high quality, low consumption, environmental protection and other advantages of the forming parts of the die also reflect the national scientific development concept and sustainable development strategy.

Nowadays, the rapid development of powder metallurgy products has also brought rapid development to mold manufacturing. There are single integrated mold to complex combined mold, and the number of products is rising. This puts forward new requirements for the current mold making, so the selected materials must meet the requirements of high life, high strength, high wear resistance, high toughness, high heat resistance, etc. This puts forward higher requirements for mold makers. This requires not only knowing the mold manufacturing process, but also being familiar with the properties and characteristics of materials.

The mold processing equipment adopts computer technology and precision machining center, which has basically kept pace with the world's advanced level. The mould made by powder metallurgy technology has been applied to many automobile structural parts in batches, which represents the development trend of the mould.
