As we all know, the production of mechanical structural parts by powder metallurgy has the advantages of less and no cutting, so it saves energy and materials; It has the advantages of high production efficiency and is suitable for mass production; With the characteristics of material diversity, it can meet the performance requirements of structural parts for different purposes. Therefore, it has been widely used in the automotive field. According to relevant information, more than 1000 kinds of powder metallurgy parts have been used in automobiles. More than half of the global total amount of powder metallurgy structural parts is used in the automotive industry. The mass production of automobile powder metallurgy parts will drive the rapid growth of powder demand, so as to realize the common development of powder metallurgy parts enterprises and raw material enterprises.

With the vigorous development of automobile manufacturing industry, people have a certain understanding of the technical and economic characteristics of powder metallurgy parts. In particular, many new parts appear in the recently introduced models. Therefore, in addition to further expanding the general manufacturing process, some special processes need to be used in production, such as metal injection molding, warm pressing, powder forging, hot isostatic pressing, cold isostatic pressing, etc., so that powder metallurgy parts will be more applied in the field of automobile industry Wider.
