As is known to all, powder metallurgy mechanical structure has advantages of less or no cutting and energy and material saving;
powder metal has the advantages of high production efficiency, suitable for mass production; with diversity of characteristics, which can meet the performance requirements of the various parts of the structure. So it has been widely used in the automotive field. According to the relevant information, the use of powder metallurgy parts of the car has more than 1000 kinds of. More than half of the total amount of powder metallurgy structural parts in the world is used in automobile industry. The mass production of powder metallurgy parts will lead to the rapid growth of the demand of the powder, so as to realize the common development of powder metallurgy parts enterprises and raw materials enterprises.
The vigorous development of the automobile manufacturing industry, make people have a certain understanding of the technology and economic characteristics of powder metallurgy parts. Especially in the recent introduction of models, and the emergence of many new parts, therefore in the production in addition to further expand the general manufacturing technology, but also need to with some special technology to manufacture, such as: metal injection molding, temperature and pressure forming, powder forging, hot isostatic pressing, cold and static pressure and so on, so that the powder metalparts and application in the field of automobile industry will be more and more widely.
