Powder metallurgy, a type of manufacturing processing of metal parts with few or no cutting, has been more widely used inautomotive industry. There are more than 130 kinds of metal parts likely produced by powder metallurgy in a car. In other countries, powder metallurgy manufacturers mainly supply for automotive industry. However，there’s a low use of powder metallurgy parts in domestic automotive industry.
Powder metallurgy is a manufacturing processing technology that uses metal powder as the feedstock, which is subjected to shaping and sintering, to make metal material and products. Normally, powder metallurgy consists of basic 3 steps, mixing, shaping, and sintering. Due to the competitive advantages, powder metallurgy has become to the key to resolving new material, and will play a great role in the development of new materials.
Many engineers have misgiving about the strength of the powder metallurgy parts for the porosity of powder metallurgy parts. They think it is much weaker than machined parts’. Actually, the strength of the powder metallurgy parts has its own standard, and will meet kinds of the technical requirements of auto parts.
With the development of Chinese automotive industry, more and more metal parts could be made by powder metallurgy, which have caused a high use in automotive industry. On the other side, high demand for energy conservation and emission reduction in automotive industry promotes the development of powder metallurgy. Finally, Sints hopes that powder metallurgy can make a greater contribution to energy conservation and emission reduction in automotive industry.
