Our Chinese powder metallurgy products industries was started from 1950's ,as the continuous development of automobiles industry and as the advantage of material saving about powder metallurgy,so it is becoming more and more be taken seriously.Nowadays the production of our domestic powder metallurgy parts has reached a high-speed development period.In recent years, some new technologies are keep springing up,such as mechanical alloying,metal injection molding,warm compacting,spray forming,microwave sintering,electric discharge,etc,so powder metallurgy material and technology are becoming more and more be taken seriously all over the country,thus it is used to produce parts more and more wide.
Nowadays powder metallurgy technology is toward a high density,high property,high integration and low cost directions to get more progress. In recent years,a series of new powder metallurgy technologies are appearing and presenting an accelerated development situation.
Much spare parts would be needed on the production process of automobiles,and it is no doubt that there would be a very strict requirement for the auto parts,while sometimes the requirement would be contradictory.But powder metallurgy technology could meet these requirement. One side,we could produce the parts with high precision,high smooth finish,excellent mechanical properties and high reliability;the other side,the massive production and low production cost could be realized if use powder metallurgy to finish the parts.
