Powder Metallurgy is a process that using metal powder as the raw material,by compacting and sintering to shape various metal parts.Generally,there are three basic processes on Powder Metallurgy,including powder mixing,compacting and sintering,while all the secondary process is done follow on the customer drawings,such as drilling,tapping and grinding,and surface treatment or heat treatment,etc. Powder Metallurgy process is very similar to ceramic producing process, so a series of Powder Metallurgy technology could be applied to the ready process of ceramic material.There are many superiorities on Powder Metallurgy technology,so it has become the key to the new material trouble.
Due to the existence of porosity in powder metallurgy parts,so usually the engineers have much doubts on the strenght of powder metallurgy parts,they thaught the strenght of powder metallurgy parts is worse than the steel.Actually,there is a series of standards on the strength of powder metallurgy components, so it could meet the various technical needs of different automotive parts.According to the American MPIF standard,based on the difference of powder ratio and the density, the strength of powder metallurgy material is about 170-1240Mpa,
With the development of Chinese automotive industry,more and more automotive metal parts would be produced by powder metallurgy technology.Nowdays,there is a higher requirement on energe saving needs of automotive industry, so conversely,it promotes the develoment of powder metallurgy technology.Sints company has more than 22 years experience of Powder Metallurgy and Metal Injection Molding technology,locating the leader position of powder metallurgy industry in China. Its new automotive parts factory "Jiangxi Tianqi Auto Parts Co.,Ltd" would be put into production at the end of June,2017,mainly serves to automotive VVT and Timing Chain engine system,exhaust system,etc.Thus it would improve our PM capacity grately and make us become more competective to win more large and famous customers all over the world.
