Application and introduction of powder metallurgy gear

The proportion of powder metallurgy parts gradually rise in automotive, motorcycle at present. But powder metallurgy manufacturer-ZCMIM think the most widely used is powder metallurgy gear.（http://www.zcmim.com/）

Gears belonging to structure parts in category of spare parts. This type is the most widely used of all parts. The use of powder metallurgy technology to produce gear can bear more torque, temperature and pressure. In terms of a full set gear designed and manufactured by specialized materials, it can be reduced about 30 percent by weight. 

PM gear accuracy depends on the expansion coefficient of its material as well as molds. Generally speaking, within 50 diameter  gear moulds made in China have higher level than that made in aboard. For helical gears, it can be further increased by one grade. One advantage of powder metallurgy gear is mass production and processing.
