In many cases, powder metallurgy gears have low requirements for mechanical properties and high dimensional accuracy. Generally, the density is 6.9~7.1. The forming process is not high. The sintering process is high. To prevent sintering deformation, Cu can be added. Anti-sintering shrinkage. With the development of technology, the demand for high-performance powder metallurgy iron-based parts is getting higher and higher, which must increase the density of the powder compact, which puts forward higher requirements on the forming process, and develops technologies such as warm pressing and high-speed pressing. , The density of parts can reach 7.2~7.4. In order to further improve the mechanical properties of powder metallurgy parts, it is also necessary to increase the density of the compacts. This must be considered from the powder preparation. Pulverizing technology and powder pretreatment technology have become the focus. Now high-quality water atomized iron powder is used to plasticize the powder. Processing, the green compact density can reach more than 7.5, which is the highest level of powder metallurgy iron-based parts today, which was unimaginable ten years ago. custom metal parts
