For nearly 30 years, powder metallurgy technology is developing rapidly, so far, powder metallurgy technology is the manufacturing technology of high strength, high density, complex shape, and no cutting, and processing method of production of new materials.
It is mainly used for ferrous parts, and its main material is carbon steel and low alloy steel, and it also used for high temperature alloy. Using injection molding,the density amounted to 96% of theoretical density. As part of the transmission mechanism of the wing screw lines with nickel ring as an example, in the past with forging stock subject to 14 procedure and adopt injection molding, can make almost WuYuLiang parts, only a small amount of grinding and calibration, and the parts with high corrosion resistance and good mechanical properties.
