Powder Metallurgy--A green manufacturing technology

In the last few years, the immoderate use of high-carbon fuels leads to more extreme climates, which badly damages our lives. Thus, in order to achieve the harmony between people and nature, we have to change our lifestyles, save energy to reduce the emissions of carbon dioxide and protect our nature to welcome the Low-carbon Age. Therefore, while new energy automobiles appear gradually, powder metallurgy parts, an important part of the new energy automobiles, is promoted to reach the demand for energy conservation and emission reduction.

Material sustainability: the major advantage of powder metallurgy is final shaping capacity. For example, while making toothed parts, the usage rate will be less than 60% for conventional drilling processing, however, it will be 95% for powder metallurgy.

Energy sustainability: as far as we know, the final shaping will be finished after several heating and re-heating processes in conventional manufacturing processes.

About powder metallurgy, all steps are finished under temperature below melted point, except for a melting process in powder production process, which not only save energy, but also better material properties. Normally, the energy consumption of powder metallurgy is around 44% of conventional processing’s.

Environment sustainability: In general, we can pack and deliver the products after sintering, the final shaping capacity in powder metallurgy. Mostly, the cutting fluid and other poisonous pollution created in powder metallurgy process are few. Therefore, Powder metallurgy industry does no harm to the environment at all, comparing with others.
