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.
