Powder metallurgy is a manufacturing process in which metal powder is compressed into a solid part using high force. During compression the powder particles are mechanically adhered to one another. The compressed part is durable enough to be transferred to the next phase, sintering.
During sintering, the part is heated in a protective gas environment, and the part melts into a solid piece. After sintering the part is either ready to have finishing surface treatment, or some further machining.
The process minimizes material waste and production time compared to traditional methods. The method enables cost-effective production for even millions of parts per year.
Range of available materials is extensive. For example, it covers copper, aluminium, numerous grades of steel as well as stainless and acid proof steels. When necessary, metal powder mixtures can be customized to optimize strength and other desired needs.
