    AdvantagesPowder metallurgy (P/M) is an efficient and versatile method for manufacturing ferrous and non-ferrous machine parts and electrical and electronic components By mixing powders and compacting the mixture in a die, the resulting shapes are sintered, that is, heated in a controlled-atmosphere furnace to bond the particles metallurgically.

The diagram on the left shows the P/M process, which is cost effective in producing simple or complex parts at, or very close to, final dimensions in a variety of production rates ranging from a few hundred to several thousand parts per hour.

SMC Powder Metallurgy allows its customers to realize significant savings on a wide range of P/M products.
