Powder metallurgy is the forming of metallic powders into parts by means of high pressure and subsequent heat treatment, called sintering.
Sophisticated moulding technology allows long as well as short runs and in addition individual production of precision parts.
Sintering is the key technological process in powder metallurgy. Sintering transforms porous green compacts of powder into metallic components suitable for further processing, by means of a combination of diffusion and surface tension under high temperatures.
The so-called solid state sintering takes place below the melting point of the metals and therefore guarantees the manufacture of compact, almost completely dense parts, avoiding melting. With another process, the so-called liquid phase sintering, a relatively small amount of binder material becomes molten and covers the particles of the base metal.
