During the sintering stage of metal injection moulding (MIM) temperatures of up to 1400°C are typical. Binder removal and frequent need to operate under partial pressure (hydrogen, argon, nitrogen) places demands on several features of the furnace design, in order to achieve the required temperature uniformity and to prevent contamination of the work-piece.

To this belong the gas-introduction system, the use of sealed MIM-boxes and the distribution of the heating elements. Both batch furnaces and pusher furnaces are used according to production quantities and quality requirements.

Main Fields of Application:

• Sintering of MIM components in steels, Fe-Ni, Ti and other materials
• Production of components for the watch industry, medical technology, implants, weapons manufacturing, textile industry, electronic devices, automotive industry etc.
