During the sintering stage of metal injection molding (MIM) temperatures of up to 2,550ºF are typical.  Binder removal and the frequent need to operate under partial pressure (hydrogen, argon, nitrogen) are essential to achieving required temperature uniformity and prevention of contamination to the work piece. This causes increased demands on several features of the furnace design.  The gas-introduction system, sealed MIM-boxes, and the distribution of the heating elements are all critical parts of the process. Both batch furnaces and pusher furnaces are used depending on production quantities and quality requirements.

Main Fields of Application:

• Sintering of MIM components in steels, Fe-Ni, Ti and other materials
