Combi-furnaces up to 1400 °C

Combi-furnaces for debinding and sintering
- with air preheating and safety equipment -
T max. 1280 °C - 1400 °C

Combi-furnaces allow debinding and sintering processes to be performed without a change of furnace. For the debinding process in the lower temperature, preheated fresh air is blown in gently through a large number of optimally positioned ceramic tubes with air outlets. The result is excellent temperature uniformity and a high change of atmosphere. This ensures safe and reliable removal of organic components from the furnace.
When debinding has finished, the sintering process is initiated by a programmed controller without transition and without intermediate cooling. The system is then operated as a sintering furnace with the advantages of high-temperature capability, a steady sintering atmosphere and long service life.

Safety equipment
Combi-furnaces can be fitted with safety equipment for monitoring the pressure inside the furnace, the volumetric flow of fresh air and exhaust air, with emergency functions for preventing the formation of explosive mixtures.
