Admatec 450-CS-400 — Technical data

The 450-CS-400 is Admatec's high-temperature sintering furnace and, at 1,750 °C in air, reaches the highest temperature in the manufacturer's furnace range. It densifies ceramic parts that have already been debound, for example alumina or zirconia, to their final density. The chamber measures 400 × 400 × 400 mm and is heated by twelve Kanthal Super elements via three thyristor units, controlled by a Eurotherm EPC 3008 with ten programmes. Connected load is 26 kW on 400 V three-phase. Together with the 450-CD-400 debinding furnace it forms a line in which both steps run separately and at the same time.

Anyone buying a used 450-CS-400 should look first at the heating elements and their holders, since temperatures close to 1,750 °C put them under heavy strain. Replacement rods are expensive and their age has a clear effect on value. The insulation should be dimensionally stable and free of melt marks; residues suggest that parts went in without being fully debound. Checking the thermocouples and comparing set and actual curves in the controller shows whether the temperature is right.
