Chamber Furnaces - Vacuum furnaces
High Temperature Chamber Furnaces - Metallic furnaces
Metallic furnaces
made of Molybdenum and Tungsten
The metallic furnaces have no fibre insulation, permitting the greatest possible purity of the process atmospheres or the best possible final vacuum. The complicated designs are employed for specimens requiring treatment in carbon-free atmospheres.
It finds application in the lighting industry, metal powder injection moulding, tempering of saphirs, heat treatment of metals, sintering of pellets in the nuclear industry, manufacture of radar tubes, metallisation of ceramic components, high vacuum brazing etc..
