We have designed shieldings made of an optimized quantity of W, ML, and Mo sheet layers to keep the heat loss of your furnace as low as possible during the process. A crucial factor here is the thermal radiation exchange between the sheet layers as well as the extremely low emissivity of molybdenum. Furthermore, our shieldings made of molybdenum, tungsten, and their alloys have a low specific heat capacity, enabling fast heating and cooling rates at short evacuation times, high process purity (graphite-free shielding), and short process cycle times. This makes them extremely well suited for use in the high-vacuum and ultra-high vacuum range. Using new, tailor-made designs, we can optimize the shieldings for your application in terms of weight and energy costs.
