Molybdenum Heat Shield or tungsten heat shield
As thermal insulation components, molybdenum heat shield and molybdenum covers play a important role for heat blocking and reflecting in sapphire growth furnace. A high purity, precisely sized, smoothly clean, easy assembly and appropriately designed heat shield is significant for crystal pulling quality.
The manufacturing techniques of molybdenum heat shield are powder metallurgy, sintering, swaging and finish processing. These years, with the development of LED, we have spent lots of time and funds for the development of molybdenum and tungsten products for the application of crystal growth furnace.
The molybdenum heat shield is riveted by molybdenum sheet and fixed by molybdenum wire and molybdenum rod.
