High-vacuum annealing and brazing imposes exacting demands on the purity and cleanliness of the furnace, on temperature uniformity and on the capability of achieving rapid-cooling.

Depending on the operating conditions and the products to be processed, metallic hot-zones and charge carriers made of molybdenum and tungsten are used.

• Vacuum brazing for applications in aerospace (brazing repair of turbine blades, brazing of honeycombs)
• Outgassing and clean annealing in electronics and medical technology
• Production of vacuum switches for power engineering
• Laboratory, production and special furnaces in development departments and in materials research

The PLANSEE Product Range
