Vacuum Furnace for Heat Treating Industry Applications

Vacuum Furnace

AVS Vacuum Furnace is manufactured to satisfy our customer’s temperature and vacuum atmosphere requirements. AVS vacuum furnace allow various combinations of high temperatures up to 3000°C, high vacuum to 10-6torr, partial pressure gas atmospheres in the millitorr or torr ranges, and positive pressures up to 1 atmosphere (14.7 psig). AVS has in-house capabilities to fabricate graphite hot zones using soft felt or rigid g-board insulation, as well as non-particulate metal hot zones including stainless steel, nichrome, inconel, molybdenum or tungsten, when required.

AVS adherence to ASME codes allows AVS the confidence to offer the only standard 5 year chamber warranty in the industry. Vacuum furnace chambers are manufactured by certified AVS welders in our facility and, depending on requirements, can be fabricated from mild steel, 304 stainless steel or 316 stainless steel. The standard leak rate on an AVS vacuum chamber is 5µ/hour, but through the use of electro-polishing or with specialty coatings, can be fabricated to meet tighter specifications if required.
With the addition of a condenser system or hydrogen burn-off system, an AVS Vacuum Furnace can also allow for combination debinding and sintering. Debinding can be performed in positive pressures or partial pressures of flowing argon, nitrogen, hydrogen, or other inert or reactive gases or gas mixtures.
