Whether heated by resistance or induction, our furnace specifications are driven by the customer. To provide the right solution, we utilize the customer’s extensive and specific process knowledge to determine the ideal performance criteria. The customer specifications of product size, mass, required temperature, uniformity, vacuum and / or positive pressure levels, and gas atmosphere conditions are the foundation of the final AVS furnace design.

AVS fabrication capabilities range in size from 4 inch (100mm) diameter mini furnaces, to hot zones in excess of 15 feet (5 meters). We have the ability to fabricate graphite, ceramic, or refractory metal hot zones in-house. The equipment we produce is for applications involving a combination of high temperatures, up to 2500°C, high vacuum down to 10-6 Torr, gas pressures up to 3000 psig (200 bar), and even hot pressing that ranges from 5 tons to more than 2400 tons of hydraulic force.
