Induction Atmospheres has developed an efficient new induction heating vacuum furnace designed for industrial brazing and general-purpose metal heating. The Model VF-20 efficiently heats parts of virtually any shape in a high-temperature, high-vacuum environment.

The VF-20 is ideal for brazing parts of unusual shapes and repairing “orphan” parts from other heating processes. To facilitate continuous flow manufacturing, the VF-20 utilizes the latest advances in quick, clean solid state induction heating technology. The furnace requires less than eight minutes to reach 1900°F; cool down time to 400°F is less than 20 minutes. The furnace operates at high vacuum or partial pressure of an inert gas. The chamber has base vacuum of 5x10-6 Torr with a leak-up rate of less than 1 micron per hour.

“The VF-20 facilitates lean manufacturing by moving the vacuum heating process away from a centralized area, into the manufacturing cell”, said IA President Steve Skewes. “Our customers report improved manufacturing workflow with dramatic improvements in overall cycle time”.

Founded in 2002, Induction Atmospheres is an independently-owned system integrator with extensive laboratory facilities, engineering expertise, full in-house machining and manufacturing capabilities. Clients such as General Electric, NASA, General Motors, Boston Scientific, Lufthansa Technik and Siemens have purchased IA turnkey heating systems for industrial brazing, welding, hardening and general-purpose induction heating applications.
