Induction Heating in Appliances & HVAC Industries


Appliances and HVAC manufacturers heavily rely on flame brazing for their brazing operations, but in recent years the industry is shifting towards induction brazing. The induction brazing equipment can provide controllable heat and ensure very good quality and repeatability of the brazed joints which makes it the preferred choice for their brazing processes.

Induction brazing is an ideal solution for high-volume, repetitive joining applications. Our equipment provides immediate, stable, consistent heating with precise control, with no open flame present which results in increased safety and reduced environmental impact. Ultraflex has a long track record of providing induction brazing solutions to major manufacturers within these industries. Our team has experience developing customized systems for integration into existing assembly lines and the capability of designing new, turnkey systems.

We offer manual, semi-automatic, or fully automated robotic systems depending on the specific requirements of the process. High-volume production lines for AC units, Appliances, or Heat pumps benefit significantly by implementing Ultraflex industrial brazing cobots.

How Induction Heating is used in Appliances and the HVAC industry?

  • Induction brazing of heat exchanger coils and radiators
  • Copper, steel, or aluminum pipes and tubes brazing and soldering
  • Automated brazing of heat pump components and assemblies
  • Brazing of compressor or refrigerator parts: condensers, evaporators, expansion valves
  • Soldering of wires, sensors, and electrical components in appliances
  • Induction bonding of metal to plastic parts or adhesive curing
