Induction heating for appliances and HVAC manufacturingÂ
Induction heating is widely used across household appliance and HVAC (heating, ventilation and air-conditioning) manufacturing, where its precision and repeatability suit high-volume brazing and bonding of components that must be leak-tight and consistent.
Applications in appliance manufacturing
- Brazing of heating elements in white goods such as dishwashers and washing machines
- Brazing and hardening of compressor parts in refrigerators and freezers
- Bonding of refrigerator and freezer bodies
- Brazing of faucet bodies — tube-to-socket, tube-to-tube and thread-insert brazing for faucet manufacturing
Applications in HVAC manufacturing
- Brazing of copper tube to aluminium heat exchanger joints, using an automatic filler-material feeder for consistent results
- Brazing of heat distributors, with multiple copper tubes brazed simultaneously
- Brazing of compressor parts shared with HVAC and refrigeration systems
- Tube welding
