  • How to Get the Most Out of Your Induction Coils
    Induction coils are crucial components. They are, after all, what actually delivers heat to the workpiece during the heating process. But all too often basic coil maintenance is neglected. The results? Sub-standard performance, off-grade products, unnecessarily high costs and acute production
  • Induction Instruction
    'Induction Instruction' is a new series of short articles where EFD Induction experts write about various aspects of induction heating. For this first article, Leif Markegård, senior R&D engineer at EFD Induction Norway, describes what's important when designing induction coils.
  • Industrial Induction Heating: All You Need to Know
    Induction heating is a safe, non-contact, and meticulous process for heating electrically-conductive materials like steel, graphite, copper, brass, silver, gold, aluminium, and carbide. It involves a complex amalgamation of electromagnetic energy and heat transfer through an induction coil, melting
  • RFID Coil Design
    . Alternatively, a small loop antenna coil that is resonating at the frequency of the interest (i.e., 125 kHz) is used. This type of antenna utilizes near field magnetic induction coupling between transmitting and receiving antenna coils.
  • Tempering an audio speaker screen [PFS]
    The speaker screen was placed over the induction coil and the power was turned on. The screen heated to the desired temperature within just one second...
  • Tempering an audio speaker screen [IH]
    The speaker screen was placed over the induction coil and the power was turned on. The screen heated to the desired temperature within just one second...
  • Melting the end of a plastic tube to create a seal
    Induction is used with a single turn coil encapsulated in custom blocks sealing the tube. Two tubes are placed between the coil blocks and a 7lb (3.2kg) load is applied to the top of the coil.
  • Bonding an Arthroscopic Device (.pdf)
    Induction heating provides localized, even heating of sheath, reduced discoloration, innovative coil design which eliminates fixture heating...
  • Brazing brass tube and fitting assemblies [OH]
    This smaller assembly was fluxed and placed into the induction. heating coil. A braze pre-form was placed onto the tube and. the induction power was turned on. After 28 seconds the braze. pre-form had flowed and made a perfect fillet. The parts were. then rinsed with warm water to remove the flux
  • Preheating steel rods for forging in a fastener manufacturing process
    Induction is effective heating steel rods to 2100 ºF (1149 ºC) evenly across their length in 25 seconds. This innovative solution employs eight coils to heat eight rods to the desired temperature in a parallel process...
  • Brazing a brass tube assembly [valve manufacturing] [MEC]
    With the recommended coil configuration, the cycle time turned out to be 25% less than what the client was targeting, resulting in increased production efficienc; a good braze joint was formed, and induction's consistency and repeatability proved valuable...
