Custom Induction Coil Designs

Problems with your induction applications could be due to the Induction Coils.

Induction coils are the energy transmitter for the induction power supply – radio frequency (RF) generated in the coil creates a magnetic field that then gets induced into the workpiece, heating it up.

An issue with the coil could compromise your application and your entire manufacturing process. Do any of these problems sound familiar?

  • Underheated parts
  • Overheated parts
  • Inconsistent heating
  • Shorting
  • Damage to parts
  • Coil overheating
  • Induction heating power supply tuning issues

Scroll down to take a deeper dive into some of these problems.

Conical Induction Coil


Are your parts overheating or worse, melting?  While induction is great because you can control the process, sometimes getting the process down exactly can be tricky, particularly if you’re using your induction heater and induction coil for multiple applications.  Induction coils are not one-size-fits-all: An induction coil with five turns, for instance, might be great at heating large-diameter parts but the resulting RF field could turn a smaller diameter piece into a dripping mess.

You don’t necessarily need to buy a different induction heater for every application, though – as long as your induction heater is properly sized and tuned, you may just have to switch coils.

If you’ve been using the same coil and induction heater for your application for a while, but have suddenly started having overheating issues, you need to look at a couple of other factors:

  • Has the distance of the workpiece from the coil changed? Possibly the fixture holding the workpiece in place has shifted or has been damaged.
  • Does the induction heater need re-tuning? Are there power fluctuations on the panel, or any kind of machine faults noted?
