Induction Heating Coil Design

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?

We can build and design Induction Heating Coils to your specifications or our Applications Engineers can work with you to determine the best coil design for your specific requirement.

Below are just a few of our basic coil designs that can be ordered to your size and fittings.
