Coil services

From initial concept to a buildable induction coil

The most useful coil design combines electromagnetic performance with mechanical access, coolant flow, insulation, repeatability and maintainability.

New coil concepts

Develop a coil approach around the part, target heating zone, available frequency, process time and loading method.

Existing coil optimization

Review slow heating, uneven temperature, poor coupling, short coil life, arcing, difficult loading or inconsistent results.

Manufacturing coordination

Translate the application into drawings, interfaces and build requirements that can be sourced through an appropriate manufacturing partner.

Design inputs

Coil geometry must support the required heat pattern

A coil is not simply bent copper tubing. Turn spacing, workpiece clearance, current direction, magnetic flux concentration and the relationship between coil and part influence where energy is deposited.

  • Encircling and helical coils for cylindrical parts
  • Pancake coils for one-sided or face heating
  • Internal coils for bores and inside diameters
  • Hairpin, channel and shaped coils for localized zones
  • Split or clamshell concepts where loading access is limited

Engineering tradeoffs

Performance, durability and operator access belong in the same design

The highest electromagnetic efficiency is not useful if the part cannot be loaded consistently or the coil cannot survive the production environment. We consider practical constraints early so the proposed design can be built, cooled, insulated and maintained.

Electrical

Power, frequency, current path, matching range, coupling and flux concentration.

Mechanical

Part loading, fixtures, clearances, thermal expansion and repeatable position.

Thermal

Coolant flow, hot spots, insulation, reflected heat and duty cycle.

Production

Cycle time, changeover, serviceability, expected life and spare strategy.

Information that helps us evaluate your requirement

You do not need a finished specification. The items below help us understand the real constraints and ask better questions.

Part information

  • Drawing or dimensional sketch
  • Material and condition
  • Photographs and accessible surfaces
  • Area that must be heated

Process target

  • Application and target temperature
  • Desired heat pattern or depth
  • Heating and total cycle time
  • Production quantity or duty cycle

Existing equipment

  • Power-supply make and model
  • Power and frequency range
  • Workhead or transformer details
  • Cooling and connection information

Replacement coil? Include photographs, critical dimensions, connection details, failure location and any available drawing. If the original coil produced an acceptable heat pattern, say what worked as well as what failed.

Have a part that needs a better coil?

Send the drawing, material, heating objective and equipment information. We will review the requirement and identify the most useful next step.
