The type and design of the induction coil determines how effectively and efficiently a workpiece is heated. Work coils range in complexity from a simple helical- or solenoid-wound coil (consisting of a number of turns of copper tube wound around a mandrel) to a coil that is precision-machined from solid copper and brazed.

Induction heating uniformity issues can cause a variety of problems with part quality. We often see these issues because of irregular heating patterns due to unusual part shape or nontraditional heating requirements.

Here are six ways you can augment your induction coil design or heating process to address common heating uniformity problems.

Coupling is the transfer of energy that occurs in the space between the heating portion of the coil and the workpiece. So, coupling distance is how big that space needs to be to balance efficiency and manufacturing requirements.

Induction coil design can have a major impact on part quality, process efficiency, and manufacturing costs. How do you know if your coil design is best for your part and process? Here are some induction coil basics and five tips to optimize your design.
