Induction Tooling Inc. has disrupted the traditional approach to validating selective hardening inductors, getting them into production faster than ever before and with improved production results. Mirroring the heat-treat production parameters, the inductor, commonly called a coil, can be characterized to produce a hardening pattern that meets the case depth and metallurgical requirements. The number of variables influencing the induction-hardening pattern produced by a specific power supply, inductor and part geometry are extensive. This characterization process often involves small changes to the inductor geometry, gapping between the inductor and workpiece, and the use of flux intensifiers or targeted quenches.
