From Inductoheat - An Inductotherm Group Company

Presentation focuses on:
Novel approaches to induction heat treating of critical automotive components, including but not limiting to induction contour hardening of spiral, hypoid and bevel gears with diameters from 6" to 8" (patent pending) and sprockets. Patented CrankPro Technology for non-rotational hardening and tempering of crankshafts (V-4, V-6 and V-8) and camshafts with non-convention journals and lobes.
Specifics of induction hardening of hand tools (i.e., wrench jaws, hammers), fasteners, etc.
Induction heating of large-diameter (8 to 12 in. and larger) billets made from carbon steels, stainless steels and Inconel, including a comparative assessment of progressive multi-stage horizontal induction heating approach vs. static heating using vertical inductors (frequency selection, electrical efficiency, system flexibility, cost, etc.).
FluxManager® - technology for effective heating of carbon steel tubular goods (patented in 2007).
Developing compact and highly-efficient induction tempering and stress relieving systems.
