Process

The coil is the process.

Hardening, heating, brazing, annealing and forging are the same physics with a different coil, frequency and quench.

Gear hardening

Tooth-by-tooth or spin hardening with a coil that leaves the core tough.

Scan or static coils for axles, pins and journals with controlled case depth.

Continuous tunnels that deliver forging-temperature billets to the press.

Local joint heat for copper, carbide and steel — no open flame.

A travelling heat zone restores ductility on tube, pipe and wire.

Single-end, double-end and through-heating for forging and bending.

Sprocket and shifter hardening, curve heating, double-end heating, pipe heating, bar heating, quench and temper, shrink-fit and extraction.
