Induction hardening
Our hardening solutions are used by many of the world’s leading car manufacturers and their suppliers.
Introduction
Induction hardening uses induced heat and rapid cooling (quenching) to increase the hardness and durability of steel. It is a no-contact process that quickly produces intense, localised, and controllable heat. Induction is being used to harden numerous components, such as gears, crankshafts, camshafts, drive shafts, output shafts, torsion bars, rocker arms, CV joints, tulips, valves, rock drills, slewing rings, and inner and outer races.
- A fast and repeatable process that integrates easily into production lines
- Clean, safe, energy-efficient, and typically with a small footprint
- Individually treated workpieces; each piece is hardened to its precise specification
Induction hardening boosts throughput. It is an extremely fast and repeatable process that integrates easily into production lines.
