Induction hardening
Our hardening solutions are used by many of the world’s leading car manufacturers and their suppliers.
What is induction hardening?
What are the benefits?
- 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
Where is it used?
Induction is used to harden numerous components. Here are just a few of them: gears, crankshafts, camshafts, drive shafts, output shafts, torsion bars, rocker arms, CV joints, tulips, valves, rock drills, and slewing rings, as well as inner and outer races.
ENRX hardening solutions are utilized across a wide range of industries globally. However, most systems fall into the following categories.
