Whether you need surface hardening for automotive parts, mining tools, or industrial shafts, our state-of-the-art induction equipment ensures optimal results with minimal distortion.
Induction hardening is a heat treatment process that uses electromagnetic induction to rapidly heat the surface of a steel part, followed by immediate quenching. This creates a hard, wear-resistant outer layer while maintaining a tough, ductile core.
It is ideal for parts subject to high stress, friction, or impact, such as:
