HEATING CHAMBER

Induction hardening is commonly used in the automotive industry, as it can quickly and selectively harden the surface of metal parts. In this method, a copper coil is placed near the surface of a metal component, which allows heat to transfer to the metal. Once it is quenched, the material is significantly harder than it was previously.
