Induction Hardening

Induction hardening forms the most critical part of manufacturing process. In this treatment, the metal part is heated by induction and then quenched. Then the hardness and brittleness of the metal is increased by martensitic transformation. We, at Rolex, handle various types of induction patterns and case depths with a thorough inspection, thus, ensuring that each component is in line with our customer’s specific requirement.
