Induction Heating

Lever Induction Heating

At MSI, both high frequency and low frequency induction machines are available.

Induction hardening is a process used to selectively harden areas of a metal part without affecting the properties of the part as a whole. The area to be hardened is placed within an alternating current magnetic field created by an induction coil.  It is heated to above its critical transformation temperature for a specific amount of time and then quenched in water or oil. As electronic controls are applied to all aspects of the heat cycle, accurate, repeatable, heating patterns and resulting hardness values are obtainable.

Higher frequency induction processing creates a shallower heat zone, and lower frequency units can create heat zones to a much greater depth if desired.
