Hardening induction heating
DUOLIN Induction hardening is the most common form of heat treatment. It is widely used on shaft, gear, pipe and other part in automotive industry. Induction power is applied to the surface and causes the material to heat to a required depth then cool down rapidly by water, oil or other cooling medium.
Duolin as a induction hardening specialist, we can offer you fixed or scanning hardening, suitable transformer to meet different size case.
Advantages of induction hardening
l It treats a specific part of the piece (hardening profile)
l Frequency Control and heating times
l Cooling control
l Energy saving
l No physical contact
l Control and located heat
l Can be integrated in production lines
l Increase performance and saves space
l Induction hardening is faster than other forms of hardening.

Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of induction power supply (induction heater) and inductor (coil) that is a shaped to contour the part, and a work station where the part is held and presented to the coil.
