The inductor and inductor-machine have a very important rule of induction hardening. The most modern plants for induction heating allow to vary the power and the frequency along the profile to be treated that allow to obtain great results even in the more complex profiles but having a very well done inductor. As a consequence we design and do the inductors inside with highly qualified personnel and thanks to the collaboration with offices specialized in inductor design. This way in addition to a lowering of the prices and time of delivery, we can guarantee and certificate the all process.
