A device for the induction heating of a billet of metal of high electrical conductivity has: a tubular body supporting a plurality of permanent magnets arranged inside the tubular body, angularly spaced apart from each other and arranged so as to be alternated with opposite polarities. The device also has a support for the billet that is arranged inside the tubular body and faces the magnets. The device also has a motor adapted to rotate the tubular body with respect to the billet in order to induce currents in the billet that circulate within the metal material, obtaining the heating of the billet by the Joule effect. An integral cooling system for the permanent magnets is provided, this being carried by the tubular body and suitable for feeding cooling air flows between adjacent permanent magnets.

Device for induction heating of a billet

Preform heating device able to perform a precise and strongly localised heating of the preforms before the blow moulding phase of the plastic bottle or container production process. This device has an innovative construction configuration, thus allowing high efficiency thanks to the significant reduction in the energy required to reach the project temperatures in the heating element in a very rapid way. The inductor does not heat the preform directly, but takes to the temperature set, through the concentration of the magnetic flow, generated by the passage of current, a conductor material of a particular form that, by irradiation and convection, in turn heats the PET.
