Abstract:
1. Method for heating materials in order to produce objects industrially, permitting a great variety of transformation methods, said method comprising: generating electromagnetic fields by means of inductors through which electric currents of a predetermined intensity and of a predetermined frequency flow, applying said electromagnetic fields to two elements forming a mold located opposite each other, both being made of an electrically conductive material, at least one said element having a face forming a heating zone, said inductor means surrounding said two elements, said materials to be heated being placed between said two elements to be heated by said heating zone, arranging an insulating electric interruption or gap between said elements such that the electric currents induced by the electromagnetic fields circulate in a closed circuit in each said element, separating the two elements after heating the materials removing the materials.
