Abstract
The invention relates to a method and a device which are used to heat materials in order to produce objects industrially, especially by mass production, and which allow a large variety of transformation methods.
Claims20
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.

Device for heating materials in order to produce objects industrially, permitting a great variety of transformation methods, said device comprising:
- generators of electric currents of a predetermined intensity and of a predetermined frequency, supplying inductors and generating electromagnetic fields,
- a mold comprising two elements located opposite each other, both being made of an electrically conductive material, at least one element comprising a face forming a heating zone for heating a material placed between the two elements, said inductors surrounding said two elements,
- means for applying the electromagnetic fields to at least part of at least one of two elements and
- an insulating electric interruption or gap, being arranged between said elements such that the electric currents induced by the electromagnetic fields circulate in a closed circuit in each said element, and on said surface of said heating zone.
