Title: DEVICE FOR CONVERTING MATERIALS USING INDUCTION HEATING AND DEFORMABLE COMPACTING MEANS
Abstract:
The invention relates to a heater (10) for converting a material (44), comprising a lower mould body (12), or die, made of an electrically conducting material and having a moulding zone (14) intended to be brought into contact with the material to be converted; an upper body (20) having no moulding zone, made of an electrically conductive material; inductor means (30) for generating a magnetic field surrounding the die (12) and the upper body (20); the die (12) and the body (20) being electrically insulated from each other during the induction heating phase, so that the opposing faces of these two bodies define a gap (40) in which the magnetic field circulates, said field inducing currents in the surface of the moulding zone (14) of the die (12), thus making it possible to localize the action of the inductors at the moulding zone/material to be converted interface; and deformable compression means (42, 46) placed between the die (12) and the upper body (20), which are capable of exerting uniform pressure on the material to be converted.
