MICROWAVE HEATING DEVICE FOR PLASTIC BLANKS AND METHOD FOR HEATING PLASTIC BLANKS BY MEANS OF MICROWAVES

摘要

The invention relates to a method and a device for heating preforms (1) consisting of a thermoplastic material, said preforms being subjected to a deformation process following the heating thereof. The preforms are exposed to microwaves in a resonator (11) at least during part of the heating process.
