摘要

mold, a mold making process and a plastic or composite product manufacturing process by means of that mold. The present invention relates to an induction heated mold comprising at least one bottom and one top, delimiting a cavity into which a molding material to be washed at a temperature ttr greater than 20 ° C is introduced, then formed at least one of the parts of the mold having a heat transfer zone with the material to be modulated, the heat transfer zone comprising at least one sub-area consisting of at least one ferromagnetic material, whose curing point is between 20 and 800 ° C and is in contact with the material to be molded and / or a non-ferromagnetic coating with a thermal conductivity exceeding 30 wm -1k-1. It also relates to mold making processes according to the invention and to a process for manufacturing a plastic or composite product with the aid of molds according to the invention.
