Abstract
An induction-heated mold, including at least one lower portion and one upper portion defining a cavity inside of which a molding material is to be brought to a temperature Ttr greater than 20° C., which is introduced and then shaped, at least one of the mold portions having an area for transferring heat with the molding material, the heat transfer area including at least one sub-area consisting of at least one ferromagnetic material the Curie point Tc of which is between 20 and 800° C. and which is in contact with the molding material and/or with a non-ferromagnetic coating having a thermal conductivity greater than 30 W.m−1.K−1. A method for manufacturing a plastic or composite material product via of the molds according to the invention.
