MOULD, METHOD OF MOULD PRODUCTION AND METHOD OF PRODUCTION OF ARTICLE FROM PLASTIC OR COMPOSITE MATERIAL WITH HELP OF THIS MOULD Russian patent published in 2015 - IPC H05B33/02 B29C33/06 B29C35/08 B22D15/00 

Abstract RU 2565703 C2

FIELD: process engineering.

SUBSTANCE: invention discloses the induction-heated mould including at least one lower part and one upper part to confine the cavity. Moulding material is loaded into the mould, heated to temperature Ttr higher than 20°C and moulded therein. Note here that at least one of mould parts includes the zone of heat transfer with forming material. Heat transfer zone includes at least one subzone of heat transfer made of at least one ferromagnetic material with Curie point Tc varying from 20 to 800°C to contact with forming material and/or with non-ferromagnetic coating with specific heat conductivity of 30 W·m-1·K-1.Besides, invention covers the mould production process and method of article production from plastic or composite material.

EFFECT: simplified production of mould and its design, ease of modulation of unknown magnetic and/or thermal characteristics.
