Patent

CA 2752422

The invention relates to a method for producing a high-temperature insulating profile strip (30) comprising a foamed insulating core (31) and an enclosure (32) surrounding the insulating core (31), with the following steps: forming the insulating core (31) by introducing a foam material into a first moulding tool; removing the insulating core (31) from the first moulding tool after hardening; introducing the insulating core (31) into a second moulding tool; injecting a casing material into the second moulding tool for forming the casing (32) surrounding the insulating core (31), and removing the profile strip (30) from the second moulding tool after the expiration of a hardening phase. The invention also relates to a moulding tool for carrying out said method and to a profile strip (30) produced according to said method.

PROCÉDÉ DE PRODUCTION D'UN PROFILÉ, OUTIL DE FORMAGE POUR CE PROCÉDÉ, ET PROFILÉ RÉALISÉ PAR CE PROCÉDÉ L'invention porte sur un procédé pour produire un profilé (30) à capacité thermo-isolante élevée, comprenant un noyau isolant (31) de mousse et une enveloppe (32) entourant le noyau isolant (31). Les étapes de ce procédé consistent à former le noyau isolant (31) en introduisant un matériau moussant dans un premier outil de formage, à extraire le noyau isolant (31) du premier outil de formage après durcissement, à placer du noyau isolant (31) dans un second outil de formage, à injecter un matériau d'enveloppe dans le second outil de formage pour former l'enveloppe (32) entourant le noyau isolant (31), puis à extraire le profilé (30) du second outil de formage après écoulement d'une période de durcissement. L'invention concerne en outre un outil de formage pour la mise en uvre de ce procédé, ainsi qu'un profilé (30) réalisé selon ce procédé.
