Abstract

LE NOUVEAU MOULE, CONSTITUE EN DEUX PARTIES 1 ET 2 QUI COOPERENT, EST ESSENTIELLEMENT CARACTERISE EN CE QUE LA DEMI-MAQUETTE (OU CONTRE-MOULE) INFERIEURE 10 REPOSE SUR UNE COUCHE DE SILICONE PUR OU ANALOGUE SERVANT D'ECRAN CALORIFIQUE ET JOUXTANT UNE COUCHE DE SILICONE - OU ANALOGUE - CHARGE A 80-120 DE POUDRE D'AL, L'ENSEMBLE ETANT ISOLE DANS UN CADRE 12 EN POLYPROPYLENE OU ANALOGUE ET LA STRUCTURE EXTERNE 7 PAR EXEMPLE EN ALUMINIUM. LA MAQUETTE EST REALISEE EN SILICONE CHARGEE A 20-30DE POUDRE D'AL. LA MATIERE A MOULER 13 EST INTRODUITE DANS L'ESPACE CREE ENTRE LES DEUX PARTIES DU CONTRE-MOULE. LE MOULAGE PAR L'ACTION DE LA HAUTE FREQUENCE EXERCEE SELON LES FLECHES 14 EST RAPIDE ET LE REFROIDISSEMENT SE PRODUIT TRES VITE DU FAIT DE LA STRUCTURE INTERNE PRECITEE. APPLICATION AU MOULAGE PAR HAUTE FREQUENCE D'OBJETS DE TOUTES CONFORMATIONS, AVEC OU NON FORMATION DE PEAUX SUPERFICIELLES.
