Abstract

MOULE EN DEUX PARTIES, POUR ENROBER UN COMPOSANT DE MATIERE PLASTIQUE EN FUSION. LES DEUX MOITIES DU MOULE FORMENT DES CHAMBRES SEPAREES, MAIS COMMUNIQUANT ENTRE ELLES ET DESTINEES A LOGER UN COMPOSANT ET UN TRONCON D'UN FIL CONDUCTEUR NON AXIAL DE CONNEXION DE CE COMPOSANT. DE LA MATIERE PLASTIQUE EN FUSION, INTRODUITE DANS LE MOULE POUR ENROBER LE COMPOSANT, SE FIXE AUTOUR DES FILS DE CONNEXION DE CE DERNIER, MAIS PEUT EN ETRE AISEMENT RETIREE. DOMAINE D'APPLICATION : ENROBAGE DE CONDENSATEURS CERAMIQUES, ETC.MOLD IN TWO PARTS, FOR COATING A COMPONENT WITH FUSION PLASTIC MATERIAL. THE TWO HALVES OF THE MOLD FORM SEPARATE CHAMBERS, BUT COMMUNICATE BETWEEN THEM AND INTENDED TO HOUS A COMPONENT AND A TRUNK OF A NON-AXIAL CONDUCTING WIRE FOR CONNECTING THIS COMPONENT. FUSION PLASTIC MATERIAL, INTRODUCED INTO THE MOLD TO COVER THE COMPONENT, FIXES AROUND THE LATTER'S CONNECTING WIRES, BUT CAN BE EASILY REMOVED. FIELD OF APPLICATION: COATING OF CERAMIC CAPACITORS, ETC.
