Beschreibung
Zusammenfassung:	An improved induction sealing device is presented. The device comprises a main body (302, 402a, 402b), a magnetic field concentrator (306, 406a, 406b) held in the main body and a conductive element (304, 404a, 404b) also held in the main body (302, 402a, 402b). The magnetic field concentrator (306, 406a, 406b) is injection molded in said main body (302, 402a, 402b). For this purpose the main body (302, 402a, 402b) is provided with at least one hole (312a, 312b) to gate material for forming said magnetic field concentrator (306, 406a, 406b) into an interior of said main body (302, 402a, 402b). L'invention concerne un dispositif d'étanchéité par induction amélioré. Le dispositif comprend un corps principal (302, 402a, 402b), un concentrateur de champ magnétique (306, 406a, 406b) retenu dans le corps principal et un élément conducteur (304, 404a, 404b) également retenu dans le corps principal (302, 402a, 402b). Le concentrateur de champ magnétique (306, 406a, 406b) est moulé par injection dans ledit corps principal (302, 402a, 402b). Dans ce but, le corps principal (302, 402a, 402b) comprend au moins un orifice (312a, 312b) pour bloquer le matériau afin de former ledit concentrateur de champ magnétique (306, 406a, 406b) dans un intérieur dudit corps principal (302, 402a, 402b).
