Abstract
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).
