Abstract: An improved induction sealing device (300) is presented. The device (300) comprises a main body (302), a magnetic field concentrator (306) held in said main body (302) and a conductive element (304). One or several protrusions (314a, 314b) of said magnetic field concentrator (306) cooperate with one or several indentations or openings (312a, 312b) in said main body (302) such that said magnetic field concentrator (306) and said main body (302) is securely bonded together.

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).

Abstract: A magnetic insert for enhancing the magnetic field of an induction heating device is provided. The magnetic insert is manufactured by use of a composition comprising a moldable polymer matrix and a soft magnetic material.

Abstract: The present invention relates to an induction sealing device for heat sealing packaging material for producing sealed packages.

Abstract: A water-soluble methyl cellulose ether, having a flocculation point below 100° C., is manufactured by reacting methyl chloride and a cellulose activated by mercerizing the cellulose with aqueous alkali in the presence of a C2-C3 alkyl chloride as a reaction medium at a temperature from 65° C. to 90° C. and at a pressure from 3 to 15 bar. The weight ratio between the cellulose and the C2-C3 alkyl chloride is normally from 1:1 to 1:5. The use of the reaction medium makes it possible to produce at a low pressure methyl cellulose ether at a good rate.
