Patent attributes
A method for electromagnetic welding of molded parts wherein a mold and at least two molded parts for coupling are placed in the mold, wherein at least a contact surface between the molded parts comprises a thermally activiated coupling means and an induction-senstive component. The coupling means is activated by heating the induction-senstive component by means of an inductor. The inductor comprises an electrical conductor which, under alternating voltage, generates an electromagnetic field which is substantially cylindrical in at least a direction of welding. The molded parts are pressed together in the configuration defined by the mold, wherein the molded parts are coupled by the thermally activated coupling means. Also disclosed is an assembly of molded parts, an inductor, an assembly of the inductor with an alternating current generator, and a device for electromagnetic welding.
