20100206469 | METHOD AND DEVICE FOR ELECTROMAGNETIC WELDING OF MOULDED PARTS - A method for electromagnetic welding of moulded parts wherein a mould and at least two moulded parts for coupling are placed in the mould, wherein at least a contact surface between the moulded 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 moulded parts are pressed together in the configuration defined by the mould, wherein the moulded parts are coupled by the thermally activated coupling means. Also disclosed is an assembly of moulded parts, an inductor, an assembly of the inductor with an alternating current generator, and a device for electromagnetic welding. | 08-19-2010 |
