Patent ID: 8668802

Claim:
A method for electromagnetic welding of moulded parts, comprising the steps of: A) providing a mould; B) placing at least two moulded parts for coupling in the mould, wherein at least a contact surface between the moulded parts comprises a thermally activated coupling means and an induction-sensitive component; C) activating the coupling means by heating the induction-sensitive component by means of an inductor, wherein the inductor is situated outside the mould such that the inductor does not come into contact with the mould in order to enable a mutual movement between the inductor and the moulded parts that defines a direction of welding, wherein the inductor comprises an electrical conductor which, under alternating voltage, generates an electromagnetic field which is substantially cylindrical in at least said direction of welding, and wherein the electromagnetic field of the inductor reaches the contact surface between the moulded parts through a wall of the mould; and D) pressing the moulded parts together in the configuration defined by the mould, wherein the moulded parts are coupled by the thermally activated coupling means.
