Abstract:
A method of producing a shielding casing for mechanically protecting and electromagnetically shielding an electronic functional unit, in which there is provided a sealing and shielding profile section which fills gap between a first and second adjoining casing portions and which comprises pasty material applied under pressure from a coordinate-controlled applicator needle or nozzle directly on to the first casing portion which then sets elastically, adhering thereto in self-supporting relationship, comprising: producing the sealing and shielding profile section by simultaneously applying at least a first material with material properties which are adapted to a good shielding action and a second material which sets elastically, with material properties which are adapted to a good sealing action, from the applicator needle or nozzle which is provided with at least a first and a second passage, whereby the second material adheres firmly to the first material and wherein one of the first and second materials forms a base portion and the other of the first and second materials forms a layer that at least partially surrounds the base portion.
