The invention relates to a method for producing a shielding case (4) whereby a sealing and shielding section (9) which fills out a gap between first and second adjoining case parts (1, 2) is provided. Said sealing and shielding section (9) is applied directly onto the first case part as a pastelike material under pressure using a co-ordinate-controlled application device (5) equipped with an application needle or nozzle, then sets elastically, unsupported on said first case part, adhering thereto. Said sealing and shielding section is produced by simultaneously applying at least one first material (8a) with good sealing properties and one second material (8b) with good shielding properties using the application needle or nozzle (6) which has at least one first and one second channel (6a, 6b), so that said second material adheres to said first material.

L'invention concerne un procédé permettant de fabriquer un boîtier de blindage (4), qui présente, entre une première et une seconde partie adjacentes (1, 2), une fente remplie par un profilé d'obturation et de blindage (9) constitué d'un matériau pâteux. Ce dernier est appliqué sous pression, au moyen d'un dispositif applicateur (5) guidé par un système de coordonnées et comportant une aiguille ou un embout d'application, directement sur la première partie du boîtier, au niveau de laquelle il se solidifie et adhère sans être supporté. Afin de produire le profilé d'obturation et de blindage, on applique simultanément au moins un premier matériau (8a) ayant de bonnes propriétés d'obturation et un second matériau (8b) ayant de bonnes propriétés de blindage au moyen de l'aiguille ou de l'embout d'application (6), qui comporte au moins un premier et un second canal (6a, 6b), de façon que le second matériau adhère solidement sur le premier.
