Title (DE) VERFAHREN ZUR HERSTELLUNG EINES BESCHICHTETEN BAUTEILS
(EN) METHOD FOR PRODUCING A COATED COMPONENT
(FR) PROCEDE DE FABRICATION D'UN COMPOSANT REVETU
Abstract:
(DE) Es wird ein Verfahren zur Herstellung eines mit einer Thermoplastschicht (30) beschichteten Bauteils (10) vorgeschlagen, wobei das Verfahren umfasst: a) Bereitstellen des Bauteils (10), b) Aufbringen einer Zwischenschicht (20) aus einem Kunststoff auf wenigstens einem Teil des Bauteils (10), c) Durchführen einer Plasmabehandlung der Zwischenschicht (20) mit einem Plasmagas, wobei die Moleküle oder die Struktur der Moleküle der Zwischenschicht (20) zumindest an der Oberfläche der Zwischenschicht (20) modifiziert werden, und d) Spritzgießen der Thermoplastschicht (30) derart, dass die Thermoplastschicht (30) und das mit der Zwischenschicht (20) versehene Bauteil (10) kraftschlüssig aneinander haften.
(EN) The invention relates to a method for producing a component (10) coated with a thermoplastic layer (30). This method consists of: a) preparing the component (10); b) applying an intermediate layer (20) made of a synthetic material onto at least a portion of the component (10); c) subjecting the intermediate layer (20) to a plasma treatment with a plasma gas, during which the molecules or the structure of the molecules of the intermediate layer (20) are modified at least on the surface of the intermediate layer (20), and; d) injection molding the thermoplastic layer (30) in such a manner that the thermoplastic layer (30) and the component (10) provided with the intermediate layer (20) adhere to one another in a non-positive manner.
(FR) L'invention concerne un procédé de fabrication d'un composant revêtu (10) au moyen d'une couche thermoplastique (30), consistant a) à se munir du composant (10) ; b) à appliquer une couche intermédiaire plastique (20) sur au moins une partie du composant (10) ; c) à réaliser un traitement plasma de la couche intermédiaire (20) au moyen d'un gaz plasma, les molécules ou les structures des molécules de la couche intermédiaire (20) étant modifiées au moins à la surface de la couche intermédiaire (20) ; et, d) à mouler par injection la couche thermoplastique (30) de telle manière que la couche thermoplastique (30) et le composant (10) pourvu de la couche intermédiaire (20) adhèrent l'un à l'autre.
