Abstract

Die Erfindung geht aus von einem Verfahren zur Herstellung einer Mischvorrichtung (10) für eine Abgasnachbehandlungsvorrichtung zum Nachbehandeln von Abgasen eines Verbrennungsmotors.The invention is based on a method for producing a mixing device (10) for an exhaust aftertreatment device for after-treatment of exhaust gases of an internal combustion engine.

Es wird vorgeschlagen, dass aus einem plattenförmigen Grundmaterial wenigstens ein Trägerelement (11) mit wenigstens einem einstückig angesetzten Mischelement (12) gebildet wird, wobei das Mischelement (12) und das Trägerelement (11) entsprechend ihrem späteren Einsatzzweck gebogen werden.It is proposed that at least one carrier element (11) with at least one integrally attached mixing element (12) is formed from a plate-shaped base material, wherein the mixing element (12) and the carrier element (11) are bent in accordance with their later intended use.

Die Erfindung betrifft ferner eine Mischvorrichtung für eine Abgasnachbehandlungsvorrichtung zum Nachbehandeln von Abgasen eines Verbrennungsmotors sowie eine Anordnung mit einer solchen Mischvorrichtung.
