Title
(DE) VERFAHREN ZUR HERSTELLUNG EINER DROSSELKLAPPE IN EINEM DURCHGEHENDEN DROSSELKLAPPENSTUTZEN DURCH SPRITZGIESSEN VON KUNSTSTOFF
(EN) METHOD FOR PRODUCING A THROTTLE VALVE IN A CONTINUOUS THROTTLE BODY BY PLASTIC INJECTION MOLDING

Abstract
(DE)
In einem ersten Schritt wird im Drosselklappenstutzen (2) eine umlaufende, ringförmige Nut (3) eingearbeitet. Anschliessend werden ein erster Stempel (4) und ein zweiter Stempel (5) in den Drosselklappenstutzen (2) eingefahren und ein erster Kunststoff in einen dadurch gebildeten zylindrischen ersten Hohlraum (6) in aufgeschmolzenem Zustand eingeführt und zur Aushärtung gebracht. Dabei entsteht ein Kunststoffeinsatz (10). Anschliessend werden der erste Stempel (4) und der zweite Stempel (5) aus dem Drosselklappenstutzen (2) herausgefahren und ein dritter Stempel (11) und ein vierter Stempel (12) in den Drosselklappenstutzen (2) eingebracht. Zwischen ihnen wird ein zweiter Hohlraum (14) gebildet, der mit einem zweiten Kunststoff ausgefüllt wird und dadurch die Drosselklappe (1) bildet.
(EN)
In a first step, a peripheral, annular groove (3) is incorporated into the throttle body (2). A first male mold (4) and a second male mold (5) are inserted in the throttle body (2) and a first plastic material is introduced in the molten state into the cylindrical first cavity (6) thereby formed and allowed to cure, thereby producing a plastic insert (10). The first male mold (4) and the second male mold (5) are withdrawn from the throttle body (2) and a third male mold (11) and a fourth male mold (12) are introduced into the throttle body (2). Between these two molds a second cavity (14) is formed which is filled with a second plastic material, thereby producing the throttle valve (1).
(FR)
Dans une première étape, une rainure annulaire périphérique (3) est formée dans un corps de papillon (2). Ensuite, un premier poinçon (4) et un deuxième poinçon (5) sont insérés dans ce corps de papillon (2). Une première matière plastique est injectée à l'état fondu à l'intérieur d'une première cavité cylindrique (6) ainsi formée puis est amenée à durcir. On obtient alors une pièce rapportée en matière plastique (10). Le premier poinçon (4) et le deuxième poinçon (5) sont ensuite retirés du corps de papillon (2) puis un troisième poinçon (11) et un quatrième poinçon (12) sont introduits dans ce corps de papillon (2). Entre ces deux poinçons se forme une seconde cavité (14) qui est remplie d'une seconde matière plastique, de façon à permettre la formation du papillon (1).
