Es ist ein Verfahren zur Herstellung einer Dichtung bekannt, bei dem ein Dichtungsprofil aus einem Kautschukmaterial, insbesondere einem synthetischen Kautschuk wie z. B. EPDM extrudiert wird. Anschließend wird das Dichtungsprofil vulkanisiert. Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung einer Dichtung zu schaffen, die gut positionierbar ist. Erfindungsgemäß wird zum Herstellen einer Dichtung (1), die insbesondere zum Abdichten eines Fensters eines Kraftfahrzeugs geeignet ist, zunächst ein Dichtungsprofil (5) extrudiert, an das anschließend ein Rastvorsprung (6) stoffschlüssig angespritzt wird. Bevorzugt wird dabei der Rastvorsprung (6) angespritzt, bevor das extrudierte Dichtungsprofil (5) auf Umgebungstemperatur abgekühlt ist.

Aufgabe der Erfindung ist es, ein Verfahren zur Herstellung einer Dichtung zu schaffen, die gut positionierbar ist. The object of the invention is to provide a method for producing a seal that is easy to position.
Diese Aufgabe wird mit einem Verfahren zur Herstellung einer Dichtung mit den Merkmalen des Patentanspruchs 1 gelöst. This object is achieved by a method for producing a seal having the features of
Erfindungsgemäß wird zum Herstellen einer Dichtung, die insbesondere zum Abdichten eines Fensters eines Kraftfahrzeugs geeignet ist, zunächst ein Dichtungsprofil extrudiert, an das anschließend ein Rastvorsprung stoffschlüssig angespritzt wird. Bevorzugt wird dabei der Rastvorsprung angespritzt, bevor das extrudierte Dichtungsprofil auf Umgebungstemperatur abgekühlt ist. Idealerweise wird der Rastvorsprung angespritzt, bevor das extrudierte Dichtungsprofil vollständig ausvulkanisiert ist. Beim Vulkanisieren werden die langkettigen Moleküle der Dichtungsmasse miteinander vernetzt. Hierdurch gehen die plastischen Eigenschaften der Dichtungsmasse verloren, sie wird mittels des Verfahrens der Vulkanisation vom plastischen in einen elastischen Zustand überführt. Wenn nun der Rastvorsprung vor der vollständigen Vulkanisation angespritzt wird, kann durch die Vulkanisation der Dichtungsmasse ein besserer Stoffschluss mit dem angespritzten Rastvorsprung erzielt werden. According to the invention, for producing a seal, which is suitable in particular for sealing a window of a motor vehicle, first a sealing profile is extruded, to which subsequently a latching projection is integrally molded. Preferably, the locking projection is molded on before the extruded sealing profile has cooled to ambient temperature. Ideally, the locking projection is molded on before the extruded sealing profile is completely vulcanized. During vulcanization, the long-chain molecules of the sealant are crosslinked with each other. As a result, the plastic properties of the sealant lost, it is transferred by means of the process of vulcanization of the plastic in an elastic state. Now, if the locking projection is molded prior to complete vulcanization, a better material connection with the molded locking projection can be achieved by the vulcanization of the sealant.
Dies ist ein neues Verfahren, um eine Dichtung mit einem Rastvorsprung herzustellen. Normalerweise müssen alle Bereiche einer Dichtung direkt mit dem Dichtungsprofil extrudiert werden. Alle nicht benötigten Bereiche werden dann von dem Dichtungsprofil ausgeklinkt bzw. abgeschnitten, sodass nur die Abschnitte des extrudierten Dichtungsprofils übrig bleiben, die benötigt werden. Nachteiligerweise entstehen dabei abgeschnittene Reste, die als Abfall entsorgt werden müssen. Auch ist das sorgfältige Ausklinken bzw. Ausschneiden der nicht benötigten Bereiche aufwändig. Das erfindungsgemäße Verfahren ermöglicht das Anbringen eines Rastvorsprungs, ohne dass das extrudierte Dichtungsprofil nachträglich beschnitten werden muss. Beim Anspritzen des Rastvorsprungs entstehen keinerlei Abfälle. This is a new method to make a seal with a locking projection. Normally, all areas of a gasket must be extruded directly with the gasket profile. Any unneeded areas are then unlatched from the weatherstrip, leaving only the portions of the extruded weatherstrip that are needed. Disadvantageously arise thereby cut off remnants, which must be disposed of as waste. Also, the careful notching or cutting the unneeded areas consuming. The inventive method allows the attachment of a locking projection, without the extruded sealing profile must be subsequently trimmed. When sprinkling the locking projection no waste.
Der angespritzte Rastvorsprung ermöglicht es, die Dichtung genau an einem Bauteil mit einer Ausnehmung zu positionieren. Dabei müssen natürlich der Rastvorsprung und die Ausnehmung aufeinander abgestimmt sein, sodass der Rastvorsprung genau in die Ausnehmung passt, ohne dass der Rastvorsprung mit unnötigem Spiel in der Ausnehmung gehalten ist. The molded locking projection makes it possible to position the seal exactly on a component with a recess. Of course, the latching projection and the recess must be coordinated with each other, so that the latching projection fits exactly into the recess, without the latching projection is held with unnecessary play in the recess.
Bevorzugt wird das Dichtungsprofil in einem Endlosverfahren als Endlosdichtung extrudiert, wobei die Endlosdichtung anschließend in die Dichtungsprofile zerschnitten wird. Dabei werden die Rastvorsprünge vorteilhafterweise in regelmäßigen Abständen an die Endlosdichtung angespritzt werden, bevor die Endlosdichtung in die Dichtungsprofile zerschnitten wird. Dies ermöglicht eine vollautomatisierte Herstellung mehrerer Dichtungen, sodass die Dichtungen bei größeren Stückzahlen sehr kosteneffizient hergestellt werden können. Idealerweise wird die Dichtung auf einer Fertigungslinie gefertigt, die hintereinander die Endlosdichtung extrudiert, die Rastvorsprünge anspritzt und anschließend die Endlosdichtung in die Dichtungsprofile zerschneidet. Preferably, the sealing profile is extruded in an endless process as an endless seal, wherein the endless seal is then cut into the sealing profiles. In this case, the latching projections are advantageously injected into the endless seal at regular intervals before the endless seal is cut into the sealing profiles. This allows fully automated manufacturing of multiple seals, allowing the seals to be produced very cost-efficiently for larger volumes. Ideally, the seal is manufactured on a production line, which extrudes the endless seal one behind the other, injects the locking projections and then cuts the endless seal into the sealing profiles.
Idealerweise besteht der Rastvorsprung aus dem gleichen Material wie das Dichtungsprofil. Insbesondere wenn der Rastvorsprung angespritzt wird, bevor das extrudierte Dichtungsprofil kalt und ausvulkanisiert ist, entsteht eine sehr belastbare stoffschlüssige Verbindung zwischen dem Rastvorsprung und dem extrudierten Dichtungsprofil. Dabei ist nur das äußere Material des Dichtungsprofils maßgeblich, ob in dem äußeren Material ein sogenannter Carrier, also eine metallische Verstärkung, eingebettet ist, ist hier nicht maßgeblich. Beispielsweise kann das Material ein EPDM (Ethylen-Propylen-Dien-Kautschuk) sein. EPDM ist ein terpolymeres Elastomer (Gummi) und somit ein synthetischer Kautschuk. Es wird wegen seiner hohen Elastizität und guten chemischen Beständigkeit häufig für Dichtungen verwendet. Ideally, the locking projection consists of the same material as the sealing profile. In particular, when the locking projection is molded, before the extruded sealing profile is cold and vulcanized, creates a very strong cohesive connection between the locking projection and the extruded sealing profile. In this case, only the outer material of the sealing profile is decisive, whether in the outer material a so-called carrier, so a metallic reinforcement, embedded, is not relevant here. For example, the material may be an EPDM (ethylene-propylene-diene rubber). EPDM is a terpolymeric elastomer (rubber) and thus a synthetic rubber. It is often used for seals because of its high elasticity and good chemical resistance.
