Description
Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines Kunststofformteils in einer Ausbildung gemäss dem Oberbegriff des Patentanspruchs 1.The The invention relates to a method for producing a plastic molding in an education according to the preamble of claim 1.
Kunststofformteile mit einem transparenten Fenster finden Einsatz bei verschiedenen Produkten, z.B. bei Kommunikationssendegeräten wie Mobiltelefonen und bei vielen Produkten der Consumer electronics.Plastic moldings with a transparent window find use at different Products, e.g. in communication terminals such as mobile phones and for many consumer electronics products.
Dabei werden vielfach transparente Spritzgusskunststoffteile eingesetzt. Alternativ können transparente Fensterelemente für die vorgenannten Einsatzzwecke hergestellt werden, indem Halbzeuge gefertigt werden, um aus einer Plattenware Fensterelemente auszuschneiden bzw. auszufräsen und diese als separate Bauteile in entsprechende Kunststofformteile einzusetzen.there transparent plastic injection molded parts are often used. Alternatively, transparent Window elements for the aforementioned purposes are produced by making semi-finished products be used to cut out window elements from a plate product or to be milled out and these as separate components in corresponding plastic moldings use.
Nachteilig hierbei ist, dass die Montage eines derartigen Fensterelementes durch Kleben mittels Adhesiven, durch wärmegesteuerte Klebeprozesse oder durch Schweissen oder Nieten erfolgt. Dies kann dazu führen, dass bei der Montage solcher Teile sowohl Bauteiltoleranzen des Kunststofformteils (z.B. eines Mobiltelefongehäuses) als auch die Toleranzen des zu montierenden Fensterelementes zu berücksichtigen sind, was sowohl bauteilseitig (+/– 0,15 mm) als auch bei dem Fensterelement zu Toleranzen von 0,1-0,2 mm führen kann. Das zieht Spalte im Bereich des anzuordnenden Fensterelementes nach sich, was nicht nur aus optischen Gründen unerwünscht ist, sondern auch Orte für Schmutzansammlungen u.dgl. darbietet. Neben den Spalten kann es auch zu Höhenunterschieden und mithin zu Dickentoleranzen des mit dem Fenster zu versehenen fertigen Kunststofformteils kommen.adversely Here is that the assembly of such a window element by gluing with adhesives, heat - controlled gluing processes or done by welding or riveting. This can cause that during assembly of such parts both component tolerances of the plastic molding (e.g. a mobile phone case) as well as to consider the tolerances of the window element to be mounted are what both component side (+/- 0.15 mm) and in the Window element can lead to tolerances of 0.1-0.2 mm. That pulls in the column Area of the window element to be arranged, which is not only for visual reasons undesirable is, but also places for Dirt accumulations and the like. presents. It can be next to the columns also to height differences and consequently to thickness tolerances of the window to be provided finished plastic molding come.

Es ist Aufgabe der vorliegenden Erfindung, das Verfahren zur Herstellung eines Formteils der eingangs genannten Art dahingehend zu verbessern, dass ein Fensterteil möglichst spaltfrei in das Formteil zu integrieren ist.It The object of the present invention is the process for the preparation a molding of the type mentioned above to improve that a window part as possible is to integrate gap-free in the molding.
Die Aufgabe wird gelöst durch ein Verfahren mit den Merkmalen des Anspruchs 1.The Task is solved by a method having the features of claim 1.
Damit ist ein Formteil zur Verfügung gestellt, bei dem spaltfrei sowie flächenbündig und formschlüssig das Fensterteil vorzusehen ist. Dazu ist zunächst der Fensterträger vorgesehen, der als Basisbauteil dient. Dieser Fensterträger kann sich bereichsweise um die Aussparung erstrecken, kann aber auch vollflächig insgesamt ein Basisteil des Formteils sein und so z.B. der Geometrie eines Gehäuses eines Mobiltelefons insgesamt folgen. Auf diese Fensterträger als Basisbauteil kann dann das Fensterteil gelegt und z.B. durch Kleben mittels Adhesiven, durch wärmegesteuerte Klebeprozese oder Schweissen mit diesem verbunden werden. Der Fensterträger kann z.B. aus Materialien wie PC, PC/ABS, Polyamid (PA), PP, Polyurethan bestehen, wobei als Fensterelement Materialien wie Glas, Holz, Metall, Keramik und Kunststoff verwendet werden können. Die Anforderung an ein Displayfenster für z.B. ein Mobiltelefon hat eine sehr hohe Kratzfestigkeit. Auf diesen Fensterträger kann dann eine Beschichtung aufgebracht werden aus z.B. einem transparenten Kunststoffmaterial, die mithin das sichtbare Gehäuse darbietet und flächenbündig an das Fensterteil heranreicht und mit diesem randseitig einen innigen Verbund eingeht. Im fertigen Zustand ist das Formteil daher mit einer Aussparung zur Anordnung des Fensterteils versehen, die sich teilweise in dem Fensterträger und teilweise in der aufzubringenden Beschichtung erstreckt. Insgesamt ist damit in einem zweiten Prozeßschritt das vormontierte Bauteil, also der Fensterträger, im Spritzgießverfahren so mit der Beschichtung zu umspritzen, dass ein flächenbündiger und formschlüssiger Verbund insgesamt entsteht, und zwar ohne Spaltbildung. Dazu besteht vorzugsweise der Fensterträger aus einem Kunststoffmaterial und die Beschichtung aus einem anderen Kunststoffmaterial.In order to is a molding available in the gap-free as well as flush and form-fitting the Window part is provided. For this purpose, the window support is initially provided which serves as a base component. This window support can be partially extend around the recess, but can also over the entire area be a base part of the molding and so e.g. the geometry of a housing of a mobile phone overall. On this window support as Base member can then put the window part and e.g. by gluing by means of adhesives, by heat-controlled Gluing process or welding to be connected with this. The window carrier can e.g. made of materials such as PC, PC / ABS, polyamide (PA), PP, polyurethane exist as a window element materials such as glass, wood, metal, Ceramic and plastic can be used. The request for a Display window for e.g. A mobile phone has a very high scratch resistance. On this windows support then a coating can be applied from e.g. a transparent one Plastic material, which therefore offers the visible housing and flush with the Window part comes close and with this edge an intimate Verbund enters. In the finished state, the molding is therefore with a recess for the arrangement of the window part provided, which is partly in the window carrier and partially extending in the coating to be applied. All in all is thus in a second process step the preassembled component, so the window carrier, in injection molding so to coat with the coating that a flush and form-fitting Composite arises altogether, without gap formation. There is preferably the window carrier made of a plastic material and the coating of another plastic material.
Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus weiteren Ansprüchen, der nachfolgenden Beschreibung und der Zeichnung. In der einzigen Zeichnung ist ein Ausführungsbeispiel eines Formteils nach der Erfindung dargestellt.Further advantageous embodiments of the invention will become apparent from further claims, the following description and the drawing. In the only one Drawing is an embodiment of a Shaped part according to the invention.
