Abstract

A moulded article partic,. suitable for in car interiors, e.g. a door covering, half shelf etc., consists of an injection moulding with (at least on one side) a fabric (cloth or knitware) decorative layer; it has a plastic film between the moulding and fabric and this is bonded to both. The film is preferably thermoplastic. The product is made by passing together the fabric and film, cutting the laminate obtd. into sheets, placing a sheet in an injection mould, and injecting the shot. The process combines the shape with bonds, whilst the film acts as a barrier to prevent the injected polymer from flowing through the fabric. The cut sheets are best performed before the injection. Such preforming can be carried out by vacuum/thermoforming and it gives the fabric the desired shape, besides preventing pressure peaks from occurring which damage the final appearance. ADVANTAGE - The prod. is simple and inexpensive. It is technologically satisfactory and aesthetically suitable for the applications

Description

Die Erfindung bezieht sich auf ein Formteil, insbesondere für den Innenraumbereich von Fahrzeugen, wie Türverkleidung, Fensterschlüssel, Hutablage u. dgl. sowie auf ein Verfahren zum Herstellen eines solchen Formteils.The invention relates to a molded part, in particular for the Interior area of vehicles, such as door panels, window keys, Parcel shelf u. Like. And to a method for producing such Molding.

Der Erfindung liegt die Aufgabe zugrunde, ein Formteil der genannten Art zu schaffen, das einfach und kostengünstig ist, den technischen Anforderungen genügt und ästhetisch ansprechend ist. Ferner ist es Aufgabe der Erfindung ein Verfahren zum Herstellen eines solchen Formteils aufzuzeigen.The invention has for its object a molding of the above To create the kind that is simple and inexpensive, the technical Requirements meet and is aesthetically pleasing. Furthermore, it is The object of the invention is a method for producing such To show molded parts.

Das erfindungsgemäße Formteil besteht aus einem Kunststoff-Spritzgußkörper, der zumindest an seiner Stichseite eine Dekorauflage aus Textilmaterial (Gewebe, Gewirke, Gestricke) und zwischen dem Kunststoff-Spritzgußkörper und dem Textilmaterial eine Kunststoffolie als Zwischenlage aufweist, wobei zwischen dem Textilmaterial und der Kunststoffolie einerseits und zwischen der Kunststoffolie und dem Spritzgußkörper andererseits eine festhaftende Flächenverbindung besteht. The molded part according to the invention consists of a plastic injection molded body, at least on its stitch side from a decorative pad Textile material (woven, knitted, crocheted) and between the plastic injection molded body and the textile material a plastic film has as an intermediate layer, between the textile material and the plastic film on the one hand and between the plastic film and the injection molded body, on the other hand, a firmly adhering surface connection consists.  

Ein solches erfindungsgemäß ausgebildetes Formteil besitzt ein formschönes, den Wünschen der Käuferschaft entgegenkommendes Aussehen und ist problemlos herzustellen. Dabei ist die aus einer Kunststoffolie gebildete Zwischenlage von besonderer Bedeutung, weil diese gewissermaßen als Verbindungselement zwischen dem Textilmaterial und dem Kunststoff-Spritzgußkörper wirkt.Such a molded part designed according to the invention has an elegant, Appearance to meet the wishes of the buyers and is easy to manufacture. It is made of a plastic film formed liner of particular importance because of this to a certain extent as a connecting element between the textile material and the plastic injection molded body acts.

Das Verfahren zum Herstellen eines Formteils zeichnet sich dadurch aus, daß auf ein bahnförmiges Textilmaterial eine Kunststoffolie im Durchlauf aufkaschiert wird, daß aus dem so gewonnenen Laminat dem zu fertigenden Formteil entsprechende Zuschnitte angefertigt werden und daß die Zuschnitte jeweils in die Formkavität eines Spritzgußwerkzeuges eingelegt und mit einer plastifizierten Kunststoffmasse hinterspritzt werden.The process for producing a molded part is characterized by this from that a plastic film on a web-shaped textile material is laminated in the run that from the laminate thus obtained cuts corresponding to the molded part to be produced and that the blanks each in the mold cavity of an injection molding tool inserted and with a plasticized plastic mass be injected.

Auf diese Weise lassen sich besonders einfach und kostengünstig ästhetisch ansprechende Formteile für den Innenraumbereich von Fahrzeugen herstellen. Dabei kann beim Aufkaschieren der Kunststoffolie auf das Textilmaterial auf klassische Kaschierverfahren und herkömmliche Kaschiervorrichtungen zurückgegriffen werden. Durch das Hinterspritzen wird das Textilmaterial nebst der daran haftenden Kunststoffolie in die jeweilige Oberflächenkontur des Formteils gezwungen, die nach dem Erstarren der Kunststoff-Spritzgußmasse auch zwangsläufig beibehalten wird. Beim Hinterspritzen geht die heiße Kunststoff-Spritzgußmasse zudem einen innigen Verbund mit der Kunststoffolie ein. Die Kunststoffolie wirkt nicht nur als Verbundschicht (Verbindungselement) zwischen dem Textilmaterial und dem Spritzgußkörper sondern auch als Sperrschicht, die verhindert, daß das plastifizierte Kunststoffmaterial beim Spritzgießen das Textilmaterial durchsetzt.In this way, it can be aesthetically particularly simple and inexpensive attractive molded parts for the interior of vehicles produce. The plastic film can be laminated on the textile material on classic laminating processes and conventional Laminating devices can be used. By injecting becomes the textile material along with the plastic film adhering to it forced into the respective surface contour of the molded part, which after inevitably maintain the solidification of the plastic injection molding compound becomes. The hot plastic injection molding compound is used for back injection also an intimate bond with the plastic film. The Plastic film not only acts as a composite layer (connecting element) between the textile material and the injection molded body but also as a barrier layer that prevents the plasticized plastic material penetrates the textile material during injection molding.

Bevorzugterweise werden die Zuschnitte jeweils zunächst der Oberflächenkontur des Formteils entsprechend vorgeformt und erst hiernach hinterspritzt. Dabei kann vorteilhafterweise eine thermoplastische Halbhartfolie als Kunststoffolie verwendet werden. The blanks are preferably first of all the surface contour of the molded part preformed accordingly and only afterwards back injected. A thermoplastic can advantageously be used Semi-rigid film can be used as a plastic film.  

Diese Maßnahmen tragen wesentlich zur Qualitätsverbesserung eines danach ausgebildeten Formteils bei. Durch das Vorverformen, was in herkömmlichen Vakuum-Tiefzieh-Vorrichtungen problemlos durchzuführen ist, weist das Textilmaterial bereits vor dem Hinterspritzen die Oberflächenkontur des jeweiligen Formteils auf. Die vorgeformte Kunststoffolie kann damit als Druckverteiler beim Hinterspritzen zur Vermeidung örtlicher Druckspitzen und Schubspannungen durch die Spritzgußmasse wirken. Druckspitzen könnten nämlich dazu führen, daß das Textilmaterial örtliche, das angenehme Erscheinungsbild beeinträchtigende Druckstellen aufweist, während Schubspannungen zu unerwünschten Faltenbildungen an den Sichtseiten der Formkörper führen könnten.These measures contribute significantly to the quality improvement of a then trained molded part. By preforming what in conventional vacuum deep-drawing devices without any problems is, the textile material already has the Surface contour of the respective molded part. The preformed plastic film can thus be used as a pressure distributor when injecting to avoid local pressure peaks and shear stresses caused by the injection molding compound Act. Pressure peaks could cause the textile material local, which affects the pleasant appearance Has pressure points, while shear stresses lead to undesirable wrinkles could lead to the visible sides of the molded body.
