Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines Dekorelements gemäß den Merkmalen des Patentanspruches 1.The The present invention relates to a process for producing a Decorative element according to the features of claim 1.
Hochwertige Fahrzeuge sind im Fahrgastraum üblicherweise mit einer ganzen Reihe von Dekorelementen versehen. Oftmals werden hierfür Materialien, wie z. B. Holz, Carbonfaserstrukturen, Gewebe aus Aluminiumfäden o. ä. verwendet. Aufgrund seiner Maserung weist beispielsweise Holz einen ganz typischen optischen Eindruck auf. Selbiges gilt auch für künstlich hergestellte dreidimensionale Strukturen, wie z. B. Carbonfaserstrukturen oder Gewebe aus Aluminiumfäden.High quality Vehicles are common in the passenger compartment provided with a whole set of decorative elements. Often therefor Materials, such. As wood, carbon fiber structures, fabric of aluminum threads o. Ä. Used. Because of its grain, wood, for example, is a very typical one optical impression. The same applies to artificially produced three-dimensional structures, such as As carbon fiber structures or fabric of aluminum filaments.
Aufgrund der hohen optischen Anforderungen werden ausschließlich Holzfurniere sehr hoher bzw. von höchster Qualität verwendet, was dementsprechend mit einem hohen Ausschussanteil und hohen Kosten je Furnierflächeneinheit verbunden ist. Aus Kostengründen weicht man daher bei Fahrzeugen unterhalb des Premiumsegments häufig auf Dekorelemente aus, die mit ansprechend gestalteten Folien überzogen sind. Der Unterschied gegenüber Dekorelementen, die aus ”Echtmaterial” hergestellt sind, zeigt sich jedoch in der Regel mit bloßem Auge an der nicht vorhandenen dreidimensionalen Strukturierung bzw. Maserung.by virtue of The high optical requirements are exclusively wood veneers very high or highest quality used accordingly with a high reject rate and high cost per veneer surface unit connected is. For cost reasons Therefore, you often give up on vehicles below the premium segment Decorative elements covered with attractively designed foils are. The difference compared to decorative elements, which are made of "real material", However, usually shows with the naked eye on the nonexistent three-dimensional structuring or grain.
Aufgabe der Erfindung ist es, ein Verfahren anzugeben, mit dem sich hochwertig anmutende Dekorelemente vergleichsweise kostengünstig herstellen lassen.task The invention is to provide a method with which high quality make seemingly decorative elements comparatively inexpensive.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Ausgangspunkt der Erfindung ist ein Verfahren zur Herstellung eines Dekorelements, insbesondere für Fahrgasträume von Fahrzeugen, bei dem zunächst ein Vorformling bereitgestellt wird, der bereits in etwa die Form des herzustellenden Dekorelements aufweist. Ferner wird ein Formwerkzeug bereitgestellt, das eine profilierte bzw. strukturierte Oberfläche aufweist, entsprechend einem ”Negativ” einer Oberfläche des herzustellenden Dekorelements. Der Vorformling wird dann in das Formwerkzeug eingebracht, so dass eine erste Seite des Vorformlings der profilierten bzw. strukturierten Oberfläche des Formwerkzeugs zugewandt ist. Anschließend wird der Vorformling mit seiner ersten Seite gegen die profilierte bzw. strukturierte Oberfläche des Formwerkzeugs gepresst, was zur Folge hat, dass sich die Profilierung bzw. die Struktur des Formwerkzeugs in die erste Seite des Vorformlings eindrückt bzw. einpresst.starting point the invention is a method for producing a decorative element, especially for passenger compartments of vehicles, at first a preform is provided which is already approximately the shape having the decorative element to be produced. Further, a mold provided that has a profiled surface, according to a "negative" one surface of the decorative element to be produced. The preform is then placed in introduced the mold, so that a first side of the preform the profiled or structured surface of the mold facing is. Subsequently the preform is profiled with its first side against the or structured surface pressed the mold, which has the consequence that the profiling or the structure of the mold in the first side of the preform push in or einpresst.
Als Material für den Vorformling kann beispielsweise ein kostengünstiges Holzfurnier verwendet werden, das eine im Wesentlichen ebene Oberfläche aufweist. Je nach Gestaltung der Profilierung bzw. Strukturierung des Formwerkzeugs kann eine nahezu beliebige Profilierung bzw. Strukturierung, wie etwa eine bestimmte Holzmaserung in den Vorformling eingeprägt werden.When Material for For example, the preform may use a low-cost wood veneer be, which has a substantially flat surface. Depending on the design the profiling or structuring of the mold can be an almost any profiling or structuring, such as a particular Wood grain can be embossed in the preform.
Nach dem ”Prägen” der durch die erste Seite des Vorformlings gebildeten Sichtseite des Dekorelements, kann diese z. B. durch Beizen bzw. Lackieren oder Beschichten bzw. Einfärben ”nachbehandelt” werden.To the "embossing" of the the first side of the preform formed visible side of the decorative element, can this z. B. by pickling or painting or coating or Dyeing be "post-treated".
Nach einer Weiterbildung der Erfindung wird eine der ersten Seite abgewandte zweite Seite des Vorformlings mit einem Kunststoffmaterial, insbesondere mit einem Thermo- oder Duroplastmaterial, einem ABS-Kunststoff oder mit Polycarbonat hinterspritzt.To a development of the invention is facing away from the first page second side of the preform with a plastic material, in particular with a thermo or thermoset material, an ABS plastic or back-injected with polycarbonate.
Das Einprägen der Profilierung bzw. Strukturierung in die erste Seite des Vorformlings und das Hinterspritzen des Vorformlings kann in ein und demselben Arbeitsschritt in einem Spritzgusswerkzeug erfolgen. Eine Innenseite des Spritzgusswerkzeugs ist hierzu mit dem ”Negativ” der in den Vorformling einzuprägenden Profilierung bzw. Strukturierung versehen. Nach dem Einbringen des Vorformlings in das Spritzgusswerkzeug wird dieses geschlossen. Anschließend wird das Kunststoffmaterial injiziert. Durch den Einspritzdruck bzw. durch den Werkzeuginnendruck, der vorzugsweise größer als 5 bar ist, wird der Vorformling mit seiner ersten Seite gegen die mit der Strukturierung bzw. Profilierung versehene Werkzeugoberfläche gepresst. Der Einspritzdruck bewirkt somit das Einprägen der Strukturierung bzw. Profilierung in die erste Seite des Vorformlings.The inculcate the profiling or structuring into the first side of the preform and the back molding of the preform can be in one and the same Work step done in an injection mold. An inside of the injection molding tool is for this purpose with the "negative" of einzaufrägenden in the preform profiling or structuring provided. After the introduction of the preform in the injection mold this is closed. Subsequently, will injected the plastic material. By the injection pressure or by the cavity pressure, which is preferably greater than 5 bar, the preform is with its first side against the the structuring or profiling provided tool surface pressed. The injection pressure thus causes the impressing of the structuring or profiling in the first page of the preform.
Mit diesem Verfahren ist es möglich, hochwertig anmutende Oberflächen kostengünstig herzustellen. Mit derselben Technologie kann auch eine Folie entsprechend geprägt werden. Ausdrücklich sei darauf hingewiesen, dass es sich bei dem Vorformling wahlweise auch um eine Folie oder ein ähnliches dünnschichtiges Material wie z. B. Aluminium- oder andere Metallfolien handeln kann.With this method it is possible high-quality surfaces economical manufacture. With the same technology can also be a film accordingly embossed become. Expressly It should be noted that the preform is optional also a film or a similar thin-layered Material such. B. aluminum or other metal foils can act.
Wie bereits erwähnt, kann vorgesehen sein, dass die der ersten Seite abgewandte zweite Seite des Vorformlings mit einem Kunststoffmaterial hinterspritzt wird. Zur Erzielung einer hohen Steifigkeit kann ein faserverstärktes, insbesondere ein durch Glasfaser oder Karbonfaser verstärktes Kunststoffmaterial verwendet werden.As already mentioned, can be provided that the first side facing away from the second Side of the preform with a plastic material behind injected becomes. To achieve a high rigidity, a fiber-reinforced, in particular a reinforced by glass fiber or carbon fiber plastic material used become.
Auf der zweiten Seite des Vorformlings kann ferner ein Halte- bzw. Verbindungselement angespritzt werden, an dem bzw. mittels dem das Dekorelement im Fahrzeug befestigt werden kann. Bei dem Halte- bzw. Verbindungselement kann es sich beispielsweise um ein armartiges Element, ein zapfenartiges Element, ein klammerartiges Element o. ä. handeln.On the second side of the preform, a holding or connecting element can also be injection molded, on or by means of which the decors can be fastened in the vehicle. The holding or connecting element may be, for example, an arm-like element, a pin-like element, a clip-like element or the like.
Die profilierte bzw. strukturierte Oberfläche des Formwerkzeugs kann beispielsweise aus Nickel oder einem nickelhaltigen Material hergestellt werden. Mit Oberflächen aus Nickel bzw. aus nickelhaltigem Material lassen sich selbst sehr fein profilierte bzw. strukturierte Oberflächen mit sehr hoher Qualität nachbilden.The profiled or structured surface of the mold can for example, made of nickel or a nickel-containing material become. With surfaces made of nickel or nickel-containing material can be very self reproduce finely profiled or structured surfaces with very high quality.
Die profilierte bzw. strukturierte Oberfläche des Formwerkzeugs kann durch eine Seite eines austauschbar in das Formwerkzeug eingesetzten Elements, z. B. eines Nickelblechs gebildet sein. Durch Austauschen des die Profilierung bzw. Strukturierung aufweisenden Elements können mit ein und demselben Formwerkzeug verschiedenartige Profilierungen bzw. Strukturierungen nachgebildet werden.The profiled or structured surface of the mold can through a side of an element inserted interchangeably into the mold, z. B. a nickel sheet may be formed. By replacing the the Profiling or structuring element can with one and the same mold different profiles or structures are modeled.
