Description

Verfahren zur Herstellung eines bedruckten Kunststoffbauteils, Method for producing a printed plastic component,
Vorrichtung zur Durchführung des Verfahrens sowie nach dem Verfahren hergestelltes KunststoffbauteilApparatus for carrying out the method and produced by the method plastic component
Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines bedruckten Kunststoffbauteils, eine Vorrichtung zur Durchführung des Verfahrens sowie ein nach dem Verfahren hergestelltes Kunststoffbauteil.The present invention relates to a method for producing a printed plastic component, a device for carrying out the method and a plastic component produced by the method.
Aus dem Stand der Technik ist es bekannt, transparente Folien mittels gängiger Druckverfahren, wie Tamponprint, Siebdruck, Offsetdruck, Digitaldruck, etc. zu bedrucken, um Bauteile mit Dekor-Mustern und/oder Dekor-Symbolen, Schriftzügen etc. insbesondere mit Tiefenwirkung, d.h. mit einem dreidimensionalen Effekt herzustellen. Aus dem Stand der Technik ist es ferner bekannt, Bauteile mit einem transparenten Kunststoff, insbesondere mit Polycarbonat, PMMA oder vernetzenden Harzen wie Polyurethan, zu überspritzen, zu übergießen oder zu lackieren. All diese Verfahren haben jedoch den Nachteil, dass sie vergleichsweise aufwändig und zudem teuer sind.It is known from the prior art to print transparent films by means of conventional printing processes, such as pad printing, screen printing, offset printing, digital printing, etc., in order to produce components with decorative patterns and / or decorative symbols, letterings, etc., in particular with a depth effect, i. to produce with a three-dimensional effect. From the prior art, it is also known to overmold, over-coat or paint components with a transparent plastic, in particular with polycarbonate, PMMA or crosslinking resins such as polyurethane. However, all these methods have the disadvantage that they are relatively complex and also expensive.
Die genannten Verfahren werden auf planen Flächen angewandt. Anschließend wird die Folie in die gewünschte, dreidimensionale Struktur verformt und sodann hinterspritzt. Dabei tritt das Problem auf, dass die Positionsgenauigkeit des Druckes häufig nicht gewährleistet ist, und dass sich der Aufdruck durch den Umformprozeß verzerren kann.The above methods are applied to flat surfaces. Subsequently, the film is deformed into the desired, three-dimensional structure and then back-molded. The problem arises that the position accuracy of the pressure is often not guaranteed, and that the imprint can be distorted by the forming process.
Aus der DE 39 05 177 A1 ist ein Verfahren bekannt, bei dem eine bedruckte Kunststofffolie in einem Formwerkzeug einem Hochdruck von 20 bis 300 bar ausgesetzt wird. Durch dieses HPF-Verfahren, d. h. durch die Kaltverformung der Folie mittels Hochdruck, können die aus dem Stand der Technik bekannten Nachteile der mangelnden Positionsgenauigkeit oder der Verzerrung des Aufdruckes weitgehend vermieden werden, allerdings besteht bei dem HPF- Verfahren ein Nachteil darin, dass es aufgrund des Erfordernisses der Erzeugung von Preßluft teuer ist und dass keine größeren Verstreckungsverhältnisse realisierbar sind.From DE 39 05 177 A1 a method is known in which a printed plastic film is exposed in a mold to a high pressure of 20 to 300 bar. Through this HPF method, i. H. by cold working the film by high pressure, the drawbacks known from the prior art of the lack of positional accuracy or the distortion of the imprint can be largely avoided, however, there is a drawback in the HPF process that it is expensive due to the requirement of the production of compressed air is and that no larger draw ratios are feasible.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Verfahren bereitzustellen, das eine positionsgenaue Anordnung von Dekoren und/oder Symbolen und dergleichen ermöglicht und bei dem auch große Verstreckungsverhältnisse realisierbar sind. Weiterhin liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Verfahren bereitzustellen, mittels dessen bei Bedarf eine „Tiefenwirkung" erzeugt werden kann.The present invention is therefore based on the object to provide a method which allows a positionally accurate arrangement of decors and / or symbols and the like and in which also large draw ratios can be realized. Furthermore, the present invention has for its object to provide a method by means of which, if necessary, a "depth effect" can be generated.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 gelöst. Danach ist vorgesehen, dass das erfindungsgemäße Verfahren den Schritt des (a) Verformens einer wenigstens bereichsweise transparenten oder wenigstens bereichsweise transluzenten Kunststofffolie oder -platte, (b) das Bedrucken der in Schritt (a) verformten Kunststofffolie oder -platte und (c) das Hinterfüttern der in Schritt (b) bedruckten Kunststofffolie oder -platte umfaßt. Erfindungsgemäß ist somit vorgesehen, dass die Folie oder Platte zunächst verformt wird, dass die verformte Folie oder Platte bedruckt wird und das die bedruckte und verformte Folie oder Platte sodann hinterfüttert wird. Auf diese Weise lassen sich Bauteile mit hoher Verstreckung, positionsgenauen Dekoren und dergleichen und mit einer Tiefenwirkung herstellen. Selbstverständlich ist das erfindungsgemäße Verfahren auch einsetzbar, wenn eine solche Tiefenwirkung nicht erwünscht ist. Dies läßt sich beispielsweise dadurch realisieren, dass eine vergleichsweise dünne Folie beispielsweise von weniger als 375 μm eingesetzt wird. Bei diesen Folien tritt der Effekt der Tiefenwirkung nicht oder nur im geringem Umfang auf. Der Vorteil der hohen Positionsgenauigkeit bleibt jedoch erhalten.This object is achieved by a method having the features of claim 1. Thereafter, it is provided that the method according to the invention comprises the step of (a) deforming a plastic film or sheet which is at least partially transparent or at least partially translucent, (b) printing the plastic film or sheet deformed in step (a) and (c) backing it the printed in step (b) printed plastic film or plate. The invention thus provides that the film or plate is first deformed, that the deformed film or plate is printed and then the printed and deformed film or plate is then backfilled. In this way, components with high draft, positionally accurate decors and the like and with a depth effect can be produced. Of course, the inventive method also usable, if such a depth effect is not desired. This can be achieved, for example, by using a comparatively thin film of, for example, less than 375 μm. In these films, the effect of the depth effect does not occur or only to a small extent. However, the advantage of high positional accuracy remains.
Die folgenden Ausführungen beziehen sich auf eine „Kunststofffolie" gelten sinngemäß jedoch auch für eine „Kunststoffplatte", deren Verwendung im Rahmen des erfindungsgemäßen Verfahrens ebenfalls von der Erfindung umfaßt ist.The following statements relate to a "plastic film" apply mutatis mutandis, however, also for a "plastic plate", the use of which is also included within the scope of the inventive method of the invention.
In einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass das Bedrucken der verformten Kunststofffolie durch Tamponprint erfolgt.In a preferred embodiment of the invention, it is provided that the printing of the deformed plastic film takes place by tampon printing.
In einer weiteren bevorzugten Ausgestaltung der Erfindung ist alternativ oder zusätzlich vorgesehen, dass das Bedrucken der verformten Kunststofffolie durch Heißprägen erfolgt.In a further preferred embodiment of the invention is alternatively or additionally provided that the printing of the deformed plastic film is carried out by hot stamping.
Alternativ oder zusätzlich ist es möglich, das Bedrucken der verformten Kunststofffolie durch Siebdruck, Offsetdruck, Digitaldruck, Laserdruck, Lackieren, Stempeln und dergleichen durchzuführen. An dieser Stelle sei darauf hingewiesen, dass das Wort „Bedrucken" im Rahmen der vorliegenden Erfindung nicht auf ein „Druckverfahren" beschränkt ist, sondern allgemein das Aufbringen des gewünschten Dekors, Symbols, Textes und dergleichen auf die Folie umfaßt.Alternatively or additionally, it is possible to perform the printing of the deformed plastic film by screen printing, offset printing, digital printing, laser printing, painting, stamping and the like. It should be noted that the term "printing" in the context of the present invention is not limited to a "printing process", but generally includes the application of the desired decoration, symbol, text and the like on the film.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das Bedrucken der verformten Kunststofffolie ein- oder zweiseitig erfolgt. Es ist dabei beispielsweise möglich, dass nur die Rückseite der Kunststofffolie bedruckt wird. Dies hat den Vorteil, dass das Dekor, das Symbol, der Schriftzug und dergleichen durch die Folie vor Abrieb und Zerstörung geschützt ist.In a further embodiment of the invention, it is provided that the printing of the deformed plastic film takes place on one or two sides. It is possible, for example, that only the back of the plastic film is printed. This has the advantage that the decor, the symbol, the lettering and the like is protected by the film from abrasion and destruction.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass das Bedrucken der verformten Kunststofffolie zweiseitig erfolgt und dass das Bedrucken der beiden Seiten der Folie mit derselben oder mit unterschiedlichen Techniken erfolgt. Es ist somit möglich, zwei unterschiedliche Verfahren oder auch dasselbe Verfahren zum Bedrucken der beiden Seiten der Folie anzuwenden. Denkbar ist es, die Folie von beiden Seiten zu bedrucken und somit Designs auf zwei Ebenen, d. h. auf der Folienvorderseite und auf der Folienrückseite mit einer transparenten oder transluzenten Zwischenschicht zu erzeugen.In a further embodiment of the invention, it is provided that the printing of the deformed plastic film is done on two sides and that the printing of the two Pages of the film is done with the same or with different techniques. It is thus possible to use two different methods or the same method for printing the two sides of the film. It is conceivable to print the film from both sides and thus to produce designs on two levels, ie on the front of the film and on the back of the film with a transparent or translucent intermediate layer.
Denkbar ist es beispielsweise, auf der Folienrückseite durch Heißprägen ein Dekor aufzubringen auf der Folienvorderseite durch ein anderes Verfahren, beispielsweise durch Digital- oder Laserdruck ein anderes Symbol aufzubringen. In Abhängigkeit der Foliendicke kann durch das zweiseitige Bedrucken der Folie eine dreidimensionale Anmutung des Dekors, des Symbols, des Schriftzuges und dergleichen noch verstärkt werden.It is conceivable, for example, to apply a decor on the back of the film by hot stamping on the front of the film by another method, for example by digital or laser printing to apply another symbol. Depending on the film thickness, a three-dimensional appearance of the decoration, the symbol, the lettering and the like can be enhanced by the two-sided printing of the film.
Wie bereits oben ausgeführt, kann das Bedrucken, beispielsweise das Heißprägen in einem ebenen oder auch bis zu gewissen Grenzen in einem dreidimensional verformten Bereich stattfinden. Handelt es sich um das Verfahren des Heißprägens, wird im letzteren Fall der Heißprägestempel entsprechend angepaßt.As already stated above, the printing, for example hot embossing, can take place in a plane or even to a certain extent in a three-dimensionally deformed region. If it is the process of hot embossing, the hot stamping die is adapted accordingly in the latter case.
Die Verformung der Folie kann beispielsweise durch Thermoformen erfolgen. Somit wird zunächst eine durch Thermoformen umgeformte Folie erstellt und diese bedruckt und anschließend hinterfüttert, um das gewünschte Dekorbauteil zu erhalten.The deformation of the film can be done for example by thermoforming. Thus, a formed by thermoforming foil is first created and printed this and then backfilled to obtain the desired decorative component.
Unter Hinterfüttern können im Rahmen der vorliegenden Erfindung alle formgebenden Fertigungsverfahren, wie z. B. Spritzgießen, Fließ- und Formpressen, Thermoplastschaumguß, Spritzprägen, Faserspritzen (LFI), Laminieren usw. verstanden werden.In the context of the present invention, under-lining may include all shaping production processes, such as, for example, As injection molding, flow and compression molding, thermoplastic foam, injection compression molding, fiber spraying (LFI), laminating, etc. are understood.

Beispielsweise kann die Folie auch durch zwei Formhälften geformt werden. In Betracht kommen z. B. auch Hydro- bzw. Explosionsformen.The thermoforming can be done by vacuum or overpressure. In principle, other methods than thermoforming are conceivable. For example, the film can also be formed by two mold halves. In consideration come z. B. also hydro or explosive forms.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Folie zumindest in dem bedruckten Bereich eine Dicke von > 375 μm aufweist. Der Tiefenwirkungseffekt, d. h. die dreidimensionale Anmutung des Dekors tritt insbesondere ab einer Materialdicke von ca. 375 μm auf. Wie oben ausgeführt, kann der dreidimensionale Effekt durch das beidseitige Bedrucken der. Folie verstärkt werden.In a further embodiment of the invention, it is provided that the film has a thickness of> 375 μm, at least in the printed area. The depth effect effect, d. H. The three-dimensional appearance of the decoration occurs in particular from a material thickness of about 375 microns. As stated above, the three-dimensional effect of the two-sided printing of the. Reinforced film.
Besonders bevorzugt ist es, wenn die Folie zumindest in dem bedruckten Bereich eine Dicke von > 1 mm, vorzugsweise eine Dicke im Bereich zwischen 1 mm und 2 mm aufweist. Das erfindungsgemäße Verfahren kann selbstverständlich auch auf Folien Anwendung finden kann, die eine Dicke von > 2mm aufweisen.It is particularly preferred if the film has a thickness of> 1 mm, preferably a thickness in the range between 1 mm and 2 mm, at least in the printed area. Of course, the method according to the invention can also be applied to films having a thickness of> 2 mm.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Folie beispielsweise aus Polycarbonat, PMMA, PET, Polyethylen, Polyamid, Polystyrol, formbarem Polyurethan, formbarem Epoxidharz, formbarem Polyester besteht oder eines oder eine Kombination dieser Materialien aufweist.In a further embodiment of the invention, it is provided that the film consists for example of polycarbonate, PMMA, PET, polyethylene, polyamide, polystyrene, moldable polyurethane, moldable epoxy resin, moldable polyester or one or a combination of these materials.

When the printing of the plastic film is completed, the stamp is pulled back to its original position.
Die Erfindung betrifft des weiteren ein Kunststoffbauteil, insbesondere ein Dekorbauteil, das nach dem erfindungsgemäßen Verfahren hergestellt ist.The invention further relates to a plastic component, in particular a decorative component, which is produced by the process according to the invention.
Weitere Einzelheiten und Vorteile der vorliegenden Erfindung werden anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Die einzige Figur zeigt den Prinzipaufbau eines erfindungsgemäß hergestellten Dekorbauteils.Further details and advantages of the present invention will be explained in more detail with reference to an embodiment shown in the drawing. The single FIGURE shows the basic structure of a decorative component according to the invention.
Mit dem Bezugszeichen 10 ist eine transparente oder transluzente Kunststofffolie gekennzeichnet. Diese Kunststofffolie ist durch Thermoformen dreidimensional in ihre endgültige Form verformt.Reference numeral 10 denotes a transparent or translucent plastic film. This plastic film is thermoformed three-dimensionally into its final shape.
Die obere Seite der Kunststofffolie 10 bildet die Außenseite des Dekorbauteils.The upper side of the plastic film 10 forms the outside of the decorative component.
Mit dem Bezugszeichen 20 ist ein Symbol gekennzeichnet, das durch Heißprägen auf die Rückseite der Kunststofffolie oder -Platte 10 aufgebracht ist, nachdem diese dreidimensional durch Thermoformen verformt wurde. Optional kann das Symbol alternativ oder zusätzlich auch auf der Vorderseite der Kunststofffolie oder Platte angeordnet sein, wie dies durch das Bezugszeichen 30 angedeutet ist. Die Kunststofffolie oder -Platte 10 wird nach dem Bedrucken hinterfüttert.Denoted by the reference numeral 20 is an icon which is hot-stamped on the reverse side of the plastic film or plate 10 after it has been three-dimensionally deformed by thermoforming. Optionally, the symbol may alternatively or additionally also be arranged on the front side of the plastic film or plate, as indicated by reference numeral 30. The plastic film or plate 10 is backfilled after printing.
Die Kunststoffmasse (oder dergleichen) ist durch das Bezugszeichen 40 gekennzeichnet.The plastic mass (or the like) is indicated by the reference numeral 40.
Die obere Darstellung kennzeichnet das erfindungsgemäße Dekorbauteil in einer dreidimensionalen Ansicht und die untere Darstellung in einer Seitenansicht.The upper illustration identifies the decorative component according to the invention in a three-dimensional view and the lower representation in a side view.
Grundsätzlich ist es möglich, die Kunststofffolie ein- oder zweiseitig durch Heißprägen oder auch durch ein anderes geeignetes Verfahren zu bedrucken, d. h. mit einem Symbol, mit einem Logo, mit einem Schriftzug, mit einer farblichen Fläche etc. zu versehen.In principle, it is possible to print the plastic film on one or two sides by hot stamping or by another suitable method, d. H. with a symbol, a logo, a lettering, a colored area, etc.
Wesentlich ist, dass dieser Vorgang nach dem Umformen der Folie/Platte zum Insert erfolgt. Nach dem Bedrucken erfolgt das Hinterfüttern des Inserts, wodurch ein dreidimensionales Bauteil mit Dekordruck und/oder Tiefeneffekt erhalten wird. Wie oben ausgeführt, ist es zum Erhalt des Tiefeneffektes vorteilhaft, wenn eine Folie einer Dicke von > 375μm, vorzugsweise von 1 mm bis 2 mm eingesetzt wird. Der dreidimensionale Tiefeneffekt kann verstärkt werden, wenn die Folie oder Platte 10 von beiden Seiten bedruckt wird, wie dies in der Figur angedeutet ist.It is essential that this process takes place after the forming of the film / plate to the insert. After printing, the insufflation of the insert takes place, whereby a three-dimensional component with decor pressure and / or depth effect is obtained. As stated above, it is advantageous to obtain the depth effect, if a film of a thickness of> 375μm, preferably from 1 mm to 2 mm is used. The three-dimensional depth effect can be enhanced if the film or plate 10 is printed from both sides, as indicated in the figure.
Ein wesentlicher Vorteil des erfindungsgemäßen Verfahrens ist die Positionsgenauigkeit des Druckes, der verzerrungsfreie Druck, die Kombinationsmöglichkeiten mit anderen Dekorationsverfahren sowie die vergleichsweise geringen Kosten und die Flexibilität des Verfahrens. Soll ein anderes Dekor ausgewählt werden, reicht es aus, einen neuen Stempel bzw. eine andere Heißprägefolie einzusetzen.A significant advantage of the method according to the invention is the position accuracy of the pressure, the distortion-free pressure, the possible combinations with other decoration methods and the relatively low cost and flexibility of the method. If another decor is to be selected, it is sufficient to use a new stamp or another hot stamping foil.
Ein Vorteil gegenüber dem HPF-Verfahren besteht insbesondere darin, dass das erfindungsgemäße Verfahren vergleichsweise günstig durchführbar ist und dass erfindungsgemäß auch größere Verstreckungsverhältnisse, wie sie beim Thermoformen möglich sind, realisierbar sind. An advantage over the HPF process is, in particular, that the process according to the invention can be carried out comparatively favorably and that, according to the invention, even larger draw ratios, such as are possible during thermoforming, can be realized.
