Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Herstellen eines Formteils mit einer Basisschicht und einer Deckschicht, bei dem die Basisschicht und die Deckschicht in einem einzigen Arbeitsschritt unter Einwirkung von Druck und Wärme verpreßt werden.The present invention relates to a method for Manufacture of a molded part with a base layer and one Top layer, in which the base layer and the top layer in a single step under pressure and Heat to be pressed.
Ein gattungsgemäßes Verfahren ist aus der EP 0 325 690 B1 be kannt. Bei dem dort dargestellten Verfahren ist es möglich, eine Basislage und eine Deckfurnierlage in einem einzigen Preßstanzvorgang zu einem Werkstück mit einer ansprechenden Oberfläche zu formen. Bevorzugt besteht die Basislage zumin dest teilweise aus Holz oder aus einem aus mehreren Einzella gen geschichteten Basisfurnier. Die Verbindung zwischen Basis lage und Deckfurnierlage wird bei dem bekannten Verfahren durch Kunstharzkleber hergestellt. Mit dem bekannten Verfahren erhält man Furnierwerkstücke von guter Oberflächenbeschaffen heit und mit einer hohen Verwindungssteifigkeit.A generic method is known from EP 0 325 690 B1 knows. With the method shown there, it is possible to one base layer and one face veneer layer in one Press stamping process to a workpiece with an appealing Shape surface. The base layer preferably consists of at least partly from wood or from one of several single cells layered base veneer. The connection between base Layer and face veneer layer is in the known method made by synthetic resin adhesive. With the known method you get veneer workpieces with good surface finishes unit and with high torsional rigidity.
Nachteilig an dem bekannten Verfahren ist jedoch, daß der Auf bau des Schichtverbundes der jeweils erwünschten Deckschicht und dem vorgesehenen Einsatzbereich angepaßt werden muß. Wei terhin ist es erforderlich, Befestigungselemente, mit denen das Formteil zum Beispiel zur Innenverkleidung eines Fahrzeugs angebracht wird, nachträglich an dem verpreßten Formteil anzu bringen.A disadvantage of the known method, however, is that the up Construction of the layer composite of the desired top layer and must be adapted to the intended area of application. Wei terhin it is necessary to fasteners with which the molded part, for example, for the interior lining of a vehicle is attached to retrofitted to the molded part bring.
Es ist demnach die Aufgabe der vorliegenden Erfindung ein Ver fahren zur Verfügung zu stellen, bei dem weitgehend unabhängig von der Oberflächenbeschaffenheit des zu fertigenden Formtei les eine einheitliche Basisschicht verwendet werden kann, so daß die Herstellung unterschiedlicher Formteile in derselben Weise erfolgen kann. Gleichzeitig soll das Verfahren jedoch hinreichend flexibel sein, daß zum Zwecke der Optimierung, beispielsweise der Verbindung zwischen Deckschicht und Basis schicht, zusätzliche Maßnahmen getroffen werden können. Inso fern liegt der gestellten Aufgabe die Rationalisierung des Herstellungsverfahrens zugrunde. Zusätzlich soll ein nachträg liches Anbringen von Befestigungsvorrichtungen an dem Formteil überflüssig werden.It is therefore an object of the present invention to Ver drive to make available largely independent on the surface condition of the molded part to be manufactured les a uniform base layer can be used, so that the production of different molded parts in the same Way can be done. At the same time, however, the process should be sufficiently flexible that for the purpose of optimization, for example the connection between the cover layer and the base layer, additional measures can be taken. Inso the task of rationalizing the Manufacturing process based. In addition, a subsequent Lich attaching fasteners to the molding become superfluous.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß zum Bilden der Basisschicht eine oder mehrere SMC (Sheet Molding Compound)-Matte(n) oder ein durch einen Angußkanal in das Werkzeug eingespritztes BMC-Material verwendet wird/werden. Bei den verwendeten SMC-Matten handelt es sich um flächige Gebilde, welche aus ungesättigten Polyesterharzen mit Glasfi lamenten bestehen. Vorzugsweise sind LP (Low Profile)-Hochpo lymer-Komponenten in stark schwundkompensierter Einstellung als Bestandteil der SMC-Matte vorgesehen, weitere Bestandteile sind Additive, wie Trennmittel und Lagerstabilisatoren sowie mineralische Füllstoffe in beliebiger Farbeinstellung. BMC steht für "bulk molding compound". Ein hieraus bestehendes Material kann im quasi flüssigen Zustand in das Werkzeug ein gespritzt werden.According to the invention, this object is achieved in that Form the base layer one or more SMC (Sheet Molding Compound) mat (s) or one through a sprue into the Tool-injected BMC material is used. The SMC mats used are flat Formations made of unsaturated polyester resins with glass fi wills exist. LP (Low Profile) high-speed are preferred lymer components in a highly shrink-compensated setting intended as part of the SMC mat, other components are additives such as release agents and storage stabilizers as well mineral fillers in any color setting. BMC stands for "bulk molding compound". An existing one Material can enter the tool in a quasi-liquid state be injected.
Bei dem erfindungsgemäßen Verfahren sollten Wärmezufuhr und Druck bis zum vollständigen Aushärten der aushärtbaren Kompo nenten aufrechterhalten werden.In the method according to the invention, heat and Print until the hardenable compo is completely hardened be maintained.
Das Verpressen erfolgt vorzugsweise bei einer Temperatur zwi schen 120°C und 160°C, besonders bevorzugt ist der Temperatur bereich zwischen 140°C und 160°C.The pressing is preferably carried out at a temperature between 120 ° C and 160 ° C, the temperature is particularly preferred range between 140 ° C and 160 ° C.
Je nach den Rahmenbedingungen, wie zum Beispiel der Dicke des Formteils und der verwendeten Temperatur sind verschiedene Zeiträume zum Aushärten der aushärtbaren Materialien erforder lich. Der Zeitraum zum Aushärten variiert daher zwischen ca. 30 Sekunden und 5 Minuten, er wird bevorzugt aber zwischen 2 und 3 Minuten liegen.Depending on the general conditions, such as the thickness of the The molded part and the temperature used are different Time periods required for the hardenable materials to harden Lich. The curing time therefore varies between approx. 30 seconds and 5 minutes, but is preferred between 2 and 3 minutes.
Als Deckschicht werden bevorzugt Furniere verwendet.Veneers are preferably used as the top layer.
Diese haben vorteilhafterweise eine Dicke zwischen 0,1 Milli metern und 0,9 Millimetern, häufig wird die Dicke zwischen 0,4 Millimetern und 0,6 Millimetern liegen.These advantageously have a thickness between 0.1 milli meters and 0.9 millimeters, the thickness is often between 0.4 Millimeters and 0.6 millimeters.
Es werden bevorzugt Dekorfurniere, zum Beispiel Echtholzfur niere, verwendet.Decorative veneers, for example real wood, are preferred kidney, used.
Es kann weiterhin vorgesehen sein, daß als zusätzliche Zwischenschicht ein Vlies oder Blindfurnier in den Schichtver bund eingebracht wird. Hierdurch verbessert sich die Eigen steifigkeit, wodurch sich eine bessere Handhabung der Dekor furniere, insbesondere wenn es sich um Echtholzfurniere han delt, ergibt.It can also be provided that as an additional Interlayer a fleece or blind veneer in the layer ver is brought in. This improves the own stiffness, resulting in better handling of the decor veneers, especially when it comes to real wood veneers delt, results.
Je nach Beschaffenheit des Formteils, insbesondere des verwen deten Furniers, kann es unter Umständen günstig sein, einen Klebefilm zwischen Deckschicht und Zwischenschicht anzuordnen.Depending on the nature of the molded part, especially the use veneer, it may be beneficial to buy one Arrange adhesive film between the top layer and the intermediate layer.
Dieser ist dann bevorzugt von duroplastischer Art auf Basis von Natronkraft- oder Recyclingpapieren, die mit einem Harn stoff-Melamin-Harz-Gemisch imprägniert sind.This is then preferably based on a thermosetting type of sodium kraft or recycled paper containing a urine impregnated fabric-melamine-resin mixture.
Auch kann das Einbringen von duroplastischen Harzen, wie Phe nolharzen oder ähnlichem besondere Vorteile mit sich bringen.The introduction of thermosetting resins such as Phe nol resins or the like bring special advantages.
Ein besonderer Vorteil des erfindungsgemäßen Verfahrens be steht darin, daß Befestigungselemente, zum Beispiel auf der Rückseite oder an den Seitenkanten des Formteils sogleich bei dem Preßvorgang anformbar sind bzw. eingebettet werden können.A particular advantage of the method according to the invention is that fasteners, for example on the Back or on the side edges of the molded part immediately the molding process can be molded or embedded.
Die Herstellung der Formteile wird vorteilhafterweise in ge eigneten Pressen bzw. Werkzeugen stattfinden.The production of the molded parts is advantageously in ge own presses or tools.
Als Deckschicht können natürliche und/oder künstliche Werk stoffe und/oder Kombinationen aus den genannten Materialarten verwendet werden.Natural and / or artificial work can be used as a top layer fabrics and / or combinations of the types of materials mentioned be used.
Weiterhin ist es möglich, verschiedene Dekorationsmaterialien, wie Stoff, Textil, Kunstleder, Leder, Kunststoff, Papier, pa pierähnliche Stoffe, Metalle und/oder Kombinationen aus diesen Materialien zu verwenden.It is also possible to use different decoration materials, such as fabric, textile, synthetic leather, leather, plastic, paper, pa pier-like substances, metals and / or combinations of these To use materials.
Besonders vorteilhaft erweist sich das Verfahren, wenn die Deckschicht eine der Sichtfläche abgewandte Beschichtung auf weist, die ein Einreißen der Deckschicht beim Verpreßvorgang verhindert.The method proves to be particularly advantageous if the Top layer a coating facing away from the visible surface has a tearing of the cover layer during the pressing process prevented.
Weiterhin hat das Verfahren besondere Vorteile, wenn die Deck schicht und die Basisschicht beim Verpreßvorgang im Kanten- und Randbereich mittels Tauchkanten konturgenau von etwaigen Überständen befreit werden.Furthermore, the method has special advantages when the deck layer and the base layer during the pressing process in the edge and edge area by means of plunge edges of any contours Supernatants are released.
Es können auch verschiedene Deckschichtmaterialien nebenein anderliegend angeordnet werden.Different cover layer materials can also be used in parallel be arranged elsewhere.
Die überraschenden Vorteile des erfindungsgemäßen Verfahrens bestehen vor allem darin, daß für sehr verschiedene Oberflä chen ein einheitliches Vorgehen möglich ist, vor allem bedingt durch die besonders günstigen Eigenschaften der erfindungsge mäß vorgesehenen SMC-Matte. Es ist somit ohne die ansonsten häufig erforderlichen Anstrengungen möglich, eine Anlage von der Produktion von Formteilen der einen Oberfläche, wie zum Beispiel Echtholzfurnier, auf Formteile mit einer anderen Oberfläche, wie zum Beispiel Stoff oder dergleichen, umzustel len. Gelegentlich auftretende besondere Anforderungen aufgrund besonders schwierig zu verarbeitender Deckschichten können trotz der Einheitlichkeit des Verfahrens durch ein verbliebe nes Maß an Flexibilität ausgeglichen werden, wie beispielswei se durch das Einbringen von Klebefilmen oder Vliesen sowie duroplastischen Harzen. Das Formteil verbleibt bis zum voll ständigen Aushärten in seiner Form, so daß eine unproblemati sche Entnahme des fertigen Werkstücks erfolgen kann. Das Preß werkzeug steht dann sogleich für den nächsten Produktionsvor gang zur Verfügung. Durch die günstigen Fließeigenschaften der geschmolzenen Materialien ist es möglich, Befestigungsvorrich tungen direkt beim Preßvorgang anzuformen bzw. einzubetten. Die Verfahrensparameter, wie Zeit, Temperatur und Druck beim Preßvorgang können so angepaßt werden, daß das geschmolzene Material auch in kleine Formnestbereiche fließen kann, wodurch das Anformen von Befestigungsvorrichtungen möglich wird. Be sondere Vorteile bei der Verwendung von SMC-Matten ergeben sich weiterhin aus ihrer guten Lagerfähigkeit. Auf Rollen ge wickelt können vorbereitete SMC-Matten bis zu einem halben Jahr gelagert werden. Weiterhin zeichnet sich das Verfahren dadurch aus, daß mit kurzen Taktzeiten Formteile von höchster Festigkeit hergestellt werden können, weil die jeweils vorge gebenen Faserverstärkungsstrukturen beim Preßvorgang weitge hend erhalten bleiben.The surprising advantages of the method according to the invention consist mainly in the fact that for very different surfaces a uniform approach is possible, especially to a limited extent due to the particularly favorable properties of the fiction according to the intended SMC mat. It is therefore without the otherwise Efforts often required to create a facility the production of molded parts of one surface, such as Example real wood veneer, on molded parts with another To change surface, such as fabric or the like len. Occasional special requirements due to cover layers that are particularly difficult to process despite the uniformity of the procedure by a a degree of flexibility, such as se by inserting adhesive films or nonwovens as well thermosetting resins. The molding remains until full constant curing in its form, so that an unproblematic the finished workpiece can be removed. The press tool is then immediately available for the next production available. Due to the favorable flow properties of the molten materials it is possible to fixation device to form or embed the lines directly during the pressing process. The process parameters, such as time, temperature and pressure at Pressing process can be adjusted so that the melted Material can flow into small mold cavity areas, causing the molding of fastening devices is possible. Be result in special advantages when using SMC mats continue from their good storability. On wheels Prepared SMC mats can wrap up to half Year. Furthermore, the process stands out characterized in that with short cycle times molded parts of the highest Strength can be produced because the respective pre Given fiber reinforcement structures during the pressing process remain intact.
Anhand der Zeichnungen soll das erfindungsgemäße Verfahren im folgenden beispielhaft erläutert werden.Using the drawings, the inventive method in following are exemplified.
Fig. 1 zeigt ein Preßstanzwerkzeug in einer Schnitt ansicht senkrecht zu seiner Hauptebene in ge öffnetem Zustand mit eingelegter SMC-Matte und Deckschicht vor dem Preßvorgang. Fig. 1 shows a press punch in a sectional view perpendicular to its main plane in the open state with inserted SMC mat and top layer before the pressing process.
Fig. 2 zeigt das Preßstanzwerkzeug aus Fig. 1 während des Preßvorgangs. FIG. 2 shows the press punching tool from FIG. 1 during the pressing process.
Fig. 1 zeigt ein Preßstanzwerkzeug 2 mit einem beweglichen Stanzwerkzeug 4 und einem Gegenwerkzeug 6. Das Stanzwerkzeug 4 weist eine Stanzfläche 8 auf, das Gegenwerkzeug eine Gegenflä che 10. Das Stanzwerkzeug 4 und das Gegenwerkzeug 6 liegen einander mit Stanzfläche 8 und Gegenfläche 10 gegenüber. Zwi schen Stanzfläche 8 und Gegenfläche 10 ist in dem in Fig. 1 dargestellten geöffneten Zustand des Preßstanzwerkzeugs 2 ein Zwischenraum 12 dargestellt, welcher das Einlegen einer SMC- Matte 18 sowie einer Deckschicht 20 ermöglicht. Das Gegenwerk zeug 6 weist an seiner Gegenfläche 10 Ausnehmungen 14, 16 auf, auf deren Bedeutung im Zusammenhang mit Fig. 2 eingegangen wird. Fig. 1 shows a pressing and punching tool 2 with a movable die 4 and a counter die 6. The punch 4 has a punch surface 8 , the counter tool surface 10 . The punching tool 4 and the counter tool 6 lie opposite one another with the punching surface 8 and the counter surface 10 . Between the punching surface 8 and the counter surface 10 , an intermediate space 12 is shown in the open state of the press punch 2 shown in FIG. 1, which allows the insertion of an SMC mat 18 and a cover layer 20 . The counterpart tool 6 has on its counter surface 10 recesses 14 , 16 , the importance of which is discussed in connection with FIG .
In Fig. 2 ist dasselbe Preßstanzwerkzeug während des Preßvor gangs dargestellt. In diesem Zustand sind SMC-Matte 18 und Deckschicht 20 durch das Pressen der Stanzfläche 8 des Stanz werkzeugs 4 gegen die Gegenfläche 10 des Gegenwerkzeugs 6 zu einem Formteil 22 verpreßt. Das während des Preßvorgangs ver flüssigte Material ist auch in die Ausnehmungen 14, 16 der Gegenfläche im Gegenwerkzeug eingedrungen, so daß während des Preßvorgangs sogleich Befestigungsvorrichtungen 24, 26, in diesem Fall an der Rückseite des Formteils, angeformt werden. In Fig. 2 the same press punch tool is shown during the Preßvor gear. In this state, SMC mat 18 and cover layer 20 are pressed by pressing the punching surface 8 of the punching tool 4 against the counter surface 10 of the counter tool 6 to form a molded part 22 . The ver liquid material during the pressing process has also penetrated into the recesses 14 , 16 of the counter surface in the counter tool, so that fastening devices 24 , 26 , in this case on the back of the molded part, are formed during the pressing process.
Im Falle der Verwendung von BMC-Material ist das Preßstanz werkzeug 2 mit einem Angußkanal ausgestattet, durch welchen des flüssige Material in das Werkzeug eingebracht wird. Ansonsten erweist sich das Verfahren unter Verwendung von BMC- Material als ebenso vorteilhaft wie bei der Verwendung von SMC-Matten, insbesondere im Hinblick auf die Variabilität der ansonsten eingesetzten Werkstoffe, der Handhabbarkeit des fer tig ausgehärteten Formteiles sowie der Möglichkeit, Befesti gungsvorrichtungen sogleich anzuformen.In the case of using BMC material, the press punch tool 2 is equipped with a sprue through which the liquid material is introduced into the tool. Otherwise, the method using BMC material proves to be just as advantageous as when using SMC mats, in particular with regard to the variability of the materials otherwise used, the manageability of the finished, hardened molded part and the possibility of immediately forming fastening devices.
