Abstract
Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Bauteils gemäß dem Oberbegriff von Patentanspruch 1.The invention relates to a method for producing a component according to the preamble of patent claim 1.
Ein Verfahren zum Herstellen eines Bauteils aus aus einem Kunststoff gebildeten Schaumpartikeln ist aus der
Ein solches Verfahren ist auch aus der
Es ist daher Aufgabe der vorliegenden Erfindung, ein Verfahren der eingangs genannten Art zu schaffen, mittels welchem die Schaumpartikel besonders energiegünstig thermisch miteinander verbunden werden können.It is therefore an object of the present invention to provide a method of the type mentioned, by means of which the foam particles can be thermally connected to each other particularly energy-efficient.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Ansprüchen angegeben.This object is achieved by a method having the features of patent claim 1. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the remaining claims.
Um ein Verfahren zum Herstellen eines Bauteils aus aus einem Kunststoff gebildeten Schaumpartikeln zu schaffen, bei welchem die Schaumpartikel besonders energiegünstig thermisch miteinander verbunden werden können, ist es erfindungsgemäß vorgesehen, dass die Schaumpartikel mittels induktiver Erwärmung thermisch miteinander verbunden werden. Mit anderen Worten wird Wärmeenergie zum thermischen Verbinden der Schaumpartikel durch Induktion beziehungsweise Induktionsheizen erzeugt und in die Schaumpartikel eingebracht.In order to provide a method for producing a component made of a plastic foam particles, in which the foam particles can be particularly thermally connected to each other thermally, it is provided according to the invention that the foam particles are thermally connected by means of inductive heating. In other words, thermal energy is generated for the thermal bonding of the foam particles by induction or induction heating and introduced into the foam particles.
Der Erfindung liegt die Idee zugrunde, jeweilige Berührungsflächen der Schaumpartikel durch die induktive Erwärmung besonders energiegünstig mit hinreichender Energie beziehungsweise Wärmeenergie zu versorgen, so dass dadurch eine jeweilige Oberfläche der Schaumpartikel angeschmolzen werden kann. Durch dieses Anschmelzen der Oberflächen kann eine Verschweißung beziehungsweise Sinterung der Berührungsflächen erfolgen, so dass die Schaumpartikel thermisch miteinander verbunden werden. Gegenüber herkömmlichen Verfahren lässt sich dabei eine verbesserte Energiebilanz bei der Herstellung des Bauteils realisieren. Darüber hinaus ermöglicht das erfindungsgemäße Verfahren die Darstellung einer sehr hohen und reproduzierbaren Bauteilqualität.The invention is based on the idea to supply respective contact surfaces of the foam particles by the inductive heating particularly energy-efficient with sufficient energy or heat energy, so that thereby a respective surface of the foam particles can be melted. As a result of this melting of the surfaces, welding or sintering of the contact surfaces can take place so that the foam particles are thermally bonded to one another. In comparison with conventional methods, an improved energy balance can be achieved during the production of the component. In addition, the inventive method allows the representation of a very high and reproducible component quality.
Mittels des erfindungsgemäßen Verfahrens können Bauteile, insbesondere für Kraftwagen, aus geschäumtem Kunststoff hergestellt werden. Insbesondere können Interieurbauteile, aber auch Exterieurbauteile hergestellt werden. Infolge der Herstellung aus geschäumtem Kunststoff lässt sich beispielsweise gegenüber Spritzgussverfahren eine Gewichtseinsparung von circa 50% realisieren.By means of the method according to the invention, components, in particular for motor vehicles, can be produced from foamed plastic. In particular, interior components, but also exterior components can be produced. As a result of the production of foamed plastic can be realized, for example, compared to injection molding a weight saving of about 50%.
Vorzugsweise wird als der Kunststoff, aus dem die Schaumpartikel gebildet sind, expandiertes Propylen (EPP) verwendet. Im Rahmen des erfindungsgemäßen Verfahrens lassen sich jedoch auch Partikel verwenden, welche aus einem anderen geschäumten Kunststoff wie beispielsweise expandiertem Polystyrol (EPS) gebildet sind.Preferably, expanded plastic (EPP) is used as the plastic from which the foam particles are formed. In the context of the method according to the invention, however, it is also possible to use particles which are formed from another foamed plastic, such as expanded polystyrene (EPS).
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung;Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing;
die Zeichnung zeigt in der einzigen Fig. eine schematische Darstellung eines Werkzeugs zum Durchführen eines Verfahrens zum Herstellen eines Bauteils aus aus einem Kunststoff gebildeten Schaumpartikeln, wobei die Schaumpartikel in eine Form des Werkzeugs eingebracht und mittels induktiver Erwärmung thermisch miteinander verbunden werden.the drawing shows in the single FIGURE is a schematic representation of a tool for performing a method for producing a component made of a plastic foam particles, wherein the foam particles are introduced into a mold of the tool and thermally interconnected by means of inductive heating.
