Die angeformten Plastelemente dienen zum Verbinden poroeser Werkstoffe, als Zier- oder Funktionselemente. Es ist Ziel der Erfindung, die Arbeitsproduktivitaet zu steigern, Arbeitszeit einzusparen, die Qualitaet durch hochfeste oberflaechenfertige Verbindungen und fehlerfreie Oberflaechen zu verbessern sowie durch das Verfahren neue konstruktiv-gestalterische Loesungen zu ermoeglichen. Es ist Aufgabe der Erfindung, ein Verfahren zu entwickeln, welches das Anformen von Plastwerkstoff ohne wesentliche Bearbeitung oder vorherige spezielle Behandlung der Werkstuecke ermoeglicht. Erfindungsgemaesz wird diese Aufgabe dadurch geloest, dasz ein unpolarer teilkristalliner Plastwerkstoff, beispielsweise Polyolefin,im thermoplastischen Zustand an einen poroesen Werkstoff angeformt wird, indem eine Werkzeughaelfte aus Metall oder dergleichen und die andere Haelfte der poroese Werkstoffe selbst die formgebende Kontur bilden und die spritzgiesztechnischen Verfahrensparameter so gewaehlt sind, dasz die Schmelze des Plastwerkstoffes ausreichend tief in die poroese Werkstoffstruktur eindringt.The molded plastic elements are used to connect porous materials, as ornamental or functional elements. It is an object of the invention to increase the labor productivity, save working time, to improve the quality of high-strength surface-ready compounds and flawless surfaces and to allow the process new constructive-creative solutions. It is an object of the invention to develop a method which allows the molding of plastic material without substantial processing or prior special treatment of the workpieces. According to the invention, this object is achieved by forming a non-polar semi-crystalline plastic material, for example polyolefin, in the thermoplastic state on a porous material by forming a tool half made of metal or the like and the other half of the porous materials themselves form the shaping contour and the injection molding process parameters It is chosen that the melt of the plastic material penetrates sufficiently deep into the porous material structure.
