FormeinlageForm insert
Die Erfindung betrifft eine Formeinlage zur Verwendung als artikelspezifische Zwischenlage, die im Tiefziehverfahren hergestellt ist.The invention relates to a mold insert for use as an article-specific intermediate layer, which is produced by the deep-drawing process.
Grundsätzlich ist es bekannt, derartige Formeinlagen aus Kunststoff im Thermoformverfahren in einer Vielzahl von verschiedenen Materialien herzustellen.In principle, it is known to produce such mold inserts made of plastic using the thermoforming process in a variety of different materials.
Bei der Herstellung ■ von Formeinlagen der eingangs genannten Art im Tiefziehverfahren ist es bekannt, als Kunststoff entweder Polycarbonat (PC) oder Acrylnitril-Butadien-Styrole (ABS), genauer Acrylnitril-Butadien-Styrol-Terpolymere zu verwenden. In Abhängigkeit vom Einsatzzweck werden Formeinlagen aus dem Material mit den gewünschten Eigenschaften geschaffen. So zeichnet sich PC beispielsweise durch eine besonders hohe Festigkeit, Härte und Zähigkeit aus. ABS zeichnet sich neben einer hohen Schlag- und Kerbschlagfähigkeit und einer hohen Zähigkeit auch durch ein gutes Schalldämpfungsvermögen aus.When producing mold inserts of the type mentioned above using the deep-drawing process, it is known to use either polycarbonate (PC) or acrylonitrile-butadiene-styrene (ABS), or more precisely acrylonitrile-butadiene-styrene terpolymers, as the plastic. Depending on the intended use, mold inserts are made from the material with the desired properties. For example, PC is characterized by particularly high strength, hardness and toughness. ABS is characterized by high impact and notch impact resistance and high toughness, as well as good sound-damping properties.
Der Erfindung liegt die Aufgabe zugrunde, eine Formeinlage der eingangs genannten Art zu schaffen, die besonders günstige Eigenschaften aufweist.The invention is based on the object of creating a mold insert of the type mentioned at the beginning, which has particularly favorable properties.
Die Lösung dieser Aufgabe erfolgt mit einer Formeinlage mit den Merkmalen des Pamspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved with a mold insert having the features of claim 1. Advantageous developments of the invention are specified in the subclaims.
Erfindungswesentlich ist, daß die zur Verwendung als artikelspezifische Zwischenlage gedachte Formeinlage aus einem Blend von PC und ABS im Tiefziehverfahren hergestellt ist.What is essential to the invention is that the mold insert intended for use as an article-specific intermediate layer is made from a blend of PC and ABS using a deep-drawing process.
Gegenüber reinen ABS Formeinlagen wird eine optimierte Schlagzähigkeit, insbesondere bei niedrigen Temperaturen, außerdem eine verbesserte Wärmeformbeständigkeit, eine höhere UV-Lichtbeständigkeit und ein günstigeres Abriebverhalten erreicht. Gegenüber aus PC hergestellten Formeinlagen wird mit der erfindungsgemäßen Formeinlage insbesondere ein besseres Schalldämpfungsvermögen, eine geringere Spannungsrißneigung und eine optimierte Öl- und Fettbeständigkeit erreicht.Compared to pure ABS mold inserts, an optimized impact strength is achieved, especially at low temperatures, as well as improved heat resistance, higher UV light resistance and more favorable abrasion behavior. Compared to mold inserts made from PC, the mold insert according to the invention achieves in particular better sound-damping capacity, a lower tendency to stress cracking and optimized oil and grease resistance.
Bevorzugt ist der Blend so zusammengesetzt, daß der Anteil des Polycarbonats (PC) größer ist als der Anteil des Acrylnitril-Butadien-Styrols (ABS). In einer besonders bevorzugten Ausführungsform ist der PC Anteil größer als 65% oder in einer Weiterentwicklung sogar größer als 85%. In einer derartigen Zusammensetzung ist eine in den Eigenschaften besonders gute Mischung erzielbar.The blend is preferably composed in such a way that the proportion of polycarbonate (PC) is greater than the proportion of acrylonitrile butadiene styrene (ABS). In a particularly preferred embodiment, the PC proportion is greater than 65% or, in a further development, even greater than 85%. In such a composition, a mixture with particularly good properties can be achieved.
