Abstract

A thermoformed and printed film (4) is placed in an open first molding tool part (2). The tool is then closed by a second tool part with part of a heat embossed film (5). Plastic is then introduced into the closed tool via a runner (3) which guides it between the two films.

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung von Kunststoffteilen mit beidseitiger Dekoration.The present invention relates to a process for the production of plastic parts with double-sided Decoration.

Derartige transparente Kunststoffteile dienen beispielsweise als Displayfenster bzw. Dekorblenden bei Mobiltelefonen.Such transparent plastic parts are used, for example, as display windows or decorative panels on mobile phones.

Es ist bekannt, derartige transparente Kunststoffteile einseitig zu dekorieren. Dazu werden unterschiedliche Techniken verwendet, wie z. B. Siebdruck, IMD (In Mold Decoration), IMF (In Mold Foil Decoration – Folienhinterspritzen) oder Tampondruck. Das bedeutet, dass bei einer beidseitigen Dekoration mehrere Verfahrensschritte notwendig sind. Dieses führt zu einer teueren und aufwendigen Herstellung derartiger Kunststoffteile.It is known to be transparent Decorate plastic parts on one side. This will be different Techniques used such. B. screen printing, IMD (In Mold Decoration), IMF (In Mold Foil Decoration) or pad printing. That means that with a double-sided decoration several process steps are necessary. This leads to one expensive and complex manufacture of such plastic parts.

Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zur Herstellung von Kunststoffteilen mit einer beidseitigen Dekoration anzugeben, bei welchem die Prozessschritte reduziert sind und so eine Kostenreduktion bei der Herstellung erreicht werden kann.Object of the present invention is therefore a process for the manufacture of plastic parts to indicate with a decoration on both sides, in which the process steps are reduced and thus a cost reduction in production can be achieved can.

Diese Aufgabe wird erfindungsgemäß bei dem eingangs genannten Verfahren dadurch gelöst, dass in einer einseitig offenen ersten Form eine entsprechend tiefgezogene und bedruckte Folie wie sie beim Folienhinterspritzen Verwendung findet, eingelegt wird, dass diese erste Form mittels einer zweiten Form mit einem Teil einer entsprechend bedruckten Heißprägefolie geschlossen wird, und dass über eine Angussöffnung die so geschlossene Form mit einem Kunststoff gefüllt wird.This object is achieved in the The above-mentioned method is solved in that in a one-sided open first form a correspondingly deep-drawn and printed Foil as it is used for film injection molding, inserted is that this first form by means of a second form with a Part of an appropriately printed hot stamping foil is closed, and that about a gate the closed form is filled with a plastic.

Bei dem erfindungsgemäßen Herstellungsverfahren wird die Anzahl der Prozessschritte reduziert, da eine Verbindung zweier Dekorationstechnologien angewendet wird. Hierdurch ergibt sich eine erhebliche Kostenreduktion bei der Herstellung von beidseitig dekorierten Kunststoffteile.In the manufacturing method according to the invention the number of process steps is reduced because of a connection two decoration technologies is applied. This results in a significant cost reduction in the manufacture of both sides decorated plastic parts.

Weitere Ausgestaltungen des erfindungsgemäßen Herstellungsverfahrens ergeben sich aus den Unteransprüchen sowie aus der nachfolgenden Beschreibung eines beispielhaften Verfahrens zur Herstellung von beidseitig dekorierten Kunststoffteilen anhand eines in der Figur dargestellten Werkzeugs zur Durchführung des erfindungsgemäßen Verfahrens.Further refinements of the manufacturing method according to the invention result from the subclaims and from the following description of an exemplary method for the production of plastic parts decorated on both sides of a tool shown in the figure for performing the inventive method.

Das Werkzeug zur Durchführung des erfindungsgemäßen Verfahrens ist in der Figur lediglich prinzipiell dargestellt, da der eigentliche Erfindungsgedanken nicht detaillierte Ausführungsformen des Werkzeugs betrifft. Das Werkzeug besteht im wesentlichen aus einem Spritzgusswerkzeug 1, welches unter anderem eine erste Form 2 aufweist, welche der Form des herzustellenden Kunststoffteils entspricht.The tool for carrying out the method according to the invention is only shown in principle in the figure, since the actual inventive concept does not relate to detailed embodiments of the tool. The tool essentially consists of an injection molding tool 1 which among other things a first form 2 has, which corresponds to the shape of the plastic part to be produced.

In diese Form wird eine tiefgezogene und bedruckte Folie 4, wie sie beim Folienhinterspritzen Verwendung findet, eingelegt. Danach wird diese Form mittels einer zweiten Form in Verbindung mit einer Heißprägefolie, wie sie beim In Mold Decoration-Verfahren Verwendung findet, geschlossen, wobei das Verschlussteil selber, d. h. die zweite Form eine vorgegebene dem herzustellenden Kunststoffteil entsprechende Kontur aufweist.A thermoformed and printed film is in this form 4 , as used in film injection molding. Then this mold is closed by means of a second mold in connection with a hot stamping foil, such as is used in the in-mold decoration process, the closure part itself, ie the second mold, having a predetermined contour corresponding to the plastic part to be produced.

Danach wird über eine Angussöffnung 3 der eigentliche Spritzvorgang durchgeführt, das heißt die geschlossene Form wird mit einem Kunststoff gefüllt.After that, a sprue is opened 3 the actual spraying process is carried out, i.e. the closed mold is filled with a plastic.

Bei dem erfindungsgemäßen Herstellungsverfahren werden also zwei Dekorationstechnologien, nämlich die IMD (In Mold Decoration)-Technologie und die IMF (In Mold Foil Decoration)-Technologie miteinander verbunden.In the manufacturing method according to the invention are two decoration technologies, namely IMD (In Mold Decoration) technology and IMF (In Mold Foil Decoration) technology.

Abschließend ist noch festzustellen, dass hier unter einer Dekoration nicht nur lediglich ein Bedrucken der entsprechenden Oberflächen von Kunststoffteilen zu verstehen ist, sondern dass die Dekoration auch eine funktionelle Oberfläche, wie z. B. ein Hardcoat, sein kann.Finally, it should be noted that here under a decoration not just a print the corresponding surfaces of plastic parts is understood, but that the decoration also a functional surface, such as B. can be a hard coat.
