Weitere Anwendungsgebiete der Erfindung sind Elektrogeräte, Audio- und Videogeräte sowie Gebäudeleitsysteme.field of use The invention relates to thermoplastic parts with transilluminable structures or symbols. This is especially true in motor vehicles for switches, Controls, dashboards, logos, emblems and the like. These thermoplastic parts are usually not galvanisable. Of the Use of galvanic surfaces However, it is sought for design reasons. The fluoroscopy The icons are required as day / night design. Further applications of the invention are electrical appliances, Audio and video devices as well Building management systems.

Tag/Nacht-Design-Thermoplastteile lassen sich in einem Zweikomponentenspritzgießverfahren herstellen, einerseits aus einem klaren oder transluzenten Polycarbonat und andererseits aus einem Acrylnitril-Butadien-Styrol-Copolymer. Die Zweikomponentenspritzgießtechnik ist sehr aufwendig. Außerdem muß für jedes Symbol eine besondere Werkzeugausbildung gefertigt werden.Day / night design thermoplastic parts can be produced in a two-component injection molding process, on the one hand from a clear or translucent polycarbonate and on the other hand of an acrylonitrile-butadiene-styrene copolymer. The two-component injection molding technique is very expensive. Furthermore must for each Symbol to be crafted a special tool training.

Derartige Thermoplastteile lassen sich auch durch Lackieren von Polycarbonatteilen oder Polymethylmethacrylatteilen und Auslasern einer Struktur herstellen. Dieses Verfahren gibt dem Designer ein hohes Maß an Gestaltungsmöglichkeit.such Thermoplastic parts can also be painted by painting polycarbonate parts or polymethyl methacrylate parts and lasers of a structure. This method gives the designer a high degree of design options.

Ferner ist die IMD-Technik (In Mould Decoration) bekannt, wonach eine farbig lackierte oder bedruckte PC-Folie hinterspritzt wird. Hierbei wird die Folie als Ganzes beleuchtet. Eine metallische Oberfläche läßt sich nicht realisieren.Further is the IMD technique (In Mold Decoration) known, after which a colored painted or printed PC film is back-injected. This is illuminated the film as a whole. A metallic surface can be do not realize.

Insgesamt ist es nicht möglich, metallische Oberflächen auf solchen durchleuchtbaren Thermoplastteilen zu verwirklichen.All in all it is impossible, metallic surfaces on such transmittable thermoplastic parts.

Aufgabenstellungtask

Aufgabe der Erfindung ist die Bereitstellung solcher Thermoplastteile mit hochwertiger metallischer Oberfläche und mit durchleuchtbaren Symbolen für ein Tag/Nacht-Design. Diese Aufgabe wird durch ein durchleuchtbares Thermoplastteil mit den Merkmalen nach Anspruch 1 gelöst.task The invention is the provision of such thermoplastic parts with high quality metallic surface and with translucent symbols for a day / night design. These Task is by a transilluminous thermoplastic part with the features solved according to claim 1.

Die Erfindung unterscheidet sich insofern vom Stand der Technik, als der galvanisierbare Kunststoff in einfacher Weise auf das Thermoplastteil aufgebracht werden kann. Eine Laserung dieser Kunststoffschicht ist ohne weiteres möglich, so dass ein Spalt als durchleuchtbare Struktur aus der Kunststoffschicht herausgeschnitten werden kann. Im Bereich dieses Spaltes fehlt der galvanisierbare Kunststoff, so dass sich dort keine Galvanikschicht ausbildet. Infolgedessen ist dieser Bereich durchleuchtbar.The The invention differs from the prior art in that the electroplatable plastic applied in a simple manner to the thermoplastic part can be. A laser of this plastic layer is easy possible, leaving a gap as a translucent structure from the plastic layer can be cut out. In the area of this gap is missing the Electroplatable plastic, so that there is no galvanic layer formed. As a result, this area is transilluminable.

Ein besonders effektive Galvanisierung wird dadurch ermöglicht, dass als galvanisierbarer Kunststoff ein Acrylnitril-Butadien-Styrol-Copolymeres (ABS) eingesetzt wird.One particularly effective galvanization is made possible by in that an acrylonitrile-butadiene-styrene copolymer (ABS) is used as the electroplatable plastic is used.

Eine einfache Verfahrensführung wird dadurch erreicht, dass das ABS als Lack aufgebracht wird.A simple process management is achieved by applying the ABS as a paint.

Die Erfindung stellt somit ein durchleuchtbares Thermoplastteil aus einem tranparenten, amorphen Kunststoff, derart zur Verfügung, dass in einer den amorphen Kunststoff überdeckenden, opaken Schicht aus einem galvanisierbaren Kunststoff die Symbole als Muster ausgebildet sind und dass eine Galvanikschicht die Kontur der Muster freiläßt.The Invention thus constitutes a transilluminable thermoplastic part a transparent, amorphous plastic, so available that in an opaque layer covering the amorphous plastic made of a galvanisable plastic symbols designed as a pattern are and that a galvanic layer leaves the contour of the pattern.

Ausführungsbeispielembodiment

Ein Ausführungsbeispiel wird anhand der Zeichnung erläutert, in der darstellen:One embodiment will be explained with reference to the drawing, in the picture:

2 einen ersten Verfahrensschritt, 2 a first process step,

3 die Aufbringung eines galvanisierbaren Kunststoffs, 3 the application of a galvanisable plastic,

4 die Herstellung von Symbolen durch einen Laserstrahl und 4 the production of symbols by a laser beam and

5 das fertige Thermoplastteil. 5 the finished thermoplastic part.

1 zeigt ein Thermoplastteil 1 aus einem transparenten oder durchscheinenden, amorphen Kunststoff. Es handelt sich z. B. um einen Schalterknopf, um ein Wippenfeld, um eine Armaturentafel, um eine Hinweistafel oder dergleichen. Dieser Kunststoff ist nicht galvanisierbar. 1 shows a thermoplastic part 1 from a transparent or translucent, amorphous plastic. It is z. Example, to a switch button to a rocker panel to a dashboard to a billboard or the like. This plastic is not galvanisable.

In einem ersten Verfahrensschritt nach 2 wird auf das Thermoplastteil 1 eine opake Lackschicht 2 aufgetragen. Auf diese opake Lackschicht 2 wird nach 3 eine Lackschicht 3 aus einem galvanisierbaren Kunststoff wie einem Acrylnitril-Butadien-Styrol-Copolymeren (ABS) aufgebracht. Bei Einsatz eines opaken galvanisierbaren Thermoplast ist eine Schicht ausreichend. Die Lackschichten 2 und 3 sind im Vergleich zu dem Thermoplastteil 1 zu dick dargestellt. Insofern ist die Zeichnung nicht maßstäblich.In a first step after 2 is on the thermoplastic part 1 an opaque lacquer layer 2 applied. On this opaque lacquer layer 2 is after 3 a paint layer 3 made of an electroplatable plastic such as acrylonitrile-butadiene-styrene copolymer (ABS). When using an opaque electroplatable thermoplastic, one layer is sufficient. The paint layers 2 and 3 are compared to the thermoplastic part 1 shown too thick. In this respect, the drawing is not to scale.

In einem weiteren Verfahrensschritt nach 4 wird durch einen Material verdrängenden oder verbrennenden Laserstrahl 4 eines Lasergeräts 5 ein Symbol 6 oder eine Struktur in die Lackschichten 2, 3 eingebrannt. Der Laserstrahl dringt bis auf die Tiefe des Lackschicht vor und schädigt die darunterliegende Schicht nicht. Eine solche Steuerung des Laserstrahl ist möglich.In a further process step 4 is caused by a material displacing or burning laser beam 4 a laser device 5 a symbol 6 or a structure in the paint layers 2 . 3 baked. The laser beam penetrates to the depth of the paint layer and does not damage the underlying layer. Such control of the laser beam is possible.

Schließlich erfolgt nach 5 die Ausbildung einer Galvanikschicht nach standardisierten Verfahren. Nach Anbeizen der Oberfläche erfolgt eine elektrolytische Vorvernickelung. Darauf werden weitere Schichten aus Kupfer, Nickel, Glanzni ckel und Chrom galvanisch aufgebracht. Da im Bereich der Symbole keine elektrisch leitende Schicht vorhanden ist, erhält man dort einen durchleuchtbaren Bereich. Die Chromschicht der Oberfläche wird optisch und haptisch als hochwertig empfunden.Finally, after 5 the formation of a galvanic layer according to standardized methods. After pickling the surface, an electrolytic nickel plating takes place. Then further layers of copper, nickel, Glanzni ckel and chrome are applied galvanically. Since there is no electrically conductive layer in the area of the symbols, a translucent area is obtained there. The chrome layer of the surface is optically and haptically perceived as high quality.
