Es ist bereits bekannt, gepreßte oder gegossene Formstücke aus Kunstharz nach dem Schoopschen Verfahren zu metallisieren. Die so aufgebrachte dünne Metallschicht wird beim nachträglichen Polieren häufig unbeabsichtigterweise durchgeschliffen, wodurch der Gegenstand unbrauchbar wird. Zur Vermeidung des Übelstandes können dicke Metallschich'sn aufgespritzt werden, die jedoch den Gegenstand meist unzulässig schwer, für eine etwa beabsichtigte nachträgliche Galvanisierung ungeeignet und außerdem, zu teuer machen.It is already known to press or cast resin moldings after Schoop's method of metallizing. The thin metal layer applied in this way is often unintentionally sanded through during subsequent polishing, which causes the Object becomes unusable. To avoid the inconvenience, thick layers of metal can be used be sprayed on, which, however, usually makes the object impermissibly difficult for a any intended subsequent electroplating is unsuitable and, moreover, too expensive do.

Abhilfe wird durch vorliegende Erfindung · dadurch geschaffen, daß Metalle mit nicht zu hohem Schmelzpunkt, wie Zink, Zinn, Blei, Wismut, Kadmium usw., oder deren Legierungen (auch Aluminium kann zulegiert sein) auf das Kunstharzpreßteil aufgespritztThe present invention provides a remedy in that metals do not have too high melting point, such as zinc, tin, lead, bismuth, cadmium, etc., or their alloys (aluminum can also be alloyed) sprayed onto the synthetic resin molded part

ao werden — bevorzugterweise werden Legierungen verwendet, deren Schmelzpunkt in der Nähe des Schmelzpunktes des Edelharzpreßlings, also meist um 16o° herum, liegt (z. B. das bekannte Woodsche Metall) —, und daß dann der Preßling erneut, also zum zweitenmal, in eine erhitzte Preßform eingebracht wird, so daß die hochglanz polierte Oberfläche der erhitzten Preßform, im nachfolgenden Niederschmelzform genannt, die dünne Metallhaut niedersc'hmilzt oder mindestens ein " Aneinanderschmelzen der kleinsten Metallteilchen bewirkt. Die Metallhaut wird hierdurch erheblich verfestigt, sie wird gleichsam inao will - preferred will be alloys used whose melting point is close to the melting point of the high-grade resin molding, so mostly around 16o °, lies (e.g. the well-known Wood's metal) - and that then the compact again, that is to say for the second time, is introduced into a heated mold is so that the mirror polished surface of the heated mold, in the following Called a low-melt form, which lowers the thin metal skin or at least one "This causes the smallest metal particles to melt together. This causes the metal skin considerably solidified, it becomes, as it were, in

den Kunstharzpreßling hineingepreßt, wodurch ein festes Haften der Metallhaut an diesem, ferner Beseitigung der vorhandenen Porosität und eine Glättung der Außenfläche erzielt wird.pressed in the synthetic resin molding, whereby a firm adhesion of the metal skin to this, furthermore, the existing porosity is eliminated and the outer surface is smoothed is achieved.

Die Niederschmelzform unterscheidet sich von der Preßform um die Dicke der Metallhaut; es kann in manchen Fällen die ursprüngliche Preßform als Xiederschmelzform verwendet werden, namentlich, wenn der durch Erkaltung zusammengezogene Preßling in die durch Erhitzung ausgedehnte Preßform eingebracht wird.The meltdown mold differs from the compression mold by the thickness of the metal skin; the original die can be used as the low-melt mold in some cases are, in particular, when the compact, which has been contracted by cooling, is introduced into the mold, which has been expanded by heating will.

Nach der Erfindung können z. B. Geschirre aller Art, z. B. die Außenseite oder Innenseite von Tassen oder Füllhalter oder elektrische Stecker und Steckdosen, ferner die Innenseite von Reflektoren, z. B. solche von Fahrradlampen oder Spiegeln aller Art, z. B. solche von Puderdosen, hergestellt werden, wie auch zahllose andere Gebrauchsgegenstände. According to the invention, for. B. harnesses of all kinds, e.g. B. the outside or inside of cups or fountain pens or electrical plugs and sockets, furthermore the inside of reflectors, e.g. B. those of bicycle lamps or mirrors of all kinds, z. B. those of powder compacts, are made, as well as countless other everyday objects.
