Abstract
Description
Die Erfindung betrifft ein partiell galvanisierbares Polymerenformteil.The invention relates to a partially galvanizable molded polymer part.
Die DE 44 12 126 C2 beschreibt ein derartiges Polymerenformteil, dessen durch Nuten getrennte Teilbereiche eine chemisch abgeschiedene Metallschicht aufweisen. Die zu galvanisierenden Teilbereiche werden in einemm galvanischen Bad an eine elektrische Spannung angeschlossen, so daß diese Teilbereiche zur Erzeugung einer hochwertigen Galvanikschicht partiell galvanisiert werden können. Die Nuten zwischen den Teilbereichen dienen einerseits der optischen Trennung und bilden andererseits eine Begrenzung der chemisch abgeschiedenen Metallschicht, so daß die Metallschichten der Teilbereiche für die Elektroplattierung partiell aufgeladen werden können. Die chemische Metallabscheidung stellt einen zusätzlichen Aufwand in der Herstellung dar, insbesondere, wenn die chemische Metallabscheidung in einzelnen Teilbereichen wieder abgetragen werden muß.DE 44 12 126 C2 describes such a molded polymer part, the one separated by grooves Partial areas have a chemically deposited metal layer. The sub-areas to be electroplated are connected to an electrical voltage in a galvanic bath, so that these partial areas can be partially galvanized to produce a high-quality electroplating layer. The grooves between the sub-areas serve on the one hand for optical separation and on the other hand form a boundary the chemically deposited metal layer, so that the metal layers of the partial areas for the Electroplating can be partially charged. Chemical metal deposition represents an additional one Manufacturing effort represents, especially if the chemical metal deposition in individual Partial areas must be removed again.
Aufgabe der Erfindung ist eine solche Ausbildung des Formteil, daß einzelne Teilbereiche unmittelbar partiell galvanisierbar sind.The object of the invention is such a formation of the molded part that individual areas immediately are partially galvanizable.
Diese Aufgabe wird mit einem Polymerenformteil gelöst, dsssen Teilbereiche aus galvanisierbaren oder nichtgalvanisierbaren Polymeren bestehen und durch Nuten mit V-förmigem Profil voneinander getrennt sind, wobei die aus galvanisierbaren Polymeren bestehenden Teilbereiche eine galvanische Beschichtung aufweisen.This object is achieved with a molded polymer part, the partial areas of which can be galvanized or non-galvanizable polymers and by grooves with a V-shaped profile from each other are separated, the partial areas consisting of galvanizable polymers being a galvanic coating exhibit.
Die Erfindung unterscheidet sich insofern vom Stand der Technik, als die Teilbereiche des Polymerenformteils aus auf die jeweilige Behandlung optimal abgestimmten Polymeren bestehen, so daß Schutzbehandlungen, Abdeckungen und Entfernung von Schichten entfallen. Behandlungen zur Erzeugung anderer dekorativer Schichten sind ohne Zwischenstufen möglich.The invention differs from the prior art in that the partial areas of the molded polymer part consist of polymers optimally matched to the respective treatment, so that Protective treatments, covers and removal of layers are eliminated. Generation treatments other decorative layers are possible without intermediate stages.
Die Aufbringung der Galvanikschicht wird dadurch erleichtert, daß die aus galvanisierbaren Polymeren bestehenden Teilbereiche jeweils eine Lasche zum Anschluß einer Kontaktzange aufweisen.The application of the electroplating layer is facilitated by the fact that the electroplated polymers existing sections each have a tab for connecting a contact pliers.
Für die galvanische Bahandlung ist ein galvanisierbares Polymeres aus der Gruppe von ABS (Acrylnitril-Butadien-Styrol-Copolymere), ABS.PC-Gemische (Acrylnitril-Butadien-Styrol.Polycarbonat-Copolymere). A galvanizable polymer from the group of ABS is used for galvanic treatment (Acrylonitrile-butadiene-styrene copolymers), ABS.PC blends (acrylonitrile-butadiene-styrene.polycarbonate copolymers).
Geeignet ist auch ein in einem modifizierten galvanischen Bad galvanisierbares Polymeres wie PA (Polyamid). Man kann so hochwertige Galvanikschichten herstellen.A polymer such as PA, which can be galvanized in a modified galvanic bath, is also suitable (Polyamide). High quality electroplating layers can be produced in this way.
Für das nichtgalvanisierbare Formteil wird ein säureresistentes, nichtgalvanisierbares Polymeres wie PC (Polycarbonat) und Polyvinylchlorid (PVC) vorgeschlagen.An acid-resistant, non-galvanizable polymer is used for the non-galvanizable molded part such as PC (polycarbonate) and polyvinyl chloride (PVC).
Zur Herstellung einer partiell galvanisierbaren Polymerenformteils wird vorgeschlagen, daß nach einem Zweikomponentenverfahren zunächst in einer ersten Kavität einer Spritzgießmaschine ein Vorformteil aus einem galvanisierbaren bzw. nicht galvanisierbaren Polymeren geformt wird, daß danach in einer zweiten, das Vorformteil aufnehmenden Kavität der Spritzgießmaschine ein Zusatzformteil aus einem nicht galvanisierbaren bzw. galvanisierbaren Polymeren geformt wird und daß schließlich die Oberflächen des galvanisierbaren Polymeren galvanisiert werden.To produce a partially galvanizable molded polymer part, it is proposed that after In a two-component process, a preform is first placed in a first cavity of an injection molding machine is formed from a galvanizable or non-galvanizable polymer that thereafter in a second, the preform receiving the cavity of the injection molding machine from an additional molding a non-galvanizable or galvanizable polymer is formed and that finally the surfaces of the galvanizable polymer.
Alternativ wird für die Herstellung vorgeschlagen, daß ein Vorformteil aus einem galvanisierbaren bzw. nicht galvanisierbaren Polymeren in eine Kavität einer Spritzgießmaschine eingelegt und ein Zusatzformteil aus einem nicht galvanisierbaren bzw. galvanisierbaren Polymeren geformt wird und daß schließlich die Oberflächen des galvanisierbaren Polymeren galvanisiert werden.Alternatively, it is proposed for the production that a preform from a galvanizable or non-galvanizable polymers placed in a cavity of an injection molding machine and an additional molded part is formed from a non-galvanizable or galvanizable polymer and that finally the surfaces of the galvanizable polymer are galvanized.
