Title
(DE) VERFAHREN ZUR ERZEUGUNG VON VIRTUELLEN DREIDIMENSIONALEN MUSTERN IN FORMKÖRPERN AUS KUNSTSTOFF
(EN) METHOD FOR PRODUCING VIRTUAL THREE-DIMENSIONAL PATTERNS IN MOLDED BODIES MADE OF PLASTIC
(FR) PROCÉDÉ DE PRODUCTION DE MOTIFS VIRTUELS TRIDIMENSIONNELS DANS DES CORPS MOULÉS EN PLASTIQUE
Abstract
(DE)
Die vorliegende Erfindung betrifft ein zweistufiges Verfahren zur Erzeugung von virtuellen dreidimensionalen Mustern in polymeren Formkörpern mit Hilfe von Spritzgießverfahren, insbesondere ein Verfahren, bei dem ein übliches Spritzgießverfahren mit einem reaktiven Spritzgießverfahren in geeigneter Weise kombiniert werden um polymere Formkörper mit einem an einer Oberfläche sichtbaren virtuellen dreidimensionalen Muster, welches durch plättchenförmige Effektpigmente gebildet wird, zu erhalten, sowie die mittels dieses Verfahrens erzeugten polymeren Formkörper und deren Verwendung, insbesondere für dekorative Zwecke.
(EN)
The invention relates to a two-stage method for producing virtual three-dimensional patterns in polymer molded bodies by means of injection-molding methods, in particular a method in which a conventional injection-molding method is combined with a reactive injection-molding method in a suitable way in order to obtain polymer molded bodies having a virtual three-dimensional pattern visible at a surface, which pattern is formed by platelet-shaped effect pigments. The invention further relates to the polymer molded bodies produced by means of said method and to the use of said polymer molded bodies, in particular for decorative purposes.
(FR)
L'invention concerne un procédé en deux étapes pour la production de motifs virtuels tridimensionnels dans des corps moulés polymères à l'aide de procédés de moulage par injection, notamment un procédé selon lequel un procédé de moulage par injection classique est combiné de façon appropriée à un procédé de moulage par injection réactif pour obtenir des corps moulés polymères présentant un motif virtuel tridimensionnel visible sur une surface, formé par des pigments à effet en forme de plaquettes. L'invention concerne également les corps moulés polymères produits au moyen de ce procédé, et leur utilisation, notamment à des fins décoratives.
