Abstract

L'invention concerne un procédé de moulage par injection de pièces en matière plastique possédant des zones colorées. Selon ce procédé, on plastifie une masse de matière de coloration honogène, on maintient cette masse plastifiée dans un état non comprimé à l'intérieur d'une enceinte rigide, on injecte pendant ce maintien dans un état non comprimé, des petites quantités de matières colorantes en des endroits précis dans la masse plastifiée et on injecte ensuite la masse plastifiée dans un moule par application de pression sur cette masse L'invention s'applique en particulier à la fabrication d'objets possédant des zones colorées bien localisées tels que des fleurs artificielles.
