Abstract

Procédé de moulage de pièce en matière plastique recyclée de couleur sombre (1), par dessus une autre pièce de couleur plus vive (2) de manière à lui donner sur une partie de sa surface une zone plus visible satisfaisant les préoccupations de sécurité. Le procédé est notamment appliqué à la fabrication de plots de stabilisation de panneaux de signalisation temporaires ou de barrières de chantier. Le procédé consiste à insérer préalablement dans la cavité du moule de mise en forme de la matière recyclée de couleur sombre une autre pièce de couleur plus vive. Cette dernière est conçue de telle sorte qu’elle est calée par ses formes à l’intérieur de la cavité, ce qui la préserve de tout mouvement lorsqu’elle subit l’arrivée du flux de la matière recyclée. D’autres formes spécifiques lui permet d’être retenues par la matière recyclée sans possibilité de désolidarisation une fois le moulage terminé. Figure pour l’abrégé : fig. 1Method of molding a dark colored recycled plastic part (1), over another brighter colored part (2) so as to give it on part of its surface a more visible area satisfying safety concerns. The process is notably applied to the manufacture of stabilizer studs for temporary traffic signs or site barriers. The process consists of inserting beforehand into the cavity of the mold for shaping the dark-colored recycled material another part of a brighter color. The latter is designed in such a way that it is wedged by its shapes inside the cavity, which preserves it from any movement when it undergoes the arrival of the flow of recycled material. Other specific shapes allow it to be retained by the recycled material without the possibility of detachment once the molding is finished. Figure for abstract: fig. 1
