  • One of the traditional methods of forming lines is usually direct surface printing, surface coating, direct plating or two-color injection molding. These methods are difficult to form a consistent color pattern on various curved surfaces, curved surfaces or inclined surfaces. The process is clearly not suitable for today's needs.
  • the third is IMR (In Molding Roller) molding technology, which is to put the printed film into a metal mold, automatically convey the positioning by the foil feeding machine, and then inject the molding resin into the metal mold.
  • the film is joined to separate the pattern originally printed on the film from the film, and is transferred to a forming method in which the resin is integrated.

Abstract

La présente invention concerne un procédé de formation d'un grain tridimensionnel (3) sur la pièce en plastique (1) et des produits correspondants. Dans le procédé, on prépare au préalable un moule sur lequel se trouve le grain tridimensionnel (3). On dépose ensuite une couche de matière colloïdale photopolymérisable (2) sur le grain tridimensionnel (3) du moule. Une pièce en plastique (1) est déposée sur la couche de matière colloïdale photopolymérisable (2). Après avoir laminé et égalisé la pièce en plastique (1) on la photopolymérise puis on la sort du moule, ce qui produit ainsi une pièce en plastique (1) comportant une couche de matière colloïdale photopolymérisée (2) à grain tridimensionnel (3). On forme ensuite un revêtement photomodifié (4) sur la pièce en plastique (1) comportant une couche de matière colloïdale photopolymérisée (2) à grain tridimensionnel (3) par électrodéposition sous vide ou revêtement par pulvérisation directe. Après la formation du film, on place le côté de la pièce en plastique (1) comprenant la couche de matière colloïdale photomodifiable (2), dans le moule où la matière colloïdale photopolymérisée est injectée puis laminée et photopolymérisée et enfin sortie du moule, de sorte qu'une autre couche photopolymérisée (5) à surface égalisée soit formée sur le revêtement photomodifié (4), ce qui produit ainsi la pièce en plastique (1) à grain tridimensionnel (3).
