Abstract

La présente invention concerne un procédé de moulage d'articles multicolores en acétate d'éthyle et de vinyle (AEV), comprenant les étapes consistant à : injecter dans une première impression (11) de l'AEV d'une première couleur pour mouler une première partie (14) d'un article multicolore devant être obtenu, la partie inférieure du moule (12) et la première partie supérieure du moule (13) étant à une température inférieure au point de fusion de l'AEV ; ouvrir le moule ; fermer la partie inférieure du moule (12) avec une seconde partie supérieure du moule (15) ayant une température plus élevée que la température de réticulation de l'AEV, afin de former une seconde impression (16) qui est complémentaire de la première et est adaptée pour donner une seconde partie (17) de l'article devant être obtenu ; injecter l'AEV d'une seconde couleur de façon à surmouler sur la première partie (14) la seconde partie (17) de l'article à fournir, et chauffer simultanément la partie inférieure du moule (12) à une température plus élevée que la température de réticulation ; lorsque la réticulation est finie, ouvrir le moule et extraire l'article. Au moins une des parties du moule (12, 13, 15) est façonnée afin de former, avec sa partie complémentaire, une bavure (18) autour de l'impression correspondante.
