Abstract

Selon l'invention, on obtient des pièces moulées en résine synthétique, telles que des panneaux et des portes, présentant un fini amélioré imitant le grain du bois, en revêtant (4) d'abord une partie de toute la surface du moule (1) à l'aide d'au moins un colorant dont la couleur diffère de la couleur de la résine cuite, puis en essuyant la surface du moule. De façon inattendue, cette dernière opération favorise la concentration du colorant sur les sommets et les points élevés du moule, et par conséquent dans les creux de la pièce moulée ainsi obtenue.
