L'invention porte sur un procédé de production de pièces moulées à surface finie comprenant des tissus non tissés par le revêtement, dans lequel le revêtement de la ou les surfaces de moules de tissu non tissé à finir est exécuté avec une résine thermodurcissable ou un mélange de résine et durcisseur de concert avec une stratification, et les pièces ainsi produites sont chauffées à des températures plus élevées que celle du point de fusion et plus élevées que la température du commencement de la réaction de durcissement de la résine thermodurcissable utilisée et refroidie après le durcissement du revêtement.
