Abstract

Selon un perfectionnement à la demande de brevet principal n degrés 78 32327, la membrane de résine pure exempte de charge (par exemple de silicone) et qui sert de demi-maquette pour la partie inférieure du moule est rendue détachable de la couche sous-jacente de résine chargée à au moins 80 % de poudre, par exemple par application d'un vernis d'isolation sur ladite couche avant le coulage par injection de ladite membrane. On peut ainsi sans changer le moule, par simple mise en place d'une autre membrane de configuration adéquate, réaliser des séries successives d'objets moulés présentant des variantes de formes ou modèles.
