Abstract

Des pièces profilées sont réalisées à partir d'une poudre possédant les propriétés chimiques nécessaires à la pièce finie en mélangeant ladite poudre avec une résine de condensation thermodurcissable servant comme liant. Ladite résine peut être partiellement catalysée, ou des additifs ou des surfactants peuvent être ajoutés de manière à améliorer la rhéologie, les propriétés de mélange, ou la durée du traitement. Lors de la caléfaction, le mélange à viscosité faible inhérente se solidifie sans que l'on lui appliqueune pression. Une forme rigide susceptible d'être démoulée d'un moule est obtenue. On réalise des formes préfrittées par un moulage par injection, utilisant un outillage semipermanent, ou en créant un prototype. Des moyens thermiques assurent l'enlèvement du liant sans faire appel à une étape séparée de décollage, malgré la résistance à la chaleur connue des résines thermodurcissables. Ledit enlèvement est possible grâce à la caractéristique du liant lui permettant de réaliser une feuille mince qui laisse ouverts les pores de la pièce. Des conditions propres à l'oxydation dans lesdits pores lors de la caléfaction de la pièce sont ainsi créées et on assure la diffusion, à travers les pores, de la vapeur provenant de la résine qui se dévelope à travers les pores lorsque la pièce est chauffée sous vide.
