Abstract

Nouveau procédé d'obtention de pièces moulées, de forme particulièrement complexe, d'épaisseur variable et de haute précision réalisées à partir d'une suspension contenant des fibres dispersées dans une phase liquie, qui se caractérise par le fait que l'élimination de la phase liquide s'effectue principalement dans les zones de hautes précisions desdites pièces, comme par exemple les zones à arêtes vives du moule, les zones en creux, en relief... Ce procédé est particulièrment intéressant pour la réalisation de pieces moulées fibreuses réfractaires de formes complexes.New process for obtaining molded parts, of particularly complex shape, of variable thickness and of high precision, produced from a suspension containing fibers dispersed in a liquid phase, which is characterized by the fact that the elimination of the liquid phase is carried out mainly in the high precision areas of said parts, such as for example the areas with sharp edges of the mold, the hollow areas, in relief ... This process is particularly interesting for the production of refractory fibrous molded parts of complex shapes.
