Abstract

L'invention concerne une machine pour la production de composants moulés en un matériau pouvant être rendu compact. Selon l'invention, la machine comprend une plaque de matrice 10 ayant au moins une cavité 12: un ensemble de filtrage 22 pouvant former un organe de fermeture de la cavité d'un côte de la plaque; une plaque de couverture 24 pouvant être amenée en engagement avec le côté opposé de la plaque de matrice ; et un moyen 62, 64, 66 pour amener une boue pouvant être tassée à la cavité et un moyen 54 pour y maintenir la pression de la boue de façon que le liquide soit expulsé à travers l'ensemble de filtrage pour produire un matériau compact à une condition requise dans la cavité L'invention s'applique notamment à la préparation d'aimants permanents.
