Abstract

L'invention concerne un procédé de compactage rapide de matières particulaires afin de former une pièce. Ce procédé comporte les étapes consistant à : fournir une cavité au moins partiellement formée par au moins un poinçon inférieur ; insérer dans cette cavité une préforme comprenant au moins deux niveaux ; et à déplacer rapidement un piston principal commandé énergétiquement en direction de la préforme pour accroître la densité de la préforme et former ladite pièce. L'invention se rapporte en outre à une pièce à niveaux multiples constituée de matière particulaire ainsi qu'à une presse de compactage.
