Abstract

Le présent document porte sur un procédé de fabrication d’une pièce métallique, à partir d’une ébauche d’une pièce disposée sur un support mécanique et comprenant au moins une partie fonctionnelle et au moins une partie non fonctionnelle, le support mécanique et l’ébauche étant réalisés à partir d’un premier mélange de premières particules métalliques et de deuxièmes particules de liant, le procédé comprenant les étapes suivantes : a) obtenir un premier ensemble en introduisant au moins un insert à travers ladite au moins une partie non fonctionnelle de l’ébauche et au moins en partie à l’intérieur du support pour fixer l’ébauche sur ledit support ; b) fritter le premier ensemble de manière à obtenir une pièce intermédiaire ; c) obtenir la pièce finale en séparant la partie fonctionnelle de la pièce intermédiaire de la partie non fonctionnelle.
