Abstract

La présente invention concerne un procédé de frittage d'une pièce frittable, caractérisé par le fait que l'on contrôle l'évolution dimensionnelle de la pièce et que l'on arrête le frittage à au moins une dimension de la pièce qui est la dimension finale correspondante voulue à froid plus la dilatation thermique calculée pendant la phase de montée en température avant le début du retrait.
