Abstract

L'invention concerne des procédés perfectionnés de séchage, de vaporisation de liant et de frittage pouvant être utilisés conjointement avec des outils de frittage spécialisés pour permettre un frittage géométriquement stable de composants ou de corps d'écoulement de préformage, complexes et de grandes dimensions, obtenus par moulage par injection de poudres métalliques. Le procédé amélioré comprend un processus de séchage en trois étapes, un processus de vaporisation du liant en une étape et un processus de frittage en deux étapes.
