Abstract

L'invention concerne la production de composants, de préférence d'une turbine à gaz, en particulier d'un propulseur d'avion, ce procédé faisant appel au moulage par injection de poudre métallique. Lors du moulage par injection de poudre métallique, on mélange d'abord une poudre métallique avec un liant de façon à obtenir une masse homogène, et ensuite on réalise, par moulage par injection de cette masse homogène, au moins un corps moulé, le ou chaque corps moulé étant alors soumis à un processus de déliantage. Enfin, le ou chaque corps moulé est comprimé par frittage pour former au moins un composant présentant les caractéristiques géométriques voulues. Selon l'invention, lors du frittage, le ou chaque corps moulé est placé dans au moins un dispositif de support qui est également rétractable pendant le frittage. L'invention concerne en outre un dispositif de support correspondant.
