Abstract

La présente invention concerne un procédé de fabrication d'une cale de friction d'un wagon qui comprend la formation, dans des parties de traîne et de face d'un moule, d'au moins une cavité qui définit au moins certains éléments extérieurs d'au moins une cale de friction. Au moins un noyau est inséré dans la partie de traîne adjacente à la cavité. Le noyau comprend au moins une surface configurée pour définir une face de colonne de la cale de friction. Un support est formé dans la partie de traîne et de face du moule. Le support comprend au moins une descente, au moins une attaque, et au moins un canal pour diriger le matériau fondu vers la cavité. Le matériau fondu est versé dans le moule pour former la pièce de cale de friction. La pièce de cale de friction est retirée du moule. Le support est enlevé de la pièce de cale de friction et la pièce de cale de friction est finie.
