A method for manufacturing a railcar coupler knuckle includes providing a first mold section having internal walls defining at least in part perimeter boundaries of a first coupler knuckle mold cavity. The method includes providing a second mold section having internal walls defining at least in part perimeter boundaries of a second coupler knuckle mold cavity. The second coupler mold cavity of the second mold section is offset from the first coupler mold cavity of the first mold section. The method includes closing the first and second mold sections and at least partially filling the first and second coupler knuckle mold cavities with a molten alloy, the molten alloy solidifying after filling to form the coupler knuckle.

Linvention concerne un procédé de fabrication dune mâchoire dattelage de véhicule de chemin de fer consistant à utiliser une première section de moule présentant des parois internes définissant au moins en partie les limites du périmètre dune première cavité de moule de mâchoire dattelage. Le procédé consiste à fournir une seconde section de moule présentant des parois internes définissant au moins en partie les limites du périmètre dune seconde cavité de moule de mâchoire dattelage. La seconde cavité de moule dattelage est décalée de la première cavité de moule dattelage de la première section de moule. Le procédé consiste en outre à fermer les première et seconde sections de moule et à remplir au moins partiellement les première et seconde cavités de moule de mâchoire dattelage dun alliage fondu, lalliage fondu se solidifiant après le remplissage de manière à former la mâchoire dattelage.
