A method to deliver molten metal from a ladle to a die casting shot sleeve, and a ladle and a shot sleeve assembly are provided. Both the ladle and a rotatable device coupled to the shot sleeve are made to rotate about a respective axis as a way to reduce air entrainment and oxide film inclusions during a gravity filling of the shot sleeve with molten metal from the ladle. In a preferred form, the axis of rotation of the nozzle in the ladle is orthogonal to the axis of rotation of the shot sleeve rotatable device which is preferably placed in a horizontal filling direction. The nozzle is configured to deliver the molten metal through a lowest level of the shot sleeve when the ladle is rotated from a first position to a second position about its axis, followed by its rotation about a filling axis of the shot sleeve from a first angular position to a second angular position. At the second angular position, a die casting plunger fills the casting cavity with the molten metal which has been delivered to the shot sleeve. |
