Abstract
A casting die includes a first ingate defining a first annular chamber and a second ingate defining a second annular chamber and spaced from the first ingate. The die includes a first end ring gate concentric with the first ingate and defining a first end ring chamber in fluid communication with the first annular chamber, and a second end ring gate concentric with the second ingate and defining a second end ring chamber in fluid communication with the second annular chamber. The die includes runners interconnecting the first and second end ring gates. Each of the runners defines a conductor bar channel in fluid communication with the first and second end ring chambers. The die includes an overflow gate disposed between the first and second ingates, wherein the overflow gate defines an annular overflow chamber in fluid communication with the conductor.
