Abstract
A gating system for vertical die casting of a squirrel cage rotor includes an upper end ring cavity, a lower end ring cavity, and a plurality of passages in fluid communication with the upper and lower end ring cavities for forming rotor bars. A gate is radially distanced from the passages, and molten metal is injected into the lower end ring cavity and fills the lower end cavity before filling the passages. The passages are therefore filled at approximately the same time and rate until the passages are full and the upper end ring cavity fills with molten metal.
