Abstract
A mold for casting a vehicle wheel includes a movable top core which cooperates with a base member to define a mold cavity. The mold also includes a plurality of movable segments mounted upon the top core. The movable segments define a central gate which communicates with the mold cavity. The central gate receives a charge of molten metal and feeds the charge into the mold cavity. A porous filter is disposed within the gate.
