Design A - Two Risers on the Rim
The two cone-shaped risers on the sides of the wheel will feed metal into the rims, the spokes, and the center hub during solidification.
The molten metal is gated into the two risers which feed into the rims of the casting.
The risers will also act as heat reservoirs to keep the rim and spokes molten as the center hub solidifies.
The risers can also be easily cut from the rim, with reduced grinding and finishing at the cut-off points.
The two risers on the rim are the best design. Go to the Next Design Issue!
