A Design Study in Austempered Ductile Iron - Smith Foundry Drive Wheel

Design B - One Riser on the Hub

A single cylindrical riser will feed metal into the heavier center hub during solidification.

  • The molten metal enters the casting through  two gates on the perimeter of the lower rim.

But this riser will interfere with the center core and  be difficult to cut off from the hub

  • It will leave extensive grinding marks on the hub which will detract from the appearance of the finished wheel.

The single riser on the hub is not the best design.
Go back and select another riser design.
