A Design Study in
Ductile Iron - Dotson Company Pivot Frame
Orientation
and Riser Design
The
foundry engineer uses orientation and risers to produce the desired
directional solidification. For
the pivot frame there are two options for orienting in the mold and placing
the riser (which feeds metal into the casting during solidification).
Option
A -- Hub Down
The hub is positioned
low in the mold with the riser feeding metal into the frame positioned
high in the mold.
Option
B -- Hub Up
The hub is positioned high
in the mold with the riser feeding metal directly into the hub.
Choose
which hub orientation and riser design is best for producing the desired
directional solidification. Hub
Down or
Hub Up
