Option B --
Gating into
the Foot of the Lever Arm |
| In Option B,
one narrow gate feeds into the foot of the lever arm. This gating approach is
not preferred because:
|
|
|
-
The metal
feeds into the far end of the casting and has a long run into the opposite end,
risking misruns and unfilled sections.
-
The
narrow gate will produce faster, more turbulent metal flow
-
The
center section will be isolated from the gate and may solidify
without adequate liquid metal feed, risking solidification
shrinkage.
