The transmission case
is cast with the barrel in a vertical orientation. The mold has two down sprues which feed
into runners and ingates. The ingates must provide sufficient metal flow without excessive
velocity or turbulence.
>> Multiple gates are required to provide
complete flow into thin walls.Two different gating designs were considered and are shown in the drawing to
the right --
- Option A - Three gates on each side.
- Option B
- Five gates on each side.
Choose
the gating system
(Option A
or Option B )
which provides the best metal flow into
the thin walls. |
