Metal
Flow into the Mold The gating system (sprues, runners, and gates) provides paths for the molten
metal to flow into the mold. For steel castings, it is important that the mold fills
quickly, without turbulent flow.
- Runners and gates have to promote high volume, low velocity
flow.
- On the ice cleat, the logical location for the gate is directly into the thickest
section of the cleat.
- The size of the ice cleat is small enough that multiple items can be produced in
one pouring by putting several ice cleat patterns on a "tree" with the
gates connecting into a single runner.
The runners and gates need to be integrated with the placement of
the risers. |
