An Example in Steel Casting    Traction Motor Rotor Disc

Gating System Design

The gating system (downsprues, runners, and gates) serves as the flow path for molten metal into the mold cavity. Proper design of the gating system is critical to provide for uniform, controlled metal flow

Non-uniform, long path, and/or slow metal flow may produce unfilled sections or solidification shrinkage in the casting.

Too many gates and runners will also require additional molten metal and decrease the casting yield (metal in casting versus total metal poured)
