An Example in Steel CastingTraction Motor Rotor Disc
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
