A runner is a channel in a precision casting gating system that distributes molten metal from the sprue to multiple gates.
In precision casting, particularly investment casting, the runner is a critical component of the gating system. It serves as the primary distribution network that channels molten metal from the central sprue to individual gates leading into mold cavities. Runners are designed to maintain proper metal flow, temperature control, and pressure distribution to ensure complete cavity filling and minimize defects like cold shuts or misruns. They are typically part of the wax pattern assembly that is invested in ceramic shell before casting.

The runner distributes molten metal from the sprue to multiple gates, ensuring even filling of mold cavities and controlling flow dynamics.
Runner size is based on casting volume, metal properties, and gating design principles to maintain proper flow velocity and thermal conditions.
In investment casting, runners are part of the one-time wax pattern and are not reused; in other processes, they may be remelted.
