Understand sprue, runner and gate design for clean metal flow.
Section 1
Identify the components of a gating system.
Explain how gating controls the speed and cleanliness of metal flow.
Describe how poor gating leads to turbulence and defects.
Relate gate design to fill time and casting quality.
Section 2
The gating system is the network of channels that carries molten metal from the pouring basin into the mould cavity. It usually consists of a pouring basin, a tapered sprue, one or more runners, and ingates that connect to the cavity.
Good gating delivers metal smoothly and at a controlled rate, minimising turbulence that can trap air and oxides.
If the sprue is too wide or the metal falls too fast, the flow becomes turbulent and draws in gas, producing porosity and inclusions. A well-tapered sprue keeps the channel full and the flow laminar.
You will experiment with these parameters directly in the Gating Simulator in a later sprint.
