What is choke area?

Choke area is the main control area which meters the metal flow into the mould cavity, so that the mould is completely filled within the calculated pouring time. Normally, the choke area happens to be at the bottom of the sprue and hence, the first element to be designed in the gating system is the sprue size and its proportions. The main advantage in having sprue bottom as the choke area is that proper flow characteristics are established early in the mould.
