Solution
Answer: Option A
Solution:
The purpose of a gate is to delivers molten metal into the mould cavity.A proper method of gating system is that it leads the pure molten metal to flow through a ladle to the casting cavity, which ensures proper and smooth filling of the cavity. This depends on the layout of the gating channels too, such as the direction and the position of the runner, sprue and ingates.
