Question

Which of the following is not an example of the top gate?

(a) Finger gate

(b) Wedge gate

(c) Horn gate

(d) Ring gate

This question was addressed to me in quiz.

Enquiry is from Types of Gates in section Concept of Gating and Risering of Foundry and Forging

Answer 1

The correct choice is (c) Horn gate

The best I can explain: Top gate is the one in which the molten metal always drops to the bottom of the mould. Hence, finger gate, wedge gate and a ring gate perform such function whereas the horn gate is a bottom gate.
