Question

The core boxes are provided with wires perform a function of which of the following component?

(a) Riser

(b) Gates

(c) Vents

(d) Shell

I have been asked this question during an interview.

Query is from Methods of Making Cores topic in section Sand Moulding of Foundry and Forging

Answer 1

Right answer is (c) Vents

Explanation: The incoming air in the core blowing machine with the sand is exhausted through the vents provided in the core-box. The wires in the core boxes automatically provide vent holes in the cores as they are blown off. They are withdrawn before the core is stripped.
