(c) Greater

(d) Negligible

I had been asked this question during an internship interview.

I'm obligated to ask this question of Gravity Die Casting in section Moulding Machines & Special Moulding Processes of Foundry and Forging

Answer 1

Correct choice is (c) Greater

To elaborate: The greater thickness of the mold walls can remove greater amounts of heat from the casting, they that is the mould walls are made thicker opposite thicker sections of the castings. This provides a desirable chilling effect.
