Question

Shrinkage allowance does not depend on which of the following factor?

(a) Moulding method

(b) Casting dimension

This question was addressed to me during an internship interview.

Question is taken from Pattern Allowances topic in chapter Preventive Maintenance in Foundries & Metal Casting Process of Casting-Forming-Welding I

Answer 1

Right answer is (d) Amount of finish required

The explanation: Shrinkage allowance does not depend on the amount of finish required. The amount of finish needed on the machining portion is a factor on which Machining allowance depends. Shrinkage allowance depends on all other remaining factors.
