Question

A core is a disposable item but it can be reused from time to time.

(a) True

(b) False

I have been asked this question by my college director while I was bunking the class.

My query is from Cores and Core Prints in section Foundry Introduction of Foundry and Forging

Answer 1

The correct answer is (b) False

Easy explanation: A core is a device which is normally made up of sand. The technology of metallic cores is emerging in manufacturing technology. The core when used once usually comes out in the burnt form and hence even though it is disposable, it cannot be reused.
