(b) False

I got this question in examination.

This intriguing question originated from Methods of Making Cores topic in chapter Sand Moulding of Foundry and Forging

Answer 1

Correct choice is (a) True

Easiest explanation: Core blowing machine makes use of compressed air (at 5 to 7 kg/cm² pressure) to blow the sand into the core box at high velocity. Thus, the filling and ramming of the core are done.
