Question

_________ machines are used for shallow patterns.

(a) Core making machine

(b) Sand Slinger machine

(c) Squeeze machine

(d) Jolt machine

This question was addressed to me by my college professor while I was bunking the class.

The doubt is from Moulding Machines topic in section Moulding Machines & Special Moulding Processes of Foundry and Forging

Answer 1

The correct option is (c) Squeeze machine

For explanation: A squeezer, squeeze head plate or presser board slides inside the flask to compress the sand above and around the pattern. The presser plate exerts a substantial amount of pressure. The pressure can be easily distributed for the shallow patterns in a squeeze machine.
