Question

Sand Slinger is used for filling and ramming a large core.

(a) True

(b) False

I got this question during an interview for a job.

My doubt stems from Methods of Making Cores in chapter Sand Moulding of Foundry and Forging

Answer 1

The correct choice is (a) True

The explanation: Sand Slinger makes use of a high speed rotating sand impeller which throws the sand in the core box at high velocities. The impact action of the sand stream is responsible for the compacting (or ramming) the core.
