Question

The metal in the feeder head cannot be compensated to the shrinkage as the casting solidifies.

(a) True

(b) False

I got this question in quiz.

I'd like to ask this question from Principles of Gating and Risering topic in section Concept of Gating and Risering of Foundry and Forging

Answer 1

Right choice is (b) False

To elaborate: The molten metal rises in the feeder head after the mold cavity is filled up. This metal in the feeder hear (or riser) always compensates the shrinkage as the casting solidifies.
