(a) True

(b) False

This question was addressed to me during an online exam.

My doubt stems from Riser Design in portion Pattern and Mould, Principles of Gating & Risering of Casting-Forming-Welding I

Best answer
Right choice is (b) False

The best explanation: Feeding distance is more implies molten metal can flow for a longer distance. This will result in very few mushy zones in the casting. Hence, if the mushy zone is less, the number of risers required will also be less.
