Question

Overflows should be avoided as much as possible in the designing of a die.

(a) True

(b) False

This question was posed to me in an online interview.

This interesting question is from Vacuum Die Casting topic in section Special Casting Techniques of Casting-Forming-Welding I

Answer 1

Correct option is (a) True

Best explanation: Overflows are provided in the parting plane for the first metal which is usually cold, enters in the die cavity, to solidify. The overflow is a luxury and cannot be acceptable in every casting, so it should be avoided as much as possible in the designing of the die. It is primarily provided for small components only.
