Question

The entrapment of gas is negligible in the squeeze casting method that results in lower shrinkage cavities in the castings.

(a) True

(b) False

This question was addressed to me in an internship interview.

My doubt is from Casting Techniques topic in portion Casting Process of Casting-Forming-Welding II

Answer 1

Right answer is (a) True

Easy explanation: The squeeze casting technique almost has negligible gas entrapment which results in less shrinkage cavities and good quality of surface with fine details on the casting parts. Aluminum and copper alloys are widely manufactured by this technique. It also produces the fine grain size to enhance the properties of the castings.
