Question

Better surface finish with the close dimensional tolerances of the casting can be obtained in gravity die casting.

(a) True

(b) False

I had been asked this question in examination.

I would like to ask this question from Gravity Die Casting in section Special Casting Techniques of Casting-Forming-Welding I

Answer 1

Right answer is (a) True

The best I can explain: In gravity die casting, a fined-grained casting with good surface finish of the order of 4 microns can be produced. Close dimensional tolerances can also be obtained and with a better appearance of the casting. It is also economical for large scale production as the labour involved in the mould preparation is reduced.
