I got this question in my homework.

Origin of the question is Gravity Die Casting in portion Special Casting Techniques of Casting-Forming-Welding I

Answer 1

Correct answer is (b) False

For explanation: Not all materials can be casted easily by gravity die casting essentially because of the mould material. The problem of sticking arises due to the application of metallic mould; so much of lubricant is required, still cannot be suited for every metal. This casting method is applicable to some metals only.
