Question

In cold chamber die casting, rapid cooling of the castings is done as compared to the hot chamber die casting.

(a) True

(b) False

I had been asked this question in an online interview.

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

Answer 1

Correct answer is (b) False

For explanation I would say: In hot chamber die casting, the holding furnace for the liquid metal is integral with the die casting machine, whereas in cold chamber die casting, the metal is melted in separate furnace and then poured into the die casting machine with the help of a ladle for each casting cycle which is also called shot.
