(a) Material loss

(b) Time consuming

(c) Much labour work

(d) Uneconomical for small scale production

The question was asked during an interview for a job.

This interesting question is from Advantages and Disadvantages of Casting in chapter Casting Process of Casting-Forming-Welding II

Answer 1

Correct answer is (d) Uneconomical for small scale production

The best explanation: Low-pressure die casting technique is not economical for small-scale production because the machines used in the processes are very expensive, the parts like riser tube and the device used for compressing the gas makes this method very expensive. So this method is only economical when it is used for large scale productions.
