(a) High maintenance

(b) Costly machinery

(c) Complex dies

(d) All of the mentioned

I had been asked this question in an interview for job.

The doubt is from Pressure Die Casting topic in chapter Moulding Machines & Special Moulding Processes of Foundry and Forging

Answer 1

Correct option is (d) All of the mentioned

To explain: The pressure die casting process is used only for the processes which require tight tolerances and detailed geometry. For making such dies, the economical aspect is very high and the maintenance of these machines is equally large. Hence they are used only for high-end production.
