Question

What is the maximum pressure, which can be applied in a pressure die casting?

(a) 4530 kg/cm^2

(b) 4980 kg/cm^2

(c) 5000 kg/cm^2

(d) 5100 kg/cm^2

The question was posed to me in final exam.

The above asked question is from Hot Chamber and Cold Chamber Die Casting topic in division Preventive Maintenance in Foundries & Metal Casting Process of Casting-Forming-Welding I

Answer 1

Correct choice is (c) 5000 kg/cm^2

Easiest explanation: The maximum pressure, which can be applied in a pressure die casting is 5000 kg/cm^2. For some castings, with lesser hardness, the maximum pressure limit is lesser. If the magnitude of pressure applied exceeds the value of 5000kg/cm^2, then the cast may get damaged.
