What is the maximum pressure required to be given in a squeezing process?(a) 6.5 kg(f)/cm^2(b) 7.5 kg(f)/cm^2(c) 8.5 kg(f)/cm^2(d) 9.5 kg(f)/cm^2The question was posed to me in a job interview.The question is from Molding Machines in portion Foundry Mechanizations of Casting-Forming-Welding I

Answer» CORRECT option is (b) 7.5 kg(f)/cm^2

Explanation: A molding force is applied with the help of a piston in squeezing machines. This CAUSES the AIR to get pressurized. This minimum PRESSURE of the air can be 6 kg(f)/cm^2 and the MAXIMUM air pressure can be 7.5 kg(f)/cm^2.
