Dana India Maintenance Engineer Interview Questions and Answers

The mechanism in a hydraulic press is the system of components that allows for the transmission of force through a fluid to generate a large amount of pressure.

• Hydraulic press uses a hydraulic cylinder to generate force.

• The force is transmitted through a fluid, typically oil or water.

• The mechanism includes valves, pumps, and pistons to control the flow of the fluid and generate pressure.

• The pressure created by the mech...read more

Forging is a manufacturing process involving the shaping of metal using localized compressive forces.

• Heating the metal to a high temperature to make it more malleable

• Applying compressive forces to shape the metal into the desired form

• Cooling the forged metal to strengthen it

• Types of forging include open-die forging, closed-die forging, and seamless rolled ring forging
