Vertical Centrifugal Casting

What is vertical centrifugal casting? This video shows what happens during the centrifugal casting process. High g-forces applied to the molten metal in the spinning die move the less dense material, including impurities, to the I.D. where it is subsequently removed by machining.

How much of the ID is imperfections? Is the OD case hardened during this process?

I wonder the RPM's required

[@mohamedahmed-ts1cr]

the mold is rotated at a speed that creates a centrifugal force ranging from 75 to 120 g
(75 to 120 times the force of gravity). Speed of rotation is varied during the casting process
