The Johnson Centrifugal Technology Process

Vertical Centrifugal Castings

The vertical centrifugal castings process introduces liquid metal into a rapidly rotating die.  The metal experiences a heavy G load causing it to climb the walls and take shape of the die.  During this process the liquid metal is under such a heavy G load that air bubbles cannot exist and the metal freezes in the shape of the die. This process of casting guarantees the highest quality metal components.

By solidifying uniformly under high pressure, centrifugal castings combine the chemical and mechanical property capability of forgings with the cost efficiency of traditional castings.
