The centrifugal casting process is an industrial production process done by fusion. The liquefied material (metal, plastic) is conveyed into a permanent tubular form, called “mold”, with an externally induced pressure.
The centrifugal force, determined by the rotation on the vertical or horizontal axis of the mold, allows a uniform filling, making the casting material adhere to the internal walls of the mold. By dosing the material appropriately, the finished piece develops a cavity along the rotation axis of the mold.
The semi-finished product is removed from the mold after its solidification.
The molds used can be “disposable” (made in sand for the production of few pieces) or permanent (in steel, copper, graphite).
Some examples of products obtained by centrifugal casting are engine components, cylinder liners, piston segments, pipes and flanges, continuous casting rollers.
