Centrifugal casting is a method that uses centrifugal force to distribute molten metal into rotating molds. There are three main types: true centrifugal casting produces hollow cylindrical parts like pipes by pouring metal into a horizontally or vertically rotating mold; semicentrifugal casting makes parts with rotational symmetry like wheels with spokes; and centrifuging forces molten metal from the center into stationary molds placed around the axis of rotation. Centrifugal casting results in dense, high quality castings with variations in properties depending on their distance from the center of rotation.
