Centrifugal casting

Why centrifugal castings

Centrifugal casting process

In centrifugal casting the melted metal is poured into a fast rotating metal mould. As poured, the metal is forced by the centrifugal force against the mould walls. The generated pressure assures tight contact between the metal and the mould. Gases and intrusions are conveyed towards the centre of rotation, onto the inner section of the casting which is removed by the following machining. The casting gradually solidifies in the direction from the wall towards the axis of rotation. The remaining melted metal is pushed into casting cavities and this improves casting homogeneity.

Benefits of centrifugal castings

The high quality of centrifugal castings predetermines them for employment in heavy duty conditions.

Centrifugal casting has a homogeneous, fine-grained structure, without impurities or intrusions. Its mechanical properties are 30 % better than gravity castings.

Typical examples of centrifugal casting uses

Centrifugal castings are used as: sliding bearings, half bearings, bushes, worm gears, screw nuts, shaft liners, slip rings, sealing rings, balancing rings, bearing cages.
