Max outer diameter

The centrifugal casting process (or spun casting) is mainly suitable for cylindrical or hollow pieces (rings, tubes etc…). Conical shapes, several different diameters or flange(s) can be obtained on the “as cast” outer profile.
As we do not use cores, the inside diameter is cylindrical and is achieved by the quantity of liquid metal poured into the tooling.

Our extensive range of tooling (more than 1500 dies) enables us to reach the ideal cast sizes and shapes, consequently to propose the most economical solutions.
