Dimensions and shapes

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 toolings (more than 1500 dies) enables us to reach the ideal cast sizes and shapes, consequently to propose the most economical solutions.


Minimum Maximum
Outer Ø Lenght Outer Ø Lenght
Short Horizontal centrifugal casting (or spun casting) 60 150 850 1,000
Long Horizontal centrifugal casting (or spun casting) 200 1,000 1,000 4,500
Vertical centrifugal casting (or spun casting) 300 200 6,000 2,500

Minimum weight = 1 Kg - Maximum weight = 22 tons
The inside diameter is defined by the quantity of centrifugally cast (or spuncast) alloy.
