Unique Geometries
Unique geometries are usually poured using the vertical centrifugal method. Vertical centrifugal casting machinery spins parts about a vertical axis. Parts are commonly of shorter hieght than diameter. The great benefit of spinning about a vertical axis is that practically any size and shape of casting can be spun about a vertical axis. Common non-traditional castings poured in vertical machinery are ball valve balls, conicals and propellors.

We are often asked if a casting that is commonly poured statically be poured vertically, even if it is a non tubular shape. The answer is yes. With detailed attention to mold design, these castings can benefit from the added spin. Why pour castings in a vertical spinning machine that can be poured statically? The primary reasons are to obtain better quality castings, to produce castings more economically and to cast a part that cannot be satisfactorily cast statically. Reduction in cleaning room costs and higher yield are common reasons why foundries pour castings using vertical centrifugal casting machinery. Steel castings that are statically poured with a yield of 40 to 55% can be centrifugally cast with a yield closer to between 65 and 85%.
