Vertical centrifugal casting machinery spins parts about a vertical axis. Parts are commonly of shorter height 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 castings poured in vertical machinery are rings and ball valve balls. Generally, vertical machines are divided into two categories, Stand-Alone machines, which can be easily added into a foundry with limited foundation work and Pit Mounted machinery, which are mounted below floor level and require a foundry to do substantial foundation work.
The question commonly asked is, can a casting that is commonly poured statically be poured vertically, even if it is a nonstandard shape. The answer is yes. 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%.
