Radial distributor for centrifugal casting

An unexpected problem during the centrifugal casting of dental alloys was the optimal shape of the graphite distributor. Taking into account the gravitational and radial-progressive centrifugal force inside the distributor, an analytical shape for internal evacuation channels was calculated.

If the analytical shape is not respected, molten material rest and solidifies inside the distributor, eventually obtruding the evacuation channels. On the other hand, the solidified materials inside the distributor need supplementary labour for removing operations and represent a waste of material.
