Centrifugal castings = Babbitt bearings


Centrifugal castings are made when a mold is continuously rotated at high speed while molten metal is poured in. The molten metal in a centrifugal casting is thrown toward the inside of the mold wall from the G forces inside. The molten metal solidifies after cooling.  After cooling, any impurities can be machined away that […]

The process takes into consideration what exists, for example a motor or mechanical component, and through analysis determines how to duplicate or enhance that item. Reverse engineering can design improvements on the structure, operation and performance of one specific item, or a system of related parts. […]
