Step 1:  Molten Alloy is poured into a spinning die which can be spinning

vertically or horizontally depending upon part configuration.


Step 2:  The spinning forces the heavier metal to the outside due to centrifugal force; while impurities and oxides are forced to the ID.


Step 3:  The metal solidifies from the outside in, leaving no mid-wall shrinkage.

Step 4:  Impurities in the center bore are then machined away leaving a defect free structure without shrinkage cavities or gas pockets.

Centrifugal castings offer the designer, engineer or purchaser several advantages that set it apart from alternate processes.


      Improved Grain Structure:  Due to centrifugal forces and directional solidification; parts produced by the centrifugal casting      

      process exhibit a denser, more uniform equiaxed grain structure.


      Improved Physical Properties:   Because of high structural uniformity and improved grain structures; physical properties such   

      as tensile strength, yield strength, elongation, reduction of area, fatigue strength, rupture strain and other desired mechanical      

      properties are markedly improved.


      Elimination of Pattern Expense:  Centrifugal castings are produced by a vast inventory of dies, eliminating the use of patterns   

      customary in sand castings.  Unless a die is not available (in extreme cases) or other special cases, the cost of tooling or    

      patterns is eliminated.


      Defect Free Technology:  Due to centrifugal forces and directional solidification; parts exhibit defect free structures whereas

      NDE such as Radiographic Testing may be deemed unnecessary.


      Reliable Service:  Due to defect free structures, improved grain structures, etc. Centrifugal castings provide more reliable

      service life and withstand increased environmental conditions (i.e. higher service temperatures, corrosive environments and   

      stresses) without failure.


      Lower Lifetime Costs:  Due to improved physical properties and greater reliability, Centrifugal castings often are lower in cost

      over the life of the part.
