Centrifugal castings used as forming mandrels
Many composite and sheet metal structures are hot-formed around tooling that is typically a welded fabricated structure. Because of heat in the production process, tools are prone to deformation especially if large components are being produced. This distortion results in tolerance and roundness issues in the finished part. The use of alloys that resist thermal expansion, and the homogeneous nature of centrifugals used in this application eliminate roundness concerns and provide a high quality finished part. Lab testing as well as field performance indicate that a centrifugal casting used in tooling applications can provide five times the tool life of a traditional fabricated assembly.
