A Design Study in Ductile Iron - Dotson Company Pivot Frame

Benefits of Casting with Ductile Iron

The direct benefits of casting the pivot frame in ductile iron in green sand are --
  • Cost Savings -- The new casting produced a 50% cost savings on each part, compared to the original costs of assembly, welding, and machining. The tool pay-back was 4 months of production.

  • Performance Benefits -- Better form and fit with less dimensional variation compared to the weldment. Lower stresses and longer life with the casting design.

  • Manufacturing Benefits -- One piece design reduces part inventory, technical data management costs, and production-delivery time.
