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.
