Summary

Summary -- Casting the Universal Joint
Coupler for a Marine Engine in Ductile Iron

The universal joint coupler in the marine engine drive train was converted to a ductile iron casting with a cost savings of 50%, achieved by --

Improved near-net shape which reduced machining operations.
Casting in sand for low cost, high volume, just-in-time production.

Conversion to a casting also reduced inventory costs by offering “Just-In-Time” production lots with shorter lead times and lower shipping costs, compared to the off-shore forging source.
