• Material solutions are often sought to aid n meet- eighting automo-
tive components. Counterintuitive to the norm, an aluminum component was co
to reduce weight by 25% while also reducing cost. • To relieve a supply chain disruption involving Ford Motor Co.’s high volume CD4 platform, the car- maker worked with Waupaca Foundry and Hitachi Metals to produce the high strength, lightweight cast iron suspension component.

• Design optimization tools helped revise and verify design concepts to produce a control arm that fi t the allowable packaging space, met strength and durability requirements and reduced weight. De- spite a compressed schedule and expedited tooling manufacture, the production launch moved forward without any signifi cant issues or delays.
