The Casting Design Approach -- The  casting design engineers at the Eck Industries chose gravity casting with "no-bake" sand molds and cores. The engineers had three imperatives for an integrated casting design.

--   Design for Performance
--   Design for Castability/Manufacturability
--   Design for Cost

Critical Casting Design Issues --The requirements for performance, castability/manufacturability , and cost are closely interconnected. Four casting design issues played a major role in meeting the three design imperatives

  • Develop the mold design to optimize metal flow and insure soundness

  • Design the gating system to produce sound castings and maximize casting metal yield.

  • Develop a cost-effective machining process for the transmission case.
