A Design Study in Steel - ME Elecmetal Crawler Track Shoe

The Casting Design Issues  

NASA selected the ME Elecmetal Company of Duluth, MN to produce the castings.

The casting design team (the ME Elecmetal casting engineers and the NASA design engineers) focused on three imperatives.


--   Design for Performance
--   Design for Production/Castability
--   Design for Cost

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

  • Select a steel alloy  that meets the mechanical requirements and produces this heavy casting in a sound condition.

  • Select a molding method that produces the required surface finish and dimensional tolerances in a cost-effective manner.

  • Develop a casting and mold design that produces flaw-free shoes at the best cost.
