| 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.  |
