Design Issues

The Casting Design Issues

Spokane Industries Steel Casting Division worked closely with P&H Mining to design and produce the snubber arm castings.

The casting design team (the P&H Mining design engineers and the Spokane Industries casting 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 reliably produces the casting in a sound condition.
Select a molding method that produces the required dimensional tolerances and surface finish in a cost-effective manner.
Develop a casting and mold design that produces flaw-free components at with an optimized production cost.
