Lightweighting Automotive Castings: Sand vs Die Casting Design Rules in CAD

Shaving Grams from Engine Subframes and Suspension Knuckles

Automotive fuel efficiency and electric vehicle driving ranges depend on aggressive chassis lightweighting. Designing cast aluminum components requires tailoring geometries to specific foundry casting methods.

Sand Casting vs. High-Pressure Die Casting (HPDC)

Matching component geometry to casting processes prevents structural voids and porosity defects.

  • Draft Angles and Parting Lines: Applying 1° to 2° draft on sand castings versus 0.5° on precision steel die tools.
  • Avoiding Hot Spot Sinks: Maintaining uniform wall thicknesses and adding gradual transition fillets to prevent shrink porosity.
  • Core Pull Orientations: Eliminating complex internal sand cores to cut foundry cycle times and tooling costs.
