Sand Casting

Sand casting involves the process of using a mold made by pressing a pattern into a sand mixture and molten metal is then poured into the pattern created.

PolyJet or FDM patterns can best replace the traditional method when

  • Casting designs need verification
  • Gate and runner refinements are likely
  • Castings will be complex or large

Benefits of PolyJet and FDM patterns for sand casting include:

  • Pattern cost reduction of 50 to 70 percent
  • Lead-time reduction of 30 to 70 percent
  • Faster design revisions
  • Interchangeable gate and runner system
