What this NAICS covers

NAICS 331523 covers facilities that produce metal parts by forcing molten nonferrous alloys into reusable steel molds to form precision die-cast components, including subsequent trimming, defect removal, and basic surface finishing for delivered castings.

Federal opportunities under 331523 typically involve supplying series production die-cast parts to specification drawings, meeting dimensional tolerances, specified alloy chemistry, porosity limits, and delivery as raw castings or with standard machining and surface treatments.

FAQ

What work fits NAICS 331523?
  • Producing production runs of aluminum die-cast housings to drawing tolerances and specified alloy chemistry.
  • Manufacturing high-volume zinc die-cast brackets and mounts with trimming, shot-blast, and basic machining per purchase specifications.
  • Supplying magnesium die-cast structural components with porosity control and delivered inspection reports.
  • Delivering prototype and low-volume die-cast runs for qualification builds, including trial casting samples and inspection data.
When is NAICS 331523 a weak fit?
  • Sand casting or investment casting shops: use different casting processes and do not use high-pressure die-casting molds, so molten-metal high-pressure injection is missing.
  • Aluminum extrusion manufacturers: missing the molten-metal die-casting process and reusable die cavities; extrusion forms profiles rather than die-cast components.
  • Metal stamping and sheet-metal fabrication: missing the die-casting molten-metal molding process and associated gating, shot, and die operations.
What solicitation language points to NAICS 331523?
  • Specifications call out high-pressure die-casting process parameters, shot weight, cavity count, and a named alloy or alloy specification.
  • Deliverables require casting inspection reports, porosity acceptance criteria, dimensional CMM reports, and material chemistry certification.
  • Quality requirements list heat treatment, tensile or hardness test results, and metallurgical acceptance criteria tied to castings.
