Metal Crown, Closure, and Other Metal Stamping (except Automotive)

NAICS 332119 · Fabricated Metal Product Manufacturing · SBA size standard: 500 employees

Metal stamping shops produce custom and repeat-run crowns, closures, lids, brackets, clips and small formed parts from coil or sheet metal. For a shop that takes customer drawings or specifications and runs both production orders and quick-turn prototypes, the specialists turn incoming orders into job packets with drawings and tolerances, job packets into die and press schedules, schedules into material orders and tooling lists, and completed runs into inspection reports, certifications and invoices. Tooling maintenance, press tonnage limits and first-article approvals stay with the machinist and operator.

Workflows

Order and drawing intake

Starts when: A customer sends an order, drawing, specification sheet or request for quote by email or portal

  1. Capture part number, drawing revision, quantity, due date, material grade and finishing requirements
  2. Verify drawing legibility and completeness against standard tolerances
  3. Check against existing tooling or dies on hand
  4. Draft acknowledgment and lead-time confirmation
  5. Create a job packet with all customer documents attached

Watch for: Tolerances and critical dimensions must be flagged exactly as drawn; Any missing information or unclear callouts must be clarified before production

Press scheduling and die setup

Starts when: After order acknowledgment and on a weekly cadence

  1. Group jobs by material type, gauge, press tonnage and die requirements
  2. Calculate total press time including changeover and first-article approval
  3. Assign to available presses and operators
  4. Flag jobs needing new die design or refurbishment
  5. Produce a daily setup sheet with coil specifications and run quantities

Watch for: Press bed size and tonnage limits cannot be exceeded; Changeover time varies significantly by die complexity

Material and tooling procurement

Starts when: After scheduling and when inventory drops below reorder point

  1. Explode job requirements into coil and sheet quantities by gauge and grade
  2. Subtract current inventory and open receipts
  3. Draft purchase orders for coil, sheet, tooling steel or die components
  4. Track lot numbers and material documentation
  5. Monitor scrap and yield to adjust future orders

Watch for: Certain alloys and tempers have long lead times; Material must be ordered in mill-standard widths to minimize waste

Production execution and first-article approval

Starts when: Start of each scheduled job

  1. Generate setup checklist and safety instructions for the operator
  2. Record first-article measurements and photos
  3. Track run quantities, downtime and scrap
  4. Flag any deviation from drawing tolerances
  5. Release job for full production only after approval

Watch for: First-article parts must be checked by the owner or quality lead; Any tool or die issue requires immediate stop and documentation

In-process and final inspection

Starts when: During and at completion of each production run

  1. Create inspection checklist keyed to critical dimensions on the drawing
  2. Record measurements from calipers, micrometers or CMM
  3. Compare results against customer tolerances
  4. Generate inspection report and certificate of conformance
  5. Tag and segregate any nonconforming parts

Watch for: All inspection data must be traceable to the material lot; Sampling plans follow the owner's defined requirements

Shipping, documentation and invoicing

Starts when: After final inspection approval

  1. Prepare packing list with part count, lot numbers and documentation
  2. Compile all required material and process documents
  3. Schedule carrier pickup or prepare for customer collection
  4. Close the job in the schedule and update inventory
  5. Draft the invoice with quantities, pricing and terms

Watch for: Some parts require special rust-preventive packaging or pallets; Material and process documentation must travel with the shipment

Tooling maintenance and die tracking

Starts when: After each run and on a preventive schedule

  1. Log die usage, strokes and wear measurements
  2. Create maintenance task for sharpening, polishing or repair
  3. Track location and storage of each die set
  4. Forecast when dies will need replacement based on historical wear
  5. Update tooling inventory list

Watch for: Dies are expensive and must be protected from damage; Preventive maintenance schedule is set by the owner based on part complexity
