Metal Can Manufacturing

NAICS 332431 · Fabricated Metal Product Manufacturing · SBA size standard: 1,500 employees

Metal can plants convert rolled steel or aluminum coil into formed, seamed and coated cans for food, beverage, aerosol and industrial use. The specialists convert customer specifications into production orders, coil and coating requirements into a rolling schedule, line changeovers into sequenced runs, and finished pallets into shipments while maintaining coating, seam and pressure-test records the line operators confirm.

What makes this business different

  • Customer-specific can dimensions, metal gauge, interior coatings, exterior lithography and end styles that must match exact specifications
  • High-speed continuous production lines that run dedicated sizes for days or weeks before changeover
  • Coil and lacquer inventory managed by weight and square footage with tight just-in-time replenishment
  • Frequent tooling and line changeovers requiring precise sequencing to minimize downtime
  • Regulatory paperwork for food-contact coatings, seam integrity, pressure testing and lot traceability
  • Palletized finished goods staged for truckload or less-than-truckload shipment with specific labeling
  • Maintenance logs, downtime tracking and scrap rates that affect metal yield calculations

Workflows

Order intake and specification review

Starts when: A customer submits a purchase order or specification sheet

  1. Extract can type, dimensions, metal type, gauge, coating requirements, lithography and end style
  2. Compare against current line capabilities and open capacity
  3. Confirm metal coil and coating availability against current inventory
  4. Calculate required coil weight and draft a production order
  5. Send specification confirmation for customer approval

Watch for: Food-contact coatings must match exact FDA-listed formulations the owner confirms; Any deviation in gauge or coating requires engineering sign-off before acceptance

Production line scheduling and changeover sequencing

Starts when: Weekly or when new orders are confirmed

  1. Aggregate orders by can diameter, height, coating type and end style
  2. Sequence runs to minimize tooling and coating changeovers
  3. Calculate required coil footage and coating volume per run
  4. Assign run dates and line numbers with estimated changeover times
  5. Flag any orders needing special tooling or test protocols

Watch for: Line speed and changeover time vary significantly by can size and coating; Coil splicing and coating batch continuity must be preserved across shifts

Coil and coating material planning

Starts when: After production schedule is locked and on a weekly cadence

  1. Explode scheduled production into coil weight and square footage by alloy and gauge
  2. Subtract current coil and coating inventory
  3. Generate purchase requisitions by supplier and alloy type
  4. Track incoming coil certifications and test reports
  5. Maintain minimum coil safety stock by diameter and gauge

Watch for: Coils are heavy and require specific storage and handling equipment; Coating formulas are proprietary and shelf-life limited

Line setup and changeover coordination

Starts when: Before each scheduled production run

  1. Generate detailed changeover checklist for tooling, mandrels, seaming rolls and coating applicators
  2. Pull required coils and coatings to the line staging area
  3. Create first-article inspection points for diameter, height, seam integrity and coating thickness
  4. Record setup time and any adjustments made

Watch for: Changeover crews must follow exact sequences to avoid damaging expensive tooling; Coating system flush and calibration must be verified before production begins

In-process quality testing and logging

Starts when: Every production shift and on each coil splice

  1. Create shift checklists for seam teardown, coating weight, pressure testing and visual defects
  2. Log test results by coil lot and production time
  3. Flag any out-of-spec conditions for immediate line stop
  4. Compile lot traceability records for each pallet

Watch for: Seam and coating tests are destructive and must be performed at defined frequencies; All test equipment requires daily calibration records

Finished goods inventory and shipment preparation

Starts when: End of each production run and when shipment is due

  1. Record completed pallet counts and locations in the warehouse
  2. Generate customer-specific labels with lot codes and barcodes
  3. Build load sheets by truck or customer order
  4. Draft bill of lading and certificate of conformance documents
  5. Track carrier arrival and loading times

Watch for: Cans are easily dented and must be palletized with proper stretch wrap and corner boards; Some customers require specific pallet patterns and load heights

Regulatory and compliance documentation

Starts when: Monthly, quarterly and on customer request

  1. Compile production, test and lot traceability records
  2. Generate coating usage and waste reports
  3. Track and warn before permit, license or test equipment calibration due dates
  4. Assemble customer-required compliance packets

Watch for: Food can customers require specific documentation packages the owner confirms meet their requirements; Scrap metal and waste coating must be tracked for environmental reporting
