Die and Tooling Changeover Verification (Extrusion)

Inspection template for verifying die mounting, alignment, purge, and first-piece quality after an extrusion profile changeover before releasing the line to production.

Inspection Details and Authorization

• Changeover identification matches the active job, die, and tooling set
  Record the product code, die number, tooling set, and line number being verified.
• Inspection performed by authorized setup or quality personnel
• Lockout-tagout applied and verified before die or tooling adjustments
• Area cleared for changeover verification and nonessential personnel excluded

Die Mounting and Mechanical Alignment

• Die is fully seated, secured, and fasteners are torqued to specification
• Die face, adapter, and tooling show no visible damage, galling, or contamination
• Die centerline is aligned to the line centerline within tolerance
• Bolts, clamps, and support hardware are present and properly installed
• Heaters, thermocouples, and temperature controls are connected and functioning

Purge, Cleanout, and Material Transition

• Previous polymer or alloy material has been fully purged from the die and barrel transition zone
• No visible buildup, carbonization, or degraded material remains at the die exit
• Purge material collected and disposed of according to site waste procedure
• Material transition completed without contamination, streaking, or color carryover

Startup Conditions and Safety Controls

• Machine guards, barriers, and access covers are installed before startup
• Emergency stop devices are accessible and functional
• Ventilation, fume extraction, or dust collection is operating as required for the material in use
• PPE required for startup verification is worn

First-Piece Quality Verification

• First-piece profile dimensions are within specification
  Enter the measured deviation from specification for the critical profile dimension, or use the site-defined measurement method.
• First-piece surface quality is acceptable with no burn marks, voids, tears, or die lines beyond limit
• Color, gloss, and appearance match the approved standard sample
• First-piece sample approved by quality or authorized release personnel

Release to Production

• Any deficiencies or non-conformances documented with corrective actions assigned
• Line released for production run
• Inspector signature
