Quality Control Checklist: ISO 9001 Ready
A practical shop-floor QC checklist for metal manufacturers — incoming inspection, in-process controls, finished goods, and non-conformance management.
Incoming Material Inspection
Verify supplier MTC matches PO grade and heat number
Check dimensions: thickness/diameter/length against PO tolerance
Perform hardness or tensile test per applicable standard (IS/ASTM/EN)
Check surface condition: no cracks, laminations, excessive scale
Record lot number, heat number, quantity in incoming inspection register
Quarantine non-conforming material and raise NCR immediately
Never let NCR material enter production without formal DMR
In-Process Quality Controls
First piece inspection: check first 5 pieces before running full batch
Dimensional checks: frequency per control plan (every 25-50 pieces typically)
Tool wear monitoring: replace before they cause dimensional drift
Heat treatment: temperature chart recorder signed by authorized person
Weld inspection: visual + dimensional on every weld. NDT per specification.
Final Inspection Pre-Dispatch
100% visual inspection for surface defects, burrs, identification markings
Random dimensional sampling per AQL level (AQL 1.0 for critical dimensions)
Hardness/tensile test per standard on sample from each heat/batch
Packing inspection: correct packing per export or domestic standard
Tag/label check: heat number, lot number, grade, quantity, customer PO
Non-Conformance Management
Raise NCR for every deviation — incoming, in-process, customer complaint
Segregate and tag: RED = reject, YELLOW = pending review
Root cause analysis within 48 hours: 5-Why or Fishbone diagram
Corrective action: short-term (contain) + long-term (prevent recurrence)
Close NCR only after verifying corrective action effectiveness
