Extrusion Cross-Section Dimensional Sampling Inspection

Periodic inspection template for sampling aluminum extrusion cross-sections against the print to verify wall thickness, overall dimensions, and process stability.

Inspection Identification and Sampling Plan

• Job, press, alloy, and profile revision identified
• Sampling point recorded
• Reference print or approved drawing available at inspection station
• Measurement method and tool identified
• Measuring tool calibration status verified

Profile Setup and Sample Condition

• Sample is cut cleanly and cross-section is readable
• Sample orientation matches the print reference orientation
• Burrs, distortion, or cut damage do not interfere with measurement
• Sample identification matches the lot or run being inspected
• Photo of sample cross-section attached

Critical Dimensional Measurements

• Wall thickness at primary critical location
• Wall thickness at secondary critical location
• Overall profile width
• Overall profile height
• Critical feature location or slot width
• Measured dimensions recorded against nominal and tolerance

Process Drift and Trend Review

• Current measurements are within print tolerance
• No upward or downward trend observed versus prior sample
• Die, press, or quench adjustment required
• Out-of-tolerance condition escalated to supervisor or quality

Disposition and Corrective Action

• Disposition selected
• Containment action documented for affected material
• Corrective action owner and due date recorded
