Automate Surface Defect Detection with Vision AI
Learn how vision AI detects surface defects other systems miss.
Add a real-time inspection layer to every line with vision AI for extrusion inspection. Built for the processes where a defect born at the die lives on every meter after it, the operator's spot check samples a continuous product once an hour, and the difference between a hiccup and a scrap pile is how many minutes passed before someone noticed. Whether you're running profiles, pipe and tubing, or aluminum shapes, Roboflow inspects every meter at line speed, with per-run records behind every shipment.

Bring intelligence to every meter today. Stop extrusion defects from becoming kilometer-scale scrap, rejected truckloads, or the die problem discovered at the end of the shift.
What is extrusion inspection with Vision AI?
Extrusion inspection with vision AI uses computer vision models to inspect extruded product continuously at line speed: die lines, drag marks, and streaks on profiles, pickup and tearing on aluminum, voids, sink marks, and contamination, print line legibility on pipe and conduit, and cut end quality. Models trained on your actual product flag defect onset the minute it starts, with per-run records tied to line, die, and lot that support ISO 9001 and listing documentation.
Can Vision AI catch a defect the minute it starts?
Extrusion is the onset hard case: the product is continuous, a die-born defect repeats on every meter that follows, and an hourly spot check at the puller means an hour of scrap rides on the check you just missed. Deep-learning models trained on your actual profiles, materials, and lighting watch every meter as it leaves the die, tell a persistent die line from a transient speck, flag onset within moments of the first bad meter, and hold that judgment across products, colors, and gloss levels, which turns the same defect from a kilometer of scrap into a die adjustment.
Does this replace our laser micrometers and profile scanners?
No. Laser micrometers and profile scanners keep owning dimensions: OD, wall, ovality, and the profile's geometry, and ultrasonic gauges keep wall thickness on pipe. Vision AI adds the layer dimension can't see: the die line on a profile that measures perfectly, the gloss shift, the contamination speck, the print line too faint to certify, and the cut end that will scrap the stick at installation. Dimensional data and visual findings land in the same per-run record, and surface texture often names the wearing die before the dimensions drift.
Can it integrate with our line PLCs, pullers, and MES?
Yes. Roboflow Inference exposes a standard API and supports common industrial protocols, so extrusion inspection events flow into your existing systems: line and puller PLCs from Allen-Bradley and Siemens, MES and ERP platforms like SAP and Oracle, and SCADA and HMI platforms like Ignition and AVEVA, through REST, MQTT, OPC UA, and direct database writes. PLC-level integration raises an alarm or marks product the moment onset is detected, and every event carries line, die, run, meter position, imagery, and disposition, with a full audit trail behind every shipment.
