AE-Based Signal Verification for Micro-Defect Detection in Drawing Process
[ Field Issue ]
Problem
Needs
Micro contaminants intrude during drawing → defects
Real-time detection of contamination/anomalies
Reactive QC only → no immediate response
Real-time monitoring for instant response
High-speed continuous drawing process is prone to defects from micro contaminant intrusion. Reactive QC alone can’t respond in time — real-time monitoring is needed
[ Verification & Application ]
Tested on live equipment with contaminants from 0.1mm to 2mm. Most cases showed detectable micro-defect signals
