Deep-learning inspection of superabsorbent polymer production
LG Chem reported detecting 99.75% of defective foreign material on a polymer production line
Problem
Foreign material forced production stoppages and full inspections on LG Chem's superabsorbent polymer line.
Approach
LG Chem installed cameras at its Gimcheon plant in 2018. It applied a deep-learning algorithm to production images to detect foreign material.
Results
Takeaway
The reported figure concerned foreign-material detection on a specific production line, rather than the overall factory defect rate.
