FYLA Inspection
Rainbow
Quality Control in the Coil Coating Industry
In-line Color & Thickness* Quality Control
Autocalibration and multipoint inspection to get lab accuracy.
*Thickness measurement capability planned by end of 2026.
100% of the Production Measured
Rainbow captures multiple zones every few seconds, contact‑free and unaffected by line speed.
Reports and Real-time alarms
Automatic report generation and real-time alarms.
REAL TIME CONTROL FOR REAL SPEED LINES
Reliable Quality Control
Rainbow is the perfect solution for quality control in continuous processes such as coil coating.
Construction
Large volumes and long production runs leave little room for rework.
Rainbow helps manufacturers ensure consistent visual quality from the start, reducing scrap, avoiding costly downstream issues, and protecting brand reputation in architectural and construction materials.
Home Appliances
Surface quality directly impacts perceived value.
Rainbow enables early defect detection, helping manufacturers maintain high aesthetic standards while minimizing waste and avoiding quality issues that would otherwise appear too late in the process.
Automotive and transportation parts
Consistency, traceability, and zero tolerance for defects.
Rainbow supports stable, repeatable quality control in high‑speed coil processes, helping manufacturers meet strict industry requirements without compromising production efficiency.
