PBT Color Masterbatch Matching
문제 현상
After PBT coloring, color streaks and color difference appear, and the color of spray-free parts drifts between batches
원인 분석
PBT color matching requires selecting polyester carrier color masterbatch; batch fluctuations in processing temperature and drying change the base color hue; spray-free parts have extremely low tolerance for color difference; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
해결 방법
①Select polyester carrier color masterbatch; ②Lock drying and temperature parameters; ③Match color on the first article and establish acceptance standards; after adjustment, take samples continuously to verify the effect, and resume mass production only after confirming stability
핵심 요약
PBT color matching requires carrier matching plus parameter locking; the color matching system for spray-free parts is the quality guarantee; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
