PA66 coloring masterbatch selection
문제 현상
Color streaks appear after adding color powder to natural-color material, batch-to-batch color difference exceeds standard, especially obvious on light-color parts
원인 분석
Color powder disperses unevenly in PA66 low-viscosity melt forming color streaks; batch fluctuations of drying and melt temperature change the matrix hue, and light-color parts are more sensitive to color difference; during on-site troubleshooting, verify item by item according to this mechanism, avoiding blindly adjusting the machine based only on experience
해결 방법
①Switch to carrier-matched color masterbatch to improve dispersion; ②Lock drying and melt temperature parameters; ③First-article color comparison to establish color difference acceptance standards; after adjustment, take continuous samples to verify the effect, confirm stability before resuming mass production
핵심 요약
PA66 coloring prioritizes the color masterbatch route; parameter locking and first-article color comparison system keep color difference stable within the acceptance band; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
