Análisis de la causa
The addition amount of color masterbatch fluctuates or is unevenly dispersed, the regrind ratio is inconsistent, and processing temperature fluctuations affect the pigment stability.

Use a metering pump to accurately add the color masterbatch; stabilize the processing temperature and the regrind ratio; use heat-resistant pigments.
Conclusión clave
PCTG color difference requires process stability and a precise color matching system.
