Color streaks/uneven color mixing on products
Fenómeno del problema
Stripes or patterns of varying color depth appear on the product surface
Análisis de la causa
Color masterbatch is not fully dispersed in the blend; the mixing capacity of the screw mixing section is insufficient; the color masterbatch carrier resin is incompatible with the alloy matrix
Solución
Select special color masterbatch with good dispersibility; add screw mixing elements (kneading blocks, toothed elements); select a color masterbatch carrier compatible with the alloy matrix
Conclusión clave
Uneven color mixing is rooted in the insufficient mixing capacity of the dispersion system
