Color streaks/uneven color mixing on products
Problem Phenomenon
Stripes or patterns of varying color depth appear on the product surface
Cause Analysis
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
Solution
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
Key Takeaway
Uneven color mixing is rooted in the insufficient mixing capacity of the dispersion system
