Uneven dispersion of color masterbatch; pigment orientation during injection causing uneven color distribution; barrel temperature fluctuation causing color change
Çözüm
1) Use the color masterbatch masterbatch method to ensure uniform dispersion; 2) Reduce injection speed to reduce pigment orientation; 3) Stabilize barrel temperature to ±2°C
Temel Çıkarım
Color difference is caused by uneven dispersion and orientation; masterbatch method and stable processing are key
