Color change at product weld lines
Sorun Belirtisi
The color of the weld line area is inconsistent with the surroundings, with obvious color difference
Neden Analizi
Colorants enrich or are diluted at the weld interface; molecular orientation at the weld differs from the surroundings, causing refraction differences; local overheating causes slight degradation
Çözüm
Reduce colorant addition amount; optimize gate position to avoid weld lines on visible surfaces; optimize the temperature field to reduce overheating
Temel Çıkarım
Weld line color change is especially obvious in high-gloss products
