Fiber enrichment at the weld line area
Sorun Belirtisi
White fiber aggregation is visible to the naked eye at the weld line of the product, and the strength of this area is far lower than other parts
Neden Analizi
The two melt fronts carry glass fibers to aggregate at the weld interface when converging; poor venting in the convergence zone prevents the fibers from redistributing uniformly
Çözüm
Optimize gate position and number to reduce weld lines; increase mold temperature to extend fiber redistribution time; design overflow wells at weld lines to discharge enriched fibers
Temel Çıkarım
Glass fiber aggregation at the weld line is the structural cause of the sharp drop in mechanical strength in this area
