Glass Fibre surface tiger-skin pattern
Sorun Belirtisi
Glass Fibre injection molded product surface tiger-skin pattern, alternating light and dark stripes, width 2-5mm
Neden Analizi
Injection speed unstable, melt front fluctuates, sometimes fast sometimes slow; mold temperature too low <30°C, front rapidly cools
Çözüm
1) Multi-stage injection slow-fast-slow to stabilize front; 2) raise mold temperature to 40-50°C; 3) increase injection pressure for stable advance
Temel Çıkarım
Tiger-skin pattern is caused by injection front instability; multi-stage injection and high mold temperature are key
