EVOH Surface Tiger Stripes
Sorun Belirtisi
EVOH injection molded product surfaces show tiger stripes, alternating light-dark bands 2-5mm wide
Neden Analizi
Injection speed unstable, melt front fluctuating fast and slow; mold temperature too low <30°C, front rapidly cooling
Çözüm
1) Multi-stage injection slow-fast-slow to stabilize the front; 2) Increase mold temperature to 40-50°C; 3) Increase injection pressure for stable advancement
Temel Çıkarım
Tiger stripes are caused by unstable injection front; multi-stage injection and high mold temperature are key
