EAA surface tiger stripe pattern
Sorun Belirtisi
EAA injection molded product surface shows tiger stripe pattern with alternating light and dark stripes 2-5mm wide
Neden Analizi
Unstable injection speed, melt front fluctuating fast and slow; mold temperature too low <30°C, front cooling rapidly
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 stripe pattern is caused by unstable injection front; multi-stage injection and high mold temperature are key
