POE surface tiger skin pattern
Problem Phenomenon
POE injection molded product surface tiger skin pattern, alternating light and dark stripes, width 2-5mm
Cause Analysis
Injection speed unstable, melt front fluctuates, alternately fast and slow; mold temperature too low <30°C, front rapidly cools
Solution
1) Multi-stage injection slow-fast-slow to stabilize the front; 2) Raise mold temperature to 40-50°C; 3) Increase injection pressure for stable advance
Key Takeaway
Tiger skin pattern is caused by unstable injection front; multi-stage injection and high mold temperature are key
