Poor EEA extrusion film thickness uniformity
ظاهرة المشكلة
EEA extruded film transverse thickness deviation ±15% exceeding the ±5% industry standard
تحليل الأسباب
Unreasonable die runner design causing uneven melt flow in the wide die; EEA melt elasticity large, uneven extrusion swell; uneven air ring cooling
الحل
1) Adopt coat-hanger die design to ensure uniform transverse flow; 2) Fine-adjust die gap ±0.02mm; 3) Optimize air ring air volume and angle for uniform cooling; 4) Add a small amount of low-elasticity resin to reduce swell difference
الخلاصة الأساسية
Film thickness uniformity requires coordinated optimization from three aspects: die design, gap adjustment and cooling
