EMA vacuum vent overflow
ظاهرة المشكلة
EMA extrusion vacuum section overflows, clogging the vent hole
تحليل الأسباب
EMA melt viscosity low, overflowing at the vacuum section; vacuum section temperature too high making viscosity even lower and worsening overflow; improper vent hole design
الحل
1) Lower vacuum section temperature by 5-10°C to increase viscosity; 2) Add baffle above the vent hole to prevent overflow; 3) Increase screw speed to accelerate conveying and reduce residence time
الخلاصة الأساسية
Overflow is caused by low melt viscosity; temperature reduction and baffle addition are key
