EEA Screw Slipping
ظاهرة المشكلة
During EEA extrusion, the screw slips, feed does not advance, output drops sharply
تحليل الأسباب
EEA pellets melt too early in the feeding section, forming a lubricating film causing screw slip; feeding section temperature too high
الحل
1) Lower the feeding section temperature by 10-15°C to delay melting; 2) Deepen the feeding section flight to increase material grip; 3) Dry the pellet surface to reduce lubrication
الخلاصة الأساسية
Screw slipping is caused by premature melting; cooling the feeding section is key
