Glass Fibre screw slipping
ظاهرة المشكلة
During Glass Fibre extrusion, screw slips, feed does not advance, output drops sharply
تحليل الأسباب
Glass Fibre pellets melt too early in feed section forming lubricating film causing screw slip; feed section temperature too high
الحل
1) Reduce feed section temperature 10-15°C to delay melting; 2) deepen feed section flight to increase material gripping force; 3) dry pellet surface to reduce lubrication
الخلاصة الأساسية
Screw slipping is caused by premature melting; cooling feed section is key
