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