PU screw slipping
Sorun Belirtisi
During PU extrusion, the screw slips, feed does not advance, output drops sharply
Neden Analizi
PU pellets melt too early in the feed section, forming a lubricating film causing screw slip; feed section temperature too high
Çözüm
1) Lower feed section temperature by 10-15°C to delay melting; 2) Deepen feed section flight to increase material gripping force; 3) Dry pellet surface to reduce lubrication
Temel Çıkarım
Screw slipping is caused by premature melting; cooling the feed section is key
