Glass Fibre screw slipping
Problembeschreibung
During Glass Fibre extrusion, screw slips, feed does not advance, output drops sharply
Ursachenanalyse
Glass Fibre pellets melt too early in feed section forming lubricating film causing screw slip; feed section temperature too high
Lösung
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
Wichtigste Erkenntnis
Screw slipping is caused by premature melting; cooling feed section is key
