PETG extruded pipe surface corrugation
Problembeschreibung
Periodic or continuous corrugated textures appear on the surface of PETG extruded pipes.
Ursachenanalyse
Extrusion speed too high causing melt fracture, die temperature low, haul-off speed not matching extrusion speed.
Lösung
Reduce the extrusion speed or increase the die temperature; match hauling with extrusion speed; polish the die to reduce friction.
Wichtigste Erkenntnis
PETG pipe surface corrugation is the result of poor coordination between extrusion and hauling.
