PETG extruded pipe surface corrugation
Fenómeno do problema
Periodic or continuous corrugated textures appear on the surface of PETG extruded pipes.
Análise das causas
Extrusion speed too high causing melt fracture, die temperature low, haul-off speed not matching extrusion speed.
Solução
Reduce the extrusion speed or increase the die temperature; match hauling with extrusion speed; polish the die to reduce friction.
Conclusão principal
PETG pipe surface corrugation is the result of poor coordination between extrusion and hauling.
