PETG extruded pipe surface corrugation
문제 현상
Periodic or continuous corrugated textures appear on the surface of PETG extruded pipes.
원인 분석
Extrusion speed too high causing melt fracture, die temperature low, haul-off speed not matching extrusion speed.
해결 방법
Reduce the extrusion speed or increase the die temperature; match hauling with extrusion speed; polish the die to reduce friction.
핵심 요약
PETG pipe surface corrugation is the result of poor coordination between extrusion and hauling.
