POE extrusion profile bending deformation
Fenómeno del problema
POE extruded profile shows continuous bending after cooling, bending amount >5mm/m
Análisis de la causa
Uneven cooling of each face of the profile causes shrinkage differences; uneven die output flow velocity makes each wall thickness of the profile different; haul-off and extrusion centerline not aligned, producing lateral force
Solución
1) Optimize cooling system to ensure uniform cooling of each face; 2) Adjust the die so that flow velocity of each wall is uniform and wall thickness consistent; 3) Align haul-off with extrusion centerline; 4) Increase sizing sleeve length, cool after full sizing
Conclusión clave
Profile bending is caused by uneven cooling and uneven flow velocity; uniformization and alignment are the solution key
