Glass Fibre extruded profile bending deformation
Sorun Belirtisi
Glass Fibre extruded profile after cooling shows continuous bending, deflection >5mm/m
Neden Analizi
Profile faces cooled unevenly causing shrinkage differences; die exit flow velocity uneven making profile wall thicknesses different; haul-off and extrusion centerline misaligned producing lateral force
Çözüm
1) Optimize cooling system to ensure uniform cooling of each face; 2) adjust die to make each wall flow velocity uniform and wall thickness consistent; 3) align haul-off and extrusion centerline; 4) increase sizing sleeve length, cool after full sizing
Temel Çıkarım
Profile bending is caused by uneven cooling and uneven flow velocity; uniformization and alignment are the solution key
