CEF extrusion profile bending deformation
Sorun Belirtisi
The CEF extruded profile continuously bends after cooling, with a bending deviation >5mm/m
Neden Analizi
Uneven cooling of each face of the profile leads to shrinkage differences; uneven flow velocity at the die outlet makes the wall thickness of the profile different; the haul-off and extrusion center lines are not aligned, producing lateral force
Çözüm
1) Optimize the cooling system to ensure uniform cooling of each face; 2) Adjust the die to make the flow velocity of each wall uniform and the wall thickness consistent; 3) Align the haul-off and extrusion center lines; 4) Increase the length of the sizing sleeve for sufficient sizing before cooling
Temel Çıkarım
Profile bending is caused by uneven cooling and uneven flow velocity; homogenization and alignment are the key to solving it
