DSTDP extruded profile bending deformation
Sorun Belirtisi
DSTDP extruded profile continuously bends after cooling, bending deviation >5mm/m
Neden Analizi
Uneven cooling of each profile face causes differential shrinkage; uneven die discharge flow rate makes profile wall thicknesses different; haul-off and extrusion center line not aligned producing lateral force
Çözüm
1) Optimize cooling system to ensure uniform cooling of all faces; 2) adjust the die to make flow rate uniform and wall thickness consistent; 3) align haul-off and extrusion center line; 4) increase sizing sleeve length, cool after fully sized
Temel Çıkarım
Profile bending is caused by uneven cooling and uneven flow rate; uniformization and alignment are the key to solution
