Bending Deformation of CMC Extruded Profile
Fenómeno del problema
CMC extruded profile shows continuous bending after cooling, with deviation >5mm/m
Análisis de la causa
Uneven cooling of each face of the profile causes differential shrinkage; uneven die outflow velocity makes the wall thicknesses of the profile different; misalignment of haul-off and extrusion centerlines produces lateral force
Solución
1)Optimize cooling system to ensure uniform cooling of each face; 2)Adjust die to make flow velocity of each wall uniform and wall thickness consistent; 3)Align haul-off and extrusion centerlines; 4)Increase sizing sleeve length for full sizing before cooling
Conclusión clave
Profile bending is caused by uneven cooling and uneven flow velocity; homogenization and alignment are the key to solution
