Understanding Deformation
in Aluminum Extrusion
Understanding bending, bowing, waviness and
stability control in complex aluminum extrusion production.
Why Deformation Happens?
Wide profiles are more sensitive to bending and flatness variation.
Different cooling rates may create internal stress imbalance.
Internal stress may cause deformation after cooling or machining.
Thin-wall profiles have lower structural rigidity during production.
Improper stretching may increase bowing and profile instability.
Complex hollow structures are more difficult to control during extrusion.
Common Deformation Types
These conditions may result in different deformation behaviors on wide and thin-wall aluminum profiles.
1. Bending
Long profiles may deform during cooling and handling.
2. Bowing
Large hollow profiles may develop arching due to stress imbalance.
3. Waviness
Surface waviness may appear on thin-wall or wide extrusion profiles during cooling and transfer.
How We Reduce Deformation Risks?
Long profiles require controlled stretching and handling to maintain straightness consistency.
Reducing stress imbalance during profile cooling.
Maintaining stability during profile transfer and storage.
Reducing deformation risks on complex profile geometries.
Monitoring profile straightness and flatness before machining.
Controlled support helps reduce deformation during production.
