Aluminum Profile Bending Services
We offer bending services for your aluminum extrusion parts to achieve the shape you require.
Roll Bending
Through continuous bending with multiple rollers, a large radius arc is formed. Suitable for curved or circular aluminum profiles, such as door and window frames, circular structures, and architectural decorations.
Bottoming / Coining
The material is completely pressed into the V-shaped die to form the product, which is completely deformed, with high precision and small springback. It is suitable for aluminum parts with high requirements for angle accuracy.
Air Bending
The material is not completely pressed into the bottom of the die, and the bending is achieved by punching the upper die. High flexibility, low die loss, variable angle bending. Suitable for most aluminum plates and aluminum profiles

What Is Aluminum Bending?
Aluminum bending refers to the controlled deformation of aluminum profiles or extrusions to achieve a desired radius, angle, or curved shape. This process is widely used in architectural frames, automotive components, structural elements, and furniture.
Common Aluminum Bending Methods
Typical methods include roll bending, rotary draw bending, stretch bending, and compression bending. The choice depends on the profile’s geometry, bend radius, and surface finish requirements. Roll bending is ideal for large-radius curves, while rotary draw bending offers precise, tight-radius control.
What Aluminum Alloys Are Suitable for Bending?
Soft alloys such as 6063-T5 and 5052 are more bendable due to their ductility. Harder tempers like 6061-T6 are more prone to cracking and typically require annealing before bending. Alloy and temper selection directly affects bendability and final strength.
Minimum Bend Radius for Aluminum Profiles
The minimum bend radius depends on alloy, temper, wall thickness, and bending method. As a rule of thumb, softer tempers allow tighter bends, while harder materials require larger radii to prevent cracking or surface deformation. Manufacturer bending charts provide specific guidelines.
Factors That Affect Aluminum Bending Quality
Key factors include alloy selection, cross-sectional design, wall thickness, bending direction (with or against grain), tooling precision, and bend speed. Improper setup can cause issues like wrinkling, springback, or surface tearing.
Aluminum Bending vs. Welding or Assembly
Bending provides seamless curves and avoids joints or weld seams, enhancing structural integrity and aesthetics. In contrast, welding or bolted assemblies may introduce weak points or require additional finishing, making bending more desirable for certain continuous profiles.
Surface Finish Considerations During Bending
Surface finishes like anodizing or powder coating should be applied after bending to avoid cracking or discoloration at the bend point. If pre-finished profiles must be bent, protective coatings and slower bending speeds can help minimize surface damage.
Springback in Aluminum Bending
Springback is the tendency of aluminum to partially return to its original shape after bending due to elastic recovery. This effect is more pronounced in harder tempers and requires compensation in tooling or over-bending to achieve the target angle accurately.
Applications of Bent Aluminum Extrusions
Bent aluminum parts are used in curtain walls, window frames, transport infrastructure, boat railings, display structures, and furniture. The bending process allows for continuous, aesthetically pleasing curves without compromising structural performance.
Can Complex Aluminum Profiles Be Bent?
Yes, but complex hollow or multi-chambered profiles require precise tooling and support to prevent distortion or collapse. Specialized bending machines and mandrels are often used to maintain profile integrity during tight-radius or multi-plane bends.
