Profile Bending Machine
Achieve Perfect Profile Rolling for Aluminum Extrusions and Steel Structural Sections with Our Advanced Solution.
What is
Profile Bending Machine?
The Profile Bending Machine usually refers to cold bending equipment designed for roll-bending metal sections, including aluminum, steel, and other materials.
30+ years. BIT provides a CNC Profile Bending Machine for big mass-producing profile curved parts. The main use of the Profile Bending Machine is to bend profiles into curves, such as C, U, and S shapes, parabolas, and spirals. We adopt high accuracy servo hydraulics and motors for profile bending machines.
BIT PBC Profile Bending Machines is named as Angle Roll, C Channel Bending Machine, Flat Bar Bending Machine, I Beam Bending Machine, Pipe Rolling Machine, Section Bending Machine, and Tube Rolling Machine.
Note: PBC machines can operate vertically for diameters <1500 mm or horizontally for larger ones to avoid weight distortion.

Bending Accuracy
The PB Series Profile Bending Machine provides perfect profile bending and the highest bending accuracy and is used in various industries and fields that require the highest production quality.
Borisbang Industrial Technology (BIT) Profile Bending Machines can meet the following accuracy requirements:
- Bending roller repeat positioning accuracy of PBA: 0.01 mm;
- Bending roller repeat positioning accuracy of PBC: 0.02 mm;
Consistency and accuracy in every bend for high-volume production. Profile Bending Machines are also referred to as Angle Iron Roller, Profile Rolling Machine, and Section Bender.

Uses of
Profile Bending Machine
Depending on the customer’s request, we can offer a Profile Bending Machine(Section Bending Machine) made of different bending capabilities and various special bending designed tools, depending on the application.
The PBA Series Profile Bending Machine is ideal for bending aluminum profiles widely used in construction, lighting, and architecture. It handles window profiles, curtain wall materials, lighting fixture profiles, and doors and partition doors, providing high precision for complex bending tasks.
The PBC Series Profile Bending Machine excels at bending heavy-duty metal profiles such as angle iron, flat bars, pipes and tubes (including helical parts), and structural beams (T-beams, I-beams/IPE, H-beams/HEA, HEB, ISMB, U-channel). It is ideal for industries like construction, shipbuilding, and manufacturing.

How its
Consist?
BIT’s CNC profile bending machines consist of high-precision components such as motion controllers, servo hydraulics, or servo motors, enabling both standard and complex curve bending.
The profile bending machine typically consists of a frame, shafts, bending rolls, motors, and a control system. The control system governs the shaft and motor, while other components work together seamlessly.
- CNC System: Precision 3D curve bending with no programming needed.
- High Torque & Guide Rail: Minimal flat ends, strong pre-bending with less power.
- Bending Diameter: As small as 1.1 times the top roller diameter.
- Drive: High-torque hydraulic or servo for fewer bending steps.
- Bending Axis: Planetary motion for tight bends and minimal flat ends.
- 3D Support Rolls: Control X, Y, and Z for easy angle and spiral bending.
- Bending Tools: 30 years of expertise, free design.
- Perfect Bending: No cracks, wrinkles, or deformation.

How it Works?
Because the Profile Bending Machine enables high-precision, high-efficiency bending of complex shapes with easy operation, low costs, and reduced assembly operations, it makes cold bending profiles the most cost-effective method.
Pyramid rolling is the standard operation for the PB series profile bending machine without pre-bending. It bends aluminum or steel profiles by passing them through three adjustable rollers arranged in a pyramid shape. The rollers apply force (PBA uses the upper roller, PBC the lower roller), with the distance between them adjusted before each pass to achieve progressively smaller radii until the desired curvature is reached.
- Operators place the metal profile between the rotating rollers.
- As bending begins, the rollers move along the Y-axis, clamp the profile, and apply pressure.
- This process gradually deforms the profile between the rollers, bending it to the desired curvature.
- Finally, the machine achieves the intended bending shape with precision.
When the material properties permit, the PB series profile bending machine’s high torque enables single-pass bending, eliminating multiple forming steps and significantly improving efficiency.
Customer

















Partnerships That Grow
