High-Precision CNC Aluminum & PVC Profile Bending Machine

This CNC Aluminum & PVC Profile Bending Machine is purpose-built for architectural profile fabrication, including curtain walls, facades, arch windows, and PVC window frames. Equipped with a 3-roller synchronized bending system and servo-driven control, it delivers smooth, distortion-free curves with ±0.5mm accuracy. Compatible with both aluminum extrusions and PVC/UPVC profiles, the machine supports multi-radius bending in a single setup, significantly improving production efficiency while reducing material waste. CE certified and fully customizable, it is the ideal solution for modern architectural bending applications.

• Multi-material compatibility: The CNC Aluminum PVC Profile Bending Machine bends aluminum, PVC, UPVC, thermal break, stainless steel, and copper profiles. Tooling sets can be changed to accommodate different material grades and cross-sections within the machine's capacity.
• 3-axis CNC positioning: Servo motors on X, Y, and Z axes are driven through a CNC controller with a 10-inch touchscreen. Positioning accuracy is ±0.02 mm. Operators program multi-radius shapes, arcs, and compound curves directly on the interface or import data via USB.
• Hydraulic thrust options: Three hydraulic station configurations are offered — 20-ton, 25-ton, and 40-ton — selected based on the profile material, wall thickness, and bend radius required. The hydraulic pump operates with reduced noise compared to standard industrial units.
• Bending shape range: The machine produces C-shape, U-shape, S-shape, full circle, ellipse, multi-radius combinations, and custom arcs. Forming belts and roller molds can be customized to match the profile cross-section for optimal bend quality.

How It Works

Profile Loading

Aluminum or PVC profiles are placed into the feeding guide and securely clamped to prevent slipping or twisting during the bending process.

2. 3-Roller Synchronized Bending

The machine uses three precision rollers:

Top roller – drives the profile forward

Two side rollers – move along CNC-controlled trajectories to apply uniform pressure

This synchronized movement ensures consistent arc formation without surface damage or deformation.

3. Servo-Driven Precision

Servo motors control roller positioning in real time, providing accurate feedback and repeatable bending performance. The CNC system compensates for material spring-back automatically.

4. Multi-Radius Programming

Operators can program multiple bending radii, arc segments, and full circles directly from CAD drawings. The machine executes complex curves without manual intervention.

5. Continuous Production

Once the program is set, the machine repeats the bending cycle with high consistency, making it suitable for both mass production and custom architectural projects.

Process Flow:

Profile Loading → CNC Program Input → 3-Roller Synchronization → Servo Positioning → Multi-Radius Bending → Finished Curved Profile

Key Components

CNC Controller: 10-inch touchscreen with user interface for programming bend angles, radii, and multi-radius sequences. USB port supports program import and export. The controller manages axis motion, hydraulic pressure, and cycle timing.

Hydraulic Station: Available in 20-ton, 25-ton, and 40-ton configurations. Uses an imported oil pump selected for stable pressure output and quiet operation. The hydraulic circuit includes a pressure relief valve and a filter.

Roller Molds: Fabricated from hardened steel with an optional PU coating. The coating helps prevent scratching or marking on coated, anodized, or painted profile surfaces. Mold sets are interchangeable for different profile cross-sections.

Transmission: Taiwan HIWIN linear guide rails carry the moving axes. Precision gearboxes and servo motors provide the positioning accuracy for the X, Y, and Z movements.
