CNC Aluminum PVC Profile Bending Machine

This CNC Aluminum PVC Profile Bending Machine processes aluminum, PVC, UPVC, thermal break, stainless steel, and copper profiles into curved shapes for window and door frames, curtain wall elements, architectural trims, and industrial components. Hydraulic thrust options of 20, 25, or 40 tons are available, and the CNC controller with a 10-inch touchscreen supports digital programming of multi-radius arcs, full circles, ellipses, and compound curves. Positioning accuracy is specified at ±0.02 mm across the servo-controlled X, Y, and Z axes.

• 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

The CNC Aluminum PVC Profile Bending Machine operates with the operator loading the profile onto the worktable and securing the forming belt and roller molds matched to the profile cross-section. The desired bend geometry — whether a C-shape, U-shape, full circle, or multi-radius curve — is programmed on the 10-inch touchscreen or imported via USB. The servo-controlled X, Y, and Z axes position the profile and bending rollers, while the hydraulic station applies the selected thrust. The roller molds, made from hardened steel with an optional PU coating to prevent surface marking, guide the profile through the programmed curve. After the bend cycle, the finished profile is removed. Custom forming belts and molds are available for specific profile shapes to achieve the required bend radius without deforming the cross-section.

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.
