Umprotech CNC Tube Bender — Ø3.5in x 20ft, 3.0D Mandrel
All-electric mandrel CNC tube bender engineered for US job shops, OEMs, and fabrication cells requiring precise, repeatable bends on long and large-diameter tubes. Designed for complex geometries, high-mix production, and tight-radius work across automotive, aerospace, and industrial applications.
Max Tube OD: Ø3.5" · Max Length: 20 ft · Mandrel CLR: up to 3.0×D · Servo Axes: 3, 5, or 8
Key advantages for US buyers
- Mandrel bending up to 3.0×D CLR — minimize ovality and collapse on tight-radius bends, even with thin-wall or high-strength tubes.
- Handles up to Ø3.5" tube and 20 ft lengths — ideal for headers, frames, hydraulic lines, and architectural work.
- All-electric servo-driven axes (3, 5, or 8-axis) deliver high repeatability for production runs and complex multi-plane parts.
- Multi-radius tooling supports families of parts and reduces changeover time for high-mix jobs.
- 3D programming with simulation and anti-collision routines — reduce setup errors and protect tooling on long or intricate tubes.
- Automation options: booster for ultra-tight radii, auto loader/unloader for long tubes, and weld seam detection for oriented bends.

Capabilities & typical applications
This CNC tube bender is a core asset for shops producing precision-bent tubes for demanding sectors. It integrates seamlessly into standalone bending cells or as part of a laser-cutting, saw, and welding workflow.
- Automotive and motorsports headers, roll cages, and chassis components
- Hydraulic, HVAC, and process piping lines
- Aerospace and defense tubing, fuel and brake lines
- Furniture and architectural tube structures
- High-mix/low-volume production, prototypes, and repeat contract runs
Implementation & support for US shops
We partner with US job shops, OEMs, and integrators to ensure a smooth transition from quote to production. Our team reviews your part drawings, materials, and thickness ranges to confirm fit and cycle times before purchase.
We assist with pre-installation planning (power, floor space, workflow), basic programming, bend sequencing, and tooling strategies. Onsite or remote training is available to get your team bending parts quickly and confidently.
- Application review and cycle time confirmation
- Integration with existing saw, laser, or welding workflows
- Training and handover for operators and programmers
Next step: Send us your sample parts (DXF/STEP/PDF) and we’ll confirm fit, cycle time, and the best configuration for your shop.
