Umprotech CNC Tube Bender — Ø4.0in x 20ft, 4.0D Mandrel
All-electric, mandrel-equipped CNC tube bender engineered for US job shops, OEMs, and fabrication cells. Handles up to Ø4.0″ tube, 20 ft lengths, and 4.0×D centerline radius with full servo-driven precision. Designed for consistent results on mid- and large-diameter tube work where repeatability, part quality, and setup flexibility matter.
Max Tube OD: Ø4.0″ · Max Length: 20 ft · Max CLR: 4.0×D · Axes: 3, 5, or 8 (servo-driven)
Key advantages for US buyers
- Handles tube diameters up to Ø4.0″ and lengths up to 20 ft for hydraulic, structural, and process applications.
- Mandrel bending up to 4.0×D CLR with extractor, wiper die, and pressure die assist for tight-radius, thin-wall, and high-strength tube jobs.
- All-electric, servo-driven axes (3, 5, or 8) deliver repeatable, stackable bends and precise control for high-mix or production runs.
- Multi-radius tooling supports complex assemblies with varied bend radii in a single setup.
- 3D programming, simulation, and anti-collision monitoring minimize setup time and protect tooling on multi-plane parts.
- Automation-ready: booster for tight radii, auto loader/unloader, and weld seam detection options for throughput and quality.

Capabilities & typical applications
This CNC tube bender is a core asset for US fabrication shops handling mid- and large-diameter tube work—whether as a standalone cell or as part of a laser, saw, and welding workflow. Its capacity and mandrel setup make it a fit for both high-mix prototyping and repeat production.
- Hydraulic and process lines, industrial piping, and HVAC runs up to 20 ft
- Automotive and truck exhaust, chassis, and frame components
- Architectural tube work, railings, and custom structures
- General fabrication: brackets, supports, and assemblies requiring multiple bend radii
- High-mix/low-volume and production batches with tight tolerance and surface finish requirements
Implementation & support for US shops
We partner with US job shops and OEMs to ensure a smooth transition—reviewing your parts, material grades, and floor plan to confirm fit. Our team assists with pre-install planning (power, material flow, safety), initial programming, tooling strategies, and operator training so your team is productive from day one.
- Pre-install review: power, floor space, and access
- Part and material analysis to confirm machine fit
- Support for basic programs, bend sequencing, and tooling setup
- Operator training and commissioning for fast ramp-up
Next step: Send us a sample part or drawing (DXF/STEP/PDF), and we’ll confirm fit, cycle time, and the right configuration for your shop.
