Servo-driven accuracy for critical tube shapes

The Umprotech all-electric mandrel CNC tube bender is designed for the US market and engineered for precision on bends up to Ø3.5″ and 20 ft tube length. Fully servo-driven axes deliver repeatable, stackable bends with tight tolerance control, ideal for production runs and complex geometries.

Mandrel support up to 3.0×D CLR

A robust mandrel system with mandrel extractor, wiper die, and pressure die assist supports centerline radii up to 3.0×D, reducing ovality and collapse on tight-radius bends. The integrated anti-wrinkle system keeps thin-wall and high-strength tubes in shape, even at aggressive radii.

Multi-radius tooling and flexible setups

Multi-radius tooling allows multiple CLR setups on a single machine, cutting changeover time and keeping families of parts on one bender. Auto-lubrication extends tooling life and reduces manual maintenance, supporting long production runs with consistent surface quality.

3D programming, simulation, and anti-collision

The control supports 3D programming with simulation so operators can visualize bend sequences before running production. XYZ/rotation import streamlines programming from CAD or measuring arms, while anti-collision routines help protect tooling, mandrel, and machine structure when working with long, complex tubes.

Automation and high-throughput options

Boost capabilities further with a booster for ultra-tight radii, plus auto loader/unloader options for hands-off loading of long tubes. A weld seam detection option keeps seam location under control for oriented bends and downstream assembly requirements.

*Actual performance varies with material grade, wall thickness, tooling design, and process setup.
