Servo-driven accuracy for 1.5″ tube up to 14 ft

The Umprotech all-electric mandrel CNC tube bender for the US market is engineered for small- to mid-diameter tube up to Ø1.5″ and extended 14 ft length. Fully servo-driven axes deliver repeatable, stackable bends with tight tolerance control—ideal for longer manifolds, chassis rails, and fluid lines where routing space is tight but tube length is not.

Mandrel support up to 3.0×D CLR

A complete mandrel package with mandrel extractor, wiper die, and pressure die assist supports centerline radii up to 3.0×D, helping control ovality, collapse, and wall thinning on tight-radius bends in 1.5″ tube. The integrated anti-wrinkle system stabilizes thin-wall and high-strength tubing when running aggressive layouts along the full 14 ft envelope.

Multi-radius tooling and stable flow

Multi-radius tooling lets you configure multiple CLR stations on a single setup—ideal for long parts that combine tight crossovers, offsets, and longer sweeps. Auto-lubrication maintains mandrels, dies, and sliding elements for long tool life, consistent surface finish, and reduced manual maintenance in continuous production.

3D programming, simulation, and anti-collision

The control platform delivers 3D programming with simulation so operators can verify bend sequences before cutting metal. XYZ/rotation import simplifies programming from CAD or measuring systems, while anti-collision monitoring helps protect small-diameter tooling, mandrel, and machine structure when bending complex multi-plane shapes with long stick-outs.

Automation and high-mix options

Expand capability with an optional booster for ultra-tight radii within the 3.0×D envelope, plus auto loader/unloader systems for hands-off handling of 14 ft blanks. A weld seam detection option maintains seam orientation for safety-critical and cosmetic assemblies in small- to mid-diameter tube.

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