Core Performance

Bending Capacity
For Production

The ECO-NC series covers common industrial pipe and square tube bending needs with stable fixed-radius control, fast 90-degree cycles, and repeatable NC positioning.

38
mm

Tube Diameter Range

NC38 through NC89 models cover round pipe diameters from 38 mm to 89 mm depending on wall thickness and material.

0
deg

Maximum Bending Angle

Each ECO-NC model supports bending angles up to 190 degrees for reliable fixed-radius pipe processing.

Bends Per Pipe

Operators can set up to 16 bending steps per pipe for small and medium-sized production runs.

10
deg/sec

Working Speed Range

Model-dependent working speeds from 30 to 65 degrees per second balance productivity and controlled bending quality.

Bending System

Evolutionary Design

Decades of tube bending experience and customer feedback are built into a compact, semi-automatic fixed-radius platform for clear operation and dependable results.

NC tube bender evolutionary design

The ECO-NC hydraulic tube bender is designed around practical human-machine communication, visual status guidance, and warning messages. Its compact layout, semi-automatic bending workflow, and fixed-radius structure help operators produce stable pipe bends with less setup complexity.
