Advanced CNC Tube Bending Capabilities
Our precision bending equipment combines mandrel support, CNC servo control, and material engineering to deliver consistent curves that meet tight tolerances and functional requirements.
Mandrel-Supported Bending
Internal mandrel support prevents collapsing and maintains wall thickness uniformity. Achieves smooth, repeatable curves with minimal springback.
Precision Tolerance Control
Tight bend radius tolerances (±0.3–0.8 mm) controlled through CNC programming and material characterization. Springback calculations ensure dimensional accuracy.
Multi-Plane & Complex Bends
Sequential bending enables multi-directional curves and compound bends in a single tube without intermediate annealing.
