Features
Optimized for tight-radius bends in Ø4–15.88mm tubes (pneumatic/hydraulic models), this servo-driven system delivers ±0.1mm pitch accuracy and ≤10% ovality at 7,000–8,000 pcs/shift throughput. Processes U-shaped profiles with <38.1mm center distances, 180° bends in 1.5s, and cuts <600mm lengths in 5s – engineered for refrigeration coils, micro-heat exchangers, and compact hydraulic fittings.
Micro-Tolerance Bending Dynamics
Three-axis servo linkage maintains ±0.05° bend angle accuracy even at R7–R30 radii (±0.1mm positional tolerance). Logic-controlled mandrel system compensates for springback on thin-walled tubes (≥0.3mm thickness).
High-Density Small U-Profile Optimization
Dedicated for mini U-spans (12.7–38.1mm center distance): Auto-calibration jaws handle Ø4–13mm tubes pneumatically, while hydraulic mode supports Ø15.88mm heavy-wall tubing without deflection.
Rapid-Change Tooling Ecosystem
Swap bending dies/cutters in 5,000 units (Ovality SD ≤0.8%).
Energy-Smart Production Scaling
2kW motor + 1.1kW cutting drive operates at 0.4–0.6MPa air pressure (7.3m³/h max). 1.5×0.72m footprint fits lean lines, producing ≥875 pcs/hour at 350kg machine weight.
Application
Filter Dryer Line
Mesabi Tube Line
