Copper Tube, Small Radius, 3D Coil, Thin Wall, Wrinkle-Free
Industry Tube Characteristics
Primarily Purple Copper Tubes (TP2), Aluminum, And Some Stainless Steel.
Form
Common U-Bends, L-Bends, And Complex Continuous Coil Tubes (Serpentine Coils).Bending Technology & Challenges (Extended Knowledge)
Challenge
Copper Is Soft And Thin-Walled, Prone To Flattening Or Wrinkling At The Bend Point
Solution
Recommend All-Electric CNC Tube Benders Or Specialized Coil Bending Machines.
Core Technical Points
Mandrel Selection: For Extremely Small Radius Bends (1D Or 1.5D), A Spherical Mandrel Must Be Used To Support The Tube Wall，And Prevent Collapse.
Chip-Free Cutting: The HVAC Industry Demands Extremely High Internal Cleanliness. Post-Bending Cutting Must Be Chip-Free To Prevent Compressor Blockage.
