Industry Tube Characteristics

  • Material: Carbon steel, stainless steel (409, 304), aluminum alloy (6061).
  • Specifications: Wide range of diameters (Ø6mm ~ Ø100mm+), medium to thick wall.
  • Form: Multi-bend (5-20+ bends per part common), compound bends, specific 3D shapes.
Icon

Challenge

  • High productivity requirements; strict tolerances for welding and assembly; crash safety standards.
Icon

Solution

  • CNC multi-stack tube bender + robot loading/unloading.

Core Technical Points

  • Multi-stack tooling: Multiple bend dies on the same machine for different radii without changeover.
  • Push bending / Boost function: Reduces wall thinning on tighter bends.
  • Integration with end forming: Flaring, swaging, beading for connector preparation.
