Hollow Stainless Tube Hook Bending Machine | Rotary Die
Watch a rotary bending machine form small hooks from hollow stainless steel tube with clean, kink-free bends - compact hardware parts per stroke.
Key Specifications
- Materials
- Small-diameter hollow stainless steel tube
Key Features
- Bends thin-wall hollow stainless tube without kinks or flattening
- Rotary wrap-around die keeps the polished surface mark-free
- Forms hooks and L-bends in one quick stroke
- Simple manual feed - minimal operator training needed
How Are Hollow Stainless Tubes Bent Into Hooks Without Kinks?
Short answer: With a rotary wrap-around die sized for thin-wall tube. This video shows a benchtop bending machine forming small hooks and L-bends from hollow stainless steel tube - the tube wraps around the die instead of being crushed, so the round profile stays clean with no flattening or surface marks.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Show | Open tube ends in hand | Thin-wall hollow stainless confirmed |
| Feed | Manual tube insertion into the die | Correct bend position every time |
| Form | Rotary wrap-around die | Kink-free hook bend in one stroke |
| Check | Part shown in palm | Round profile, clean polished surface |
Key Applications
- Display, retail and pegboard hooks
- Small stainless hardware for racks and frames
- Appliance and furniture tube components
- Workshops bending thin-wall tube by hand today
Rotary Tube Bending vs. Simple Press Bending
| Criterion | Press bending | Rotary wrap-around bending |
|---|---|---|
| Thin-wall profile | Flattens and kinks | Stays round |
| Bend radius | Sharp, stressed | Smooth, consistent |
| Surface finish | Tool marks common | Mark-free polish kept |
| Cycle time | Slow repositioning | One quick stroke |
FAQ
Will the machine crush thin-wall hollow tube? No - the die set is matched to the tube diameter and wall thickness, so the profile wraps around the die and stays round.
What hook shapes can be produced? Single-bend hooks, L-bends and similar small hardware shapes as shown; die geometry is customized to your part.
Is production suitable for small parts in high volume? Yes - manual feed with a fast rotary stroke gives repeatable parts, and the benchtop footprint suits small-part batches.
