Aluminum Ring Handle Bending Machine | Rectangular Pulls
A benchtop rotary bender forms rectangular ring pull handles from hollow flat aluminum strip - four corners, mark-free finish, identical handles per batch.
Key Specifications
- Materials
- Hollow flat aluminum strip profile
Key Features
- Forms four-corner rectangular ring handles from flat strip
- Hollow profile stays open - no collapse at the bends
- Wrap-around pins produce clean square corners
- Manual indexing between bends keeps the cycle fast
How Are Rectangular Aluminum Ring Handles Bent Without Collapsing?
Short answer: On a rotary pin bender that supports the hollow profile through every corner. This video shows rectangular ring pull handles being formed from hollow flat aluminum strip: the operator feeds the bar, sweeps it around the bend pin, indexes to the next corner, and four bends later a crisp ring handle joins the identical row on the table.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Stock | Hollow flat aluminum strip | Light, rigid handle profile |
| First bend | Clamp block and rotary pin | Square corner, section stays open |
| Index | Strip repositioned at the pin | Second, third and fourth corners |
| Batch | Finished row on the table | Identical ring handles |
Key Applications
- Rectangular ring pulls for cabinets and doors
- Hollow-profile aluminum handle production
- Appliance and enclosure grip frames
- Hardware shops replacing hand bending with a benchtop station
Rotary Pin Bending vs. Press Bending for Hollow Strip
| Criterion | Press bending | Rotary pin bending |
|---|---|---|
| Hollow section | Collapses or wrinkles | Stays open and true |
| Corners | Rounded, inconsistent | Crisp and square |
| Multi-bend parts | Re-clamp each corner | Simple indexing |
| Surface finish | Marks common | Clean, coating-ready |
FAQ
What profile is used for these ring handles? Hollow flat aluminum strip, shown in the video before and after bending; width and wall thickness are matched to the handle size you need.
How many bends make one ring handle? Four - the operator indexes the strip at the same pin for each corner, so all four radii stay identical.
Can the handles be powder coated after bending? Yes - the wrap-around action leaves the surface clean and unmarked, so parts go straight to finishing.
