Brass Flat Bar S-Hook Bending Machine
Watch a hydraulic markless bending machine fold brass flat bar into double S-hooks - clean bends with polished radius and no surface marks, part after part.
Key Specifications
- Materials
- Brass-colored flat bar stock
Key Features
- Forms flat bar into double-radius S-hooks at one station
- Grooved rotary die supports the bar - no surface marks
- Both hook eyes come out with the same radius
- Straight shank stays true after forming
How Are Markless S-Hooks Bent From Brass Flat Bar?
Short answer: With a hydraulic rotary former and a grooved die that supports the bar through the bend. This video shows flat brass bar being folded into double-radius S-hooks whose polished faces stay free of dents and marks, hook after hook.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Feed | Straight flat bar into grooved die | Correct hook start position |
| Form | Hydraulic rotary former | Smooth first hook radius |
| Repeat | Bar indexed in the same die | Matching second eye, S-shape done |
| Inspect | Hooks turned over in hand | Markless faces, equal radii |
Key Applications
- Display, retail and wardrobe hooks
- Decorative brass and plated hardware
- Hangers and bracket hooks in small batches
- Workshops replacing hand-formed hooks
Rotary Forming vs. Press Folding for Flat Bar Hooks
| Criterion | Press folding | Rotary forming |
|---|---|---|
| Surface marks | Common on polished bar | None with grooved die |
| Hook radius | Angular bend lines | True round eyes |
| Both ends | Re-setup needed | Indexed in one station |
| Part consistency | Varies | Repeatable hook geometry |
FAQ
Will the machine mark polished brass bar? No - the bar rides inside the grooved rotary die during the stroke, so the finished hooks keep clean, markless faces.
Can it run other materials? Yes - the station is set up for flat bar sections; tooling can be matched to steel, copper or plated stock.
Is the operation manual or automatic? Feeding and unloading are manual while the bending stroke is hydraulic, keeping cycles fast and training minimal.
