Still hitting interference when bending deep or large U‑shaped profiles with standard tooling?

This gooseneck upper die + insert‑type single‑V lower die set is designed specifically for press brakes:

✅ Gooseneck upper + single‑V lower – perfect for deep/large U bending – The gooseneck upper die (throat depth 50–150 mm, height 80–200 mm) provides exceptional clearance for tall return fl**ges, while the insert‑type single‑V lower die (V‑opening 20–80 mm, quick‑lock pin insertion) allows instant die changes without unbolting. Together they produce large U‑bends (U‑depth 50–200 mm, opening width 80–300 mm) and deep U‑bends (depth > 150 mm) with zero tool‑to‑workpiece collision – even on parts with up to 120 mm return height.

✅ Perfect collision avoidance for complex geometries – The gooseneck profile retreats away from the bending zone, eliminating interference with previously formed sidewalls. Combined with the insert V‑die's optimized shoulder angle, you can bend U‑shapes where the sidewall height approaches the die width – no re‑tooling, no secondary operations.

✅ Precise, repeatable U‑geometry with zero springback – Springback pre‑compensation (0.5°–1.5°) ensures consistent sidewall angles (±0.3°) and parallel walls (≤ 0.2 mm/m). The insert‑type V‑die provides solid support for thick materials. Suitable for mild steel (≤ 4 mm), stainless steel (≤ 3 mm), aluminum (≤ 5 mm). Finished deep / large U‑profiles are ready for welding, assembly, or further processing – no rework.

Especially suitable for mass production of:
→ Deep U‑channels for industrial racking and structural supports
→ Large U‑bent components for automotive chassis and frames
→ Enclosure side panels with tall return fl**ges
→ Any part requiring deep U‑bending with standard gooseneck + quick‑change single‑V tooling

Still struggling with collision problems when bending closed shapes – square tubes, rectangular frames, or circular rings – on a press brake?

This closed‑profile collision‑avoidance die (square + rectangle + circle + mouth‑shaped) is designed specifically for press brakes:

✅ Closed square, rectangle, circle, and mouth‑shaped profiles – one die set – Forms fully enclosed four‑side frames (square/rectangular: inner opening 50×50 mm up to 500×500 mm, material width 10–80 mm) and complete circular rings (inner diameter 60–400 mm, ring width 10–60 mm) with a special collision‑avoidance die geometry. The relieved punch and retractable forming blocks allow the final closing stroke to complete the shape without hitting already‑bent walls – no tool‑workpiece interference.

✅ Perfect corner closure with zero springback – Optimized multi‑stage forming sequence (pre‑bend three sides → close the fourth side / final curl) with springback pre‑compensation (0.5°–1.5°) ensures the final corner meets seamlessly. Corner gap ≤ 0.3 mm, squareness deviation ≤ 0.5 mm/m, circular roundness tolerance ≤ ±0.5 mm. No rework, no weld‑grinding on the closing corner.

No die change, no secondary press – both features are finished in a single cycle.

✅ Zero springback on both the arc fl**ge and embossed pattern – Optimized die cavity with springback pre‑compensation (0.5°–1.5°) ensures the arc fl**ge holds its true curvature (radius tolerance ≤ ±0.5 mm) and the embossing remains crisp and uniform (depth consistency ≤ ±0.1 mm). Arc fl**ge parallelism ≤ 0.15 mm/m – no rework, no pattern mismatch.

Still swapping dies for 30° flanging, flattening, small offsets, and Z‑steps – across security doors, fire doors, medical doors, elevator doors, and decorative panels?

This composite press brake die (30°+flanging one‑stroke, flattening, small offset, Z‑step) is designed specifically for press brakes:

✅ 30° pre‑flanging + side flanging in one stroke, then flattening – First stage simultaneously creates a 30° angled wall (angle ±1°, height 8–35 mm) and an outward/perpendicular fl**ge (height 5–25 mm) on the same workpiece. Second stage flattens the 30° wall into a closed hem (gap ≤ 0.1 mm, hemming length 6–15 mm). No die change – the 30°‑plus‑fl**ge feature and flattening are completed in one continuous sequence.

✅ Small offset (段差) + Z‑step without repositioning – Following the flattening stage, the same tool set forms a precise small offset (step height 2–10 mm, tolerance ≤ ±0.1 mm) and a parallel Z‑step (step height 3–15 mm, depth 10–40 mm, parallelism ≤ 0.15 mm/m). Springback pre‑compensation (0.5°–1.5° across all stages) ensures true angles on every feature – no rework.

✅ Scratch‑free, coating‑safe for visible door and decorative finishes – Polished 30° cavities, flanging channels, flattening inserts, and Z‑step radii eliminate die marks, scratches, or coating damage. Suitable for galvanized steel, cold‑rolled steel (≤ 1.8 mm), stainless steel (≤ 1.5 mm), pre‑coated decorative sheet (≤ 1.5 mm).

Still worried about multiple die changes and inconsistent results when forming security doors, fire doors, and non‑standard door profiles?

This multi‑operation door forming die (25° fl**ge + Z‑step + offset + flattening + flat-pressing) is designed specifically for press brakes:

✅ Five operations – one tool set, one continuous sequence
Step 1: 25° pre‑flanging (fl**ge height 10–40 mm, angle tolerance ±1°).
Step 2: Z‑step forming (step height 3–15 mm, depth 10–40 mm).

Step 4: Flattening the 25° fl**ge into a closed hem (hemming gap ≤ 0.1 mm).
Step 5: Final flat-pressing to level any distortion (flatness ≤ 0.1 mm/m).
All operations complete without die change or repositioning – the entire door profile is finished in one setup.

✅ Zero springback across all formed features
Independent springback pre‑compensation (0.5°–1.5° for each stage) ensures the 25° fl**ge stays true before flattening, Z‑step retains its shape, and the final hem lays perfectly flat. Angle deviation ≤ ±0.3°, step parallelism ≤ 0.2 mm/m, hemmed edge tightness ≤ 0.1 mm gap – no rework, no secondary pressing.

✅ Scratch‑free, coating‑safe – ready for assembly
Polished forming surfaces and precision flattening inserts eliminate die marks, scratches, or coating damage throughout all five stages. Suitable for galvanized steel, cold‑rolled steel (≤ 1.8 mm), stainless steel (≤ 1.5 mm). Finished security / fire / non‑standard door components (door leaves, frames, side panels) can be directly welded, assembled with core materials, or powder coated – no touch‑up.

Especially suitable for mass production of:
