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).
