Capability 06 — Forming
The secret to seamless metal corners. Precision V-grooving and calibrated press-brake bending produce crisp, near-radius-free folds for clean cladding returns, sharp edges and perfectly repeatable angles.
A sharp, clean corner is what separates bespoke metalwork from boxwork — and it's engineered, not improvised.
V-grooving machines a precise groove into the back of a sheet so it folds to a crisp, almost radius-free corner — the trick behind seamless cladding returns and razor-sharp edges.
Press-brake bending forms the rest: calibrated, repeatable folds set by correction angles and verified on the first piece. V-grooved material springs back more than a standard bend, so we compensate deliberately — which is exactly the kind of detail that keeps panels true.
What we do
Two complementary operations — one for the sharpest corners, one for everything else — both calibrated and checked.
A machined groove on the reverse lets the sheet fold to a crisp, near-zero-radius corner for seamless returns and clean edges.
Calibrated forming with correction angles; the angle is measured from the outside and the first piece is verified before the run.
V-grooved material springs back more than standard bends, so we apply larger corrections to land the angle exactly.
Tooling settings and deviations are logged so folds are repeatable across the batch and across projects.
Why it matters
Near-radius-free folds give cladding and boxes the crisp, continuous look of a single piece.
Perfect edge returns on panels and trims — no clumsy radius, no visible seam.
Calibrated correction angles mean every fold matches, panel after panel.
First-piece checks and outside-angle measurement keep geometry accurate.
Long, clean folds across sizeable sheets for facade and feature work.
Controlled forming protects surfaces so the finish stays flawless through to assembly.
How we control it
Crisp, repeatable folds depend on calibration and first-piece verification — both are standard, every run.
The press brake is set with correction angles and logged in a calibration record for traceability.
The bend is measured from the outside (180° minus the reading) for true accuracy.
The first fold is checked before the full run proceeds — no surprises mid-batch.
V-groove springback is anticipated and corrected so the final angle is exact.
Good to know
| Operations | V-grooving for crisp corners; press-brake bending for general forming; press forming for 3D shapes. |
| Materials | Stainless steel SS304 / SS316 and aluminium. |
| Accuracy | Correction angles set and first-piece verified; bends measured from the outside. |
| Springback | V-grooved material requires larger correction angles — anticipated and compensated. |
| Tooling marks | Light pressure marks on the reverse are a natural part of bending; visible faces can be polished on request. |
| Minimum bend | Geometry respects minimum bend and hole rules for the material thickness. |
