Custom sheet metal bending
Bending turns your laser-cut parts into functional 3D components: enclosures, brackets, angles,
chassis, bent panels. We bend using air bending on a CNC press brake, which
guarantees precise, repeatable angles across the full range of bendable materials.
Each material/thickness combination uses defined tooling (V-die and punch), which means a
fixed inside radius — no custom radii, but consistent results from one production
run to the next. You specify each bend's position, angle (5° to 130° depending on material) and
direction (up or down); our app handles the rest, including the flat pattern calculation with the
correct bend deduction.
Automatic DFM validation
The app automatically checks the feasibility of every bend before you order: minimum flange length,
hole and cutout distance from the bend line, spacing between bends (joggles), bend reliefs,
U-channel ratios, part size. If a bend is a problem, you know right away — no bad surprises after
ordering.
Three ways to add bends
- STEP file (3D): upload your bent part in 3D — the app detects the bends,
unfolds them automatically and keeps angles and directions.
- DXF/DWG file (2D): identify your bend lines in green;
optionally add a text annotation (e.g. "UP 90") to pre-fill the angle and direction.
- Manual drawing: draw the bend line directly in the app on your 2D part,
pick the angle and direction, and preview the result in 3D.
Tapping and hardware insertion are done before bending — keep your holes away from
bend lines (rule: die width ÷ 2) to avoid distortion. All the details are in the
design guide.
