CNC Sheet Metal Bending up to 3 meters | Contour
CNC Sheet Metal Bending in Yerevan
We provide precision CNC sheet metal bending, from one-off parts to production quantities. We bend mild steel, stainless steel, aluminium, brass, and copper from your project, 3D model, or dimensioned sketch.
The maximum bending width is 3000 mm.
Accuracy
angle tolerance: ±1°
linear dimensional tolerance: ±0.2 mm
We can make multiple bends in one part, including U-profiles, enclosures, boxes, brackets, and other fabricated components. The feasibility of multiple bends depends on the part’s size and geometry, as well as punch and die clearances, so these parts are reviewed before production. The maximum wall height of box-shaped parts is 70 mm.
Minimum flange height
The minimum flange height depends on the sheet thickness and bending die used:
| Sheet thickness | Minimum flange height |
|---|---|
| up to 1 mm | 6.5 mm |
| up to 1.5 mm | 9 mm |
| up to 2 mm | 11 mm |
| up to 3 mm | 15 mm |
| up to 5 mm | 25 mm |
Thicker sheets can be assessed for bending based on the specific project.
Inside bend radius
The inside bend radius also depends on material thickness and tooling:
up to 1.5 mm sheet: approximately 1.5 mm
2 mm sheet: approximately 2 mm
We can also create large-radius bends from thin sheet when required by the design.
Mirror and decorative sheet finishes
We can bend mirror-finish sheets without leaving bend-line marks. For decorative stainless-steel sheets, please specify the required pattern or grain direction so that every finished part has a consistent surface orientation.
Files to send
The preferred format is a SolidWorks file already designed as a sheet-metal part. This lets us apply the correct bend allowances and achieve the intended final dimensions.
For a simple box, you may send a DXF flat pattern, but we will redesign it in SolidWorks to achieve accurate dimensions and clean corners. Different press brakes and tooling require different corrections, so a DXF flat pattern alone is not always enough.
If you only have a sketch or a 3D model with dimensions, we can prepare the production drawing.
Laser cutting and bending in one workflow
When a part needs both cutting and bending, we first verify and adjust the bending parameters, then laser-cut and bend the part. This ensures the finished component matches the required dimensions.
We also offer welding and finishing for stainless-steel parts. Painting is not performed in-house, but we can discuss arranging it through partners if needed.
Pricing and quotation
Material and quantity are the main cost factors. The number of bends, part complexity, and any additional work also affect the price. A single part generally costs more per unit than a production quantity of the same part.
For a quotation, please send:
a drawing, 3D model, or dimensioned sketch
material and thickness
quantity
surface-finish requirements and grain direction, where relevant
required lead time
If you would like to see a similar completed part, describe what you need and we will check whether we have a saved sample or relevant project.
