Sheet Metal Bending Tolerances
The following table provides general information concerning BZ Metal Products' sheet metal bending tolerances. For more specific information or custom requirements, please contact our engineering team.
| Description | General Tolerance |
|---|---|
| Bend Angle Tolerance | ±1° (Standard) / ±0.5° (Precision) |
| Bend Radius Tolerance | ±0.010" for material up to 0.100" thick |
| Flange Length Tolerance | ±0.015" for dimensions up to 12" |
| Minimum Flange Length | Material thickness x 2 (minimum 0.125") |
| Minimum Inside Bend Radius | 1T for aluminum, 1.5T for steel (T = material thickness) |
| Hole to Bend Distance | Minimum 2T + bend radius (T = material thickness) |
Design Guide: Sheet Metal Bending
Designing parts for sheet metal bending requires understanding certain principles to ensure manufacturability, accuracy, and cost-effectiveness. Our comprehensive guide will help you optimize your designs for the bending process.
Key Design Considerations:
- Maintain a minimum flange length of 2x material thickness
- Keep holes and cutouts at least 2x material thickness plus bend radius away from bends
- Consider grain direction for materials where it affects bendability
- Account for bend allowance and bend deduction in your flat pattern designs
- Design reliefs at corners where bends intersect to prevent material tearing
- Avoid small, intricate features near bend lines

-
What is the minimum bend radius you can achieve?
The minimum bend radius depends on the material type and thickness. As a general rule, we can achieve a bend radius as small as 1x material thickness for aluminum and 1.5x material thickness for steel. For precise information about your specific material, please contact our engineering team.
-
What is the maximum thickness you can bend?
With our CNC press brakes capable of up to 350 tons of pressure, we can bend mild steel up to 0.75" (19mm) thick, stainless steel up to 0.5" (12.7mm) thick, and aluminum up to 0.625" (16mm) thick. These values may vary based on the specific material grade and bend length.
-
How do you account for springback during bending?
Springback occurs when material elastically returns slightly after bending. Our CNC press brakes have advanced compensation capabilities that automatically adjust for springback based on material properties. For critical applications, we perform test bends to fine-tune our process parameters and ensure dimensional accuracy.
-
Can you bend pre-finished or coated materials?
Yes, we can bend pre-finished, painted, or coated materials. We use special tooling and techniques to minimize damage to the finish. However, some cracking or minor damage may occur at the bend area depending on the coating type and the bend radius. We recommend discussing your specific requirements with our team to determine the best approach.
-
What file formats do you accept for quote requests?
We accept a variety of 3D and 2D file formats including STEP, STP, SLDPRT, DXF, IPT, PRT, and SAT files. For optimal results, we recommend providing both the 3D model of the final part and the 2D flat pattern drawing with bend lines clearly indicated.
