Sheet Metal Design Guidelines
Designing for manufacturability reduces costs, improves quality, and accelerates lead times. Our engineering team reviews every project for DFM optimization—but these guidelines help you create production-ready designs from the start.
Bend Radii
Minimum inside bend radius should equal material thickness for steel, 1.5× for aluminum to prevent cracking.
Hole-to-Edge Distance
Maintain minimum distance from hole edge to bend line to prevent distortion during forming.
Hole-to-Hole Spacing
Minimum spacing between holes prevents material deformation and ensures punch tool clearance.
Flange Height
Minimum flange height ensures proper forming without material tearing or springback issues.
Feature Proximity
Keep features (holes, slots, tabs) away from bends to maintain dimensional accuracy.
General Tolerances
Standard tolerances for laser cutting, bending, and assembled dimensions.
Standard Manufacturing Tolerances
The table below reflects our standard and precision capabilities. Standard tolerances apply unless tighter values are specified on your drawing. Tighter tolerances may increase cost and lead time — specify them only on functionally critical dimensions.
| Feature / Process | Standard Tolerance | Precision (on request) | Notes |
|---|---|---|---|
| Laser cutting — linear | ± 0.10 mm | ± 0.05 mm | For material thickness ≤ 3 mm |
| Laser cutting — hole diameter | ± 0.10 mm | ± 0.05 mm | Holes < 1 mm not recommended for laser |
| CNC punching — hole position | ± 0.10 mm | ± 0.05 mm | Relative to datum |
| Bending — angle | ± 0.5° | ± 0.25° | Springback varies with material and thickness |
| Bending — flange length | ± 0.20 mm | ± 0.10 mm | Measured from bend line to edge |
| Overall dimensions (< 300 mm) | ± 0.20 mm | ± 0.10 mm | Cumulative tolerance applies for multi-bend parts |
| Overall dimensions (300–1000 mm) | ± 0.30 mm | ± 0.15 mm | Use datum references for critical fits |
| Overall dimensions (> 1000 mm) | ± 0.50 mm | ± 0.25 mm | Large parts may require fixture verification |
| Flatness | 0.5 mm / 300 mm | 0.2 mm / 300 mm | After leveling; thin sheets may require fixturing |
| Hardware insertion position | ± 0.15 mm | ± 0.08 mm | PEM / clinch nuts, studs, standoffs |
| Welding distortion | ± 0.3–0.5 mm | ± 0.15 mm | Precision achievable with fixtures and laser welding |
| Powder coat thickness | 60–80 μm | 40–120 μm range | Adjustable per specification |
