Design Guidelines
Optimize your designs for manufacturability with our expert guidelines and feedback, ensuring the best results in Sheet Meatal Fabrication.
Bend Design
2. Avoid sharp bends: Use internal radii to reduce material stress..
3. Bend relief: Provide relief cuts to prevent tearing in tight bends.
Hole Placement and Size
2. Hole edge distance: Maintain a gap of ≥ 2× sheet thickness from edges or bends..
3. Standard hole sizes: Use standard drill bit sizes to minimize custom tooling costs.
Cutout and Slot Design
2. Corner radii for cutouts: Use R ≥ 0.5 mm to reduce stress concentration..
3. Tab and notch clearance: Maintain a minimum gap of ≥ 1 mm for clean cutting.
Tolerances
2. Bending tolerance: ±0.5 mm (depends on material and thickness).
3. Hole placement tolerance: ±0.1 mm for laser cutting.
Flange and Hemming Guidelines
2. Hemming: Used to reinforce edges, reduce sharpness, and improve strength..
3. Hemming gap: Maintain a 0.5 mm clearance for tightly closed hems..
Welding and Joining Considerations
2. Spot welding vs. full welding: Spot welding is faster and preferred for thin sheets.
2. Leave access for welding tools: Ensure joints are easily reachable..
Surface Finishing
2. Anodizing: Corrosion resistance for aluminum..
3. Plating & painting: Additional aesthetic and protective options..
Nesting and Material Utilization
2. Use standard sheet sizes to reduce cutting complexity and cost.
3. Reduce small, intricate features that may be difficult to fabricate..
