Design Element | Suggestions (Industry Standard Values) | Reasons and Benefits |
---|
Material Thickness | Recommended range: 0.2 - 6 mm (typical: 0.5 - 3 mm) | Ensures efficient forming, reduces tool wear, and optimizes part quality. |
Corner Radii | Minimum radius ≥ 0.5 - 1x material thickness | Prevents cracking, reduces stress concentration, and improves durability. |
Minimum Hole Diameter | Minimum diameter ≥ 1.2x material thickness | Prevents tool damage, distortion, and ensures reliable stamping operations. |
Hole Spacing | Minimum spacing ≥ 2x material thickness | Maintains structural integrity, avoids deformation or distortion. |
Edge-to-Hole Distance | Minimum distance ≥ 1.5 - 2x material thickness | Prevents edge deformation, tearing, and ensures dimensional accuracy. |
Bend Radius | Minimum bend radius ≥ 1x material thickness | Reduces the risk of cracking, ensures consistent forming, and improves strength. |
Bend-to-Hole Distance | Minimum distance ≥ 2x material thickness | Prevents hole deformation during bending, ensuring dimensional accuracy. |
Flange Width | Minimum flange width ≥ 2.5 - 3x material thickness | Ensures adequate support and stable forming, reducing tooling issues. |
Tolerances | Typical dimensional tolerance: ±0.1 - 0.25 mm | Achievable stamping accuracy, balancing precision, quality, and cost. |
Draft Angles | Typically 0.5° - 1° per side (if applicable) | Facilitates part ejection from die, reduces tooling wear, improves productivity. |
Deep Draw Depth | Maximum depth ≤ 2.5x part diameter per draw | Prevents excessive material thinning, tearing, or wrinkling during drawing operations. |
Relief Cuts | Use relief cuts near complex bends or corners | Reduces stress concentration, tearing risks, and facilitates smooth forming. |
Text and Logos | Minimum height ≥ 1.5 - 2 mm, positioned on flat areas | Ensures clear, legible text without distortion due to stamping operations. |
