Sheet Metal Design Guidelines | China Manufacturing Corp.
Product Details: Sheet metal design involves creating parts that are functional, manufacturable, and cost-effective. Key factors include material selection, bend radii, hole spacing, and tolerances. Design guidelines emphasize avoiding small holes (diameter should be equal to or greater than the sheet thickness), maintaining adequate spacing between holes (at least 2 times the sheet thickness), and ensuring proper bend relief (at least 2T in width and Bend radius + T for Length). Flange width should be at least four times the sheet thickness, and holes should be at a minimum distance of 1.5 times the material’s thickness from bends[1][2][5].

Frequently Asked Questions (FAQs)
Frequently Asked Questions About Sheet Metal Design Guidelines in China
What are the key considerations for material selection in sheet metal fabrication?
When selecting materials for sheet metal fabrication, you need to consider the material’s characteristics, such as its strength, durability, and ease of cutting. For example, aluminum is generally easier to cut than steel, but steel is stronger. You should also think about manufacturability; even if steel can handle the loads, it might not be the best choice if it complicates the manufacturing process.
How do I ensure accurate bending in my sheet metal design?
To ensure accurate bending, you need to pay attention to several parameters. The bend radius should be at least equal to the material thickness to maintain the part’s load-bearing capacity. The bend angle and neutral axis are also crucial. Use the K-factor to calculate the bend allowance, and make sure to include bend lines and specify bend angles and radii in your CAD design.
What are the general tolerances I should follow in sheet metal fabrication?
General tolerances in sheet metal fabrication are important to ensure your parts meet industry standards. For example, bend angles should be within +/- 1 degree, and hole diameters should have a tolerance of +/- 0.005 inches. Offsets and edges to holes or hardware should also be within specific tolerances. These standards help in achieving consistent and high-quality parts.
How should I design corners and edges to avoid stress concentrations?
To avoid stress concentrations, you should use corner fillets and ensure they are symmetrical and uniform throughout the part. The size of the fillet should be at least equal to the thickness of the sheet metal. Placing fillets in areas where the sheet metal is bent or where there is a change in shape can help distribute stress more evenly and prevent potential failures.
What are the best practices for placing features like holes and tabs near bends?
When placing features like holes or tabs near bends, you should follow the 4T rule: keep these features at least 4 times the material thickness away from any bend line. This prevents deformation and ensures the part can be manufactured correctly. Additionally, notches and tabs should be designed with specific dimensions in mind, such as being at least the material’s thickness or a minimum specified length to avoid material breakage.
