, it balances the geometric deduction of the sharp corner against the actual material expansion along the neutral axis. 3. Determining the -Factor Table
The DIN 6935 standard provides detailed specifications for the design, dimensions, materials, and testing of these components, ensuring that they meet the required performance and safety standards.
Look up the corresponding factor based on your ratio and bend angle.
) for standard steel, aluminum, and stainless steel sheets based on common bending angles (such as 90∘90 raised to the composed with power 45∘45 raised to the composed with power 60∘60 raised to the composed with power Example: Reference Values for 90∘90 raised to the composed with power For a standard 90∘90 raised to the composed with power
): The shift is minimal, and the K-factor approaches a value of approximately 0.5, meaning the neutral axis rests exactly in the middle of the sheet thickness. Technical Values and Tables Din 6935 Standard Pdf

The standard also outlines how much the final bend can deviate from the design: , it balances the geometric deduction of the
DIN 6935, titled "Cold bending of flat steel products" ("Kaltbiegen von Flacherzeugnissen aus Stahl") , is a standard published by the Deutsches Institut für Normung (German Institute for Standardization).
For mechanical bending, the minimum leg length ( ) is generally recommended to be at least (four times the bending radius). 2. Standard Bending Radii (
Because DIN standards are respected worldwide, a flat pattern calculated via DIN 6935 in Europe will yield the exact same physical part when manufactured in Asia or the Americas. Core Technical Concepts in DIN 6935
) and correction factors to accurately calculate the flat length required to achieve a finished bent component. Look up the corresponding factor based on your
Adhering to the DIN 6935 standard ensures that manufactured parts do not fail during the bending process and that CAD/CAM models perfectly match real-world fabrications. By standardizing the minimum bending radius and k-factors, companies drastically reduce material waste caused by trial-and-error bending. Go to product viewer dialog for this item.
