When holes, bends, or embosses sit too close together, the forming quality drops quickly. The metal cannot stretch evenly, which leads to cracks, wrinkles, or distorted shapes. These issues increase scrap, wear out tools faster, and slow down production. Most of the time, the cause is poor spacing in the design stage.<\/p>

Reliable forming starts with proper spacing. Maintaining sufficient distance between features allows the metal to flow freely. It reduces stress and helps maintain consistent part geometry. Good spacing also protects tooling, improves repeatability, and lowers production costs.<\/p>

Designing with the correct spacing makes the difference between a smooth process and a risky one. Let’s look at how proximity works and why it matters in every sheet metal design.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Fundamentals of Feature Proximity in Sheet Metal Design<\/h2>

<\/p>

Feature proximity means the distance between features such as holes, bends, embosses, or cutouts on a sheet metal part. This distance directly affects how the material behaves during forming. When features are too close together, stress builds up, leading to cracks or uneven stretching.<\/p>

<\/p>

Definition and Function<\/h3>

<\/p>

Feature proximity controls mechanical stability. Proper spacing keeps the part strong and reduces distortion. For example, if two holes are too close to a bend<\/a>, both pull from the same area of material during forming. This can cause tearing or elongation around the holes. With correct spacing, each forming step happens without interference.<\/p>

Influence of Material Properties<\/h3>

<\/p>

Material properties determine how far apart features should be spaced.<\/p>
