How To Design Parts for Sheet Metal Fabrication

Engineer your parts for seamless manufacturing. Our design guidelines are engineered to prevent common fabrication issues, reduce costs, and accelerate your time-to-market. Adhering to these parameters ensures parts that are not only manufacturable but also robust, reliable, and delivered on schedule.

FeatureRecommended Design Value (MT = Material Thickness)Core Benefit & Consideration
Minimum Bend Radius1×MTPrevents material cracking. Softer materials (e.g., 5052 Al) can go to 0.5×MT; harder ones (e.g., stainless steel) may require ≥2×MT.
Hole-to-Edge Distance≥2×MTPrevents edge tear-out or deformation during punching or laser cutting, ensuring part integrity.
Hole-to-Hole Distance≥2.5×MTMaintains structural strength between holes. Increase to ≥6×MT for high-density patterns or heavy loads.
Bend-to-Hole Distance≥2.5×MTPrevents hole distortion during bending. For tapped or critical holes, increase to ≥4×MT.
Countersink-to-Edge Distance≥3×MTEnsures material integrity around the countersink, preventing breakout and ensuring flush fastener seating.
Minimum Flange Width4×MT (or 6mm)Enables reliable bending. Provides sufficient grip for the press brake die to form a consistent, accurate bend.
Relief Notch Width≥1×MTEliminates material stress and tearing at inside bend intersections, required for perpendicular bends meeting at a corner.
Corner Fillet Radius≥0.5×MTImproves manufacturability and stress distribution. A radius is strongly preferred over a sharp corner for most materials.
