Points Sheet Metal Customers Should Know When Designing Drawings

Design Considerations for Sheet Metal Fabrication:

  • Wall Thickness: Uniform thickness is very important for any geometry. Geometries with more than one wall thickness will require sheet metals of different thicknesses. Therefore, the alignment and orientation of parts may be inaccurate or take time.
  • Bend Radii: It is important to keep the inside bend radius of sheet metal at least equal to its thickness. This will help to avoid distortions and fractions in the final parts. Maintaining the bend radii consistently across the part ensures cost-effectiveness and good orientation.
  • Bend Allowance and Deduction: Bend allowance is the material needed to be added to the actual lengths of the parts to help develop a flat pattern. Bend deduction is the material needed to be removed from the length of flanges to help get a flat pattern.
  • K Factor: K factor is the sheet metal process is the ratio of neutral axis to material thickness. This value changes with respect to the various physical properties and thickness of materials used.
  • Holes and Slots Orientation: These factors are also very important. Holes and slots diameter should at least be as large as the thickness of the sheet metal. Also, holes should be reasonably spaced. They should never be too close to the edge of the material.

Currently, our non-standard sheet metal fabrication parts are exported to America, Canada, Australia, United Kingdom, Germany, France, Sout Africa, and many other countries all over the world. We are ISO9001-2015 registered and also certified by SGS.
