Plan the Part Before You Cut or Bend
A practical sheet metal workflow starts with design review, not tooling. Confirm the material grade, thickness, and finish requirements so the part can survive handling, vibration, and corrosion exposure. If you have tolerances for critical interfaces, Sheet Metal Fabrication specify them early and avoid relying on “bend cleanup” to fix design gaps. A quick manufacturability check can prevent costly rework when the flat pattern doesn’t match what your assembly needs.
Next, map the part’s forming sequence and identify features that can interfere with dies, clamps, or press access. Consider bend allowance, bend radius, and bend direction so the final geometry lands where it should. For holes, slots, and tabs, validate spacing from edges and from bend lines to reduce distortion and tearing. When you align design decisions with real shop capabilities, you get stable results across prototypes, pilot runs, and repeat production.
Choose the Right Forming Process and Tooling
Metal bending can be achieved with multiple methods, and the best choice depends on material behavior and desired accuracy. For many applications, press braking offers flexibility for custom parts and moderate volumes. Air bending, bottom bending, and Metal Bending coining each influence springback and surface finish, so the process selection should match your tolerance targets. If tight angles are required, plan for compensation by adjusting tooling or using controlled forming parameters.
