Stamping wins on per-piece cost at volume when geometry is stable and tooling amortizes. CNC wins when volumes are low, geometry changes often, or tight true-position stacks require machined datums.
Hybrid approaches are common: blanked profile with machined holes or critical faces added in a second operation.
When comparing quotes, align material utilization, tooling NRE, and expected engineering change rates—volume assumptions that ignore ECO frequency can mis-rank processes.
Document assembly interfaces clearly; a bracket that “almost fits” often fails because hole patterns were optimized for one process but validated on another.
