Process selection is the single biggest cost driver in custom metal parts. Whether you choose sheet metal fabrication or stamping — or CNC machining over welding — the decision changes your tooling investment, lead time, tolerance capability, and unit price by an order of magnitude. These manufacturing guides break down each process comparison with breakeven volume analysis, tooling cost models, tolerance ranges, and DFM tradeoffs, so procurement and engineering teams can lock in the right process before committing to a supplier. From low-volume prototyping with zero tooling to high-volume production with progressive dies, matching the process to your part geometry and annual quantity is the first step to controlling total landed cost.
