9. Cost Considerations

Stamping small parts often incurs higher per part costs compared to stamping larger parts. This is primarily driven by the higher tooling costs required for stamping small parts. The stamping dies and supporting tooling involved in metal stamping have high fixed costs regardless of part size. But with small parts, the production volumes are usually lower, so the fixed tooling costs get spread across fewer parts.

In addition, because small parts are more intricate and complex, the tooling itself tends to be more sophisticated and expensive. This further increases the fixed costs that have to be accounted for. The more detailed the part geometry, the more complex the die components need to be.

Moreover, small parts often require secondary processing after stamping, such as deburring, cleaning, heat treatment, plating, etc. And the cost of these secondary operations on a per part basis is higher with lower volumes.

The combined effect is that small part stamping results in a higher per piece cost compared to high volume production of larger, less intricate parts. Therefore, cost reduction strategies need to be explored. This includes investigating alternative materials, engineering the parts for easier processing, tooling optimization, lean manufacturing techniques, and increasing volumes whenever possible. Getting the lowest possible cost per part requires addressing the cost drivers throughout the entire stamping process chain.

10. Quality Control

Controlling quality is always important in metal stamping, but can be especially challenging with small parts. The small size makes effective inspection more difficult, as tiny defects are harder to detect visually. At high production volumes, manual inspection becomes impractical. Small parts may require specialized inspection equipment like optical comparators, vision inspection systems, or automated sorting machines.

If using automated systems, the fixturing and handling of tiny parts presents difficulties. Parts can shift during inspection, producing false rejects. Cleanliness is also critical, as any debris or dust can obscure defects in small features. And with less material, small parts are more prone to accidental damage during handling between processes.

Stamping shops need robust quality control plans for small parts, with well-designed inspection points, gauging, and sample sizes. Issues like burrs, flash, warped or bent parts, and coating flaws become major defects on miniature components. And when problems arise, root cause analysis is essential to identify and correct the source rather than just scrapping parts. Proactive process monitoring and control techniques are key to minimizing defects and maintaining tight tolerances when stamping small metal parts.
