What Drives Aluminum Case Pricing?
Case dimensions and volume are the largest factors; aluminium panel thickness and hardware grade are next; surface finishing (diamond plate, powder coat, anodising) and interior fit-out (pick-and-pluck foam, EVA inserts, custom trays) add the rest. Tooling for a new shell size runs $500–$2,000 and is a one-time cost credited across repeat orders.
| Criterion | Aluminum case | Plastic / PU case | EVA & PU leather case |
|---|---|---|---|
| Structural rigidity | Highest — aluminum frame results in crushing resistance | Moderate — metal shell can flex | Lowest |
| Weight | Heavier | Lightweight option | Lightest |
| Water and moisture resistance | High with a sealed frame and closed-cell foam lining | Depends on sealing quality | Low to moderate |
| Customising | Full custom, no mould needed for one-off sizes | Limited to existing moulds | Most flexible for soft shapes |
| Tight / high end cost | Mid to high | Lowest once tooling is paid | Mid |
| Branding / embossing | Metal plate and engraving as premium method | Pad printing | Embossing and stitching — retail-friendly |
| Best for | Industrial, military, medical equipment, heavy-duty transport, OEM programs | Consumer transport cases | Retail cosmetic cases and gift boxes |
Conclusion
No single supplier on this list is best for everyone. If you are ordering under 300 units or need a fully custom interior, a factory-direct supplier will usually beat a stock-case distributor on both price and turnaround. If you need cases delivered next week from domestic stock, the US suppliers above are the faster route.
