Aluminum Frame vs All-Plastic Case
Aluminum frame cases (plastic panels + aluminum edges) and all-plastic cases are two hybrid designs. Aluminum frame offers extra rigidity and premium look. All-plastic is lighter, cheaper, and easier to customize.
Detailed Comparison
| Aspect | Aluminum Frame | All-Plastic |
|---|---|---|
| Weight (530x400x250) | 3-4 kg | 2-2.5 kg |
| Cost | +30-50% | Base |
| Rigid frame | Yes (aluminum edges) | No (all plastic) |
| Premium look | Higher | Standard |
| EMI shielding (frame) | Partial (aluminum frame) | None (unless metalized) |
| Custom panels | Difficult (frame integration) | Easy (molded-in features) |
| Best for | Premium, instruments, military | Standard B2B, OEM |
| Common applications | Instrument cases, test equipment, military | Camera cases, drone cases, OEM |
Verdict
Choose aluminum frame for: premium positioning, instrument transport, military applications. Choose all-plastic for: lower cost, lighter weight, custom features, OEM. Both meet IP67 and Mil-Std-810 in proper design.
Are aluminum frame cases stronger than all-plastic?
Aluminum frame adds rigidity but doesn't dramatically improve drop protection. Both meet Mil-Std-810 if designed properly. The main benefit is premium appearance and EMI partial shielding.
