8-Series Aluminium Frame Cases: Engineered for Mission-Critical Protection
8-series aluminium frame cases from Kexin: 57 models, IP67/IP68, MIL-STD-810H tested. For defense, aerospace, medical, and high-end B2B. Custom foam, Pantone, 500-piece MOQ, EXW Guangdong / FOB Shenzhen.
Direct answer: Kexin 8-series aluminium frame cases are 57 rugged models engineered for defense, aerospace, medical, and high-end B2B applications. They pass IP67/IP68 waterproof tests, MIL-STD-810H 26-drop tests, and -40°C to +80°C temperature range. The aluminium frame adds 30% more rigidity vs. standard ABS cases while keeping weight competitive. MOQ starts at 500 pieces with 4-6 week lead time for ODM, 12-16 weeks for OEM. Pricing: USD 18-180 per piece FOB Shenzhen depending on size and foam configuration.
What Makes Aluminium Frame Cases Different?
An aluminium frame case uses extruded aluminium profiles bonded to the case body — typically along the lid seam and hinge side. The frame provides three structural advantages over all-plastic cases:
- 30-40% higher rigidity under vertical load (a 50kg stack on the case lid does not flex)
- Better drop performance — frame absorbs and distributes impact energy, reducing crack risk at corners and latches
- Improved temperature stability — aluminium has lower thermal expansion than PP/ABS, so the seal stays tight from -40°C to +80°C
Trade-off: aluminium frame cases weigh 10-15% more than comparable all-plastic cases. For applications where every gram matters (drone transport, mobile medical kits), 6-series or 7-series may be a better fit.
