How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|
| Wheels | Heavy-duty casters + aluminium trolley, loaded drag | Cheap wheels fail |
| Shell | ABS/PP composite, stack-resistant | Single resin deforms |

| MOQ | From 50 pcs, size custom | Few stock sizes |
| Use | Film/expo/inspection mobility proven | Lacks proof |
Waterproofing: rated IP67 — fully dust-tight and leak-free after 30 minutes at 1 m depth. Sealing relies on a continuous silicone gasket in a molded rim channel, plus an automatic pressure valve so the case opens normally after rapid pressure changes.
Standards & Industry Data
Shell Materials Compared (PP / ABS / PE)
Industry data puts PP (polypropylene) at ~55% of plastic protective-case share — strong chemical resistance, low-temperature toughness and cost efficiency; ABS holds ~30% with harder, glossier surfaces; large thick-wall cases favor rotomolded PE. Plastic/polymer cases together account for 63.7% of the industrial protective case market (2025).
Foam Inserts (EVA / PU / XLPE)
Three insert materials dominate: EVA (closed-cell, waterproof, firm support for precision instruments), PU foam (open-cell, soft cushioning, economical) and XLPE (chemically inert, non-shedding — preferred for medical and optics). CNC pockets are cut from the equipment's 3D data; drawing-to-first-sample typically takes 1–2 weeks.
Military Drop Test (MIL-STD-810H, Method 516.8 Proc. IV)
MIL-STD-810H (8th revision, 2019; 29 test methods) requires transit-drop samples to survive 26 drops from up to 5 ft (1.5 m) onto steel-backed concrete in varied orientations. Versus 810G, the H revision raised drop height from 4 ft to 5 ft and switched to a harder steel-backed surface.
Typical Applications
- Field-service engineer tool kits
- Sales sample presentation cases
- Medical device field visits
- Utility and telecom field equipment
- Corporate gifts and staff kits
- Business travel equipment carry
