There is a difference between 'IP-rated' and 'IP-tested'. The first is a marketing claim. The second is a third-party certificate. Our High-strength 空投箱 is the second one.
We do not round dimensions. We do not approximate. Every line in this table is the real catalog data for High-strength 空投箱, measured on the production line, with QC sign-off and lot certificate. This is the data we ship with every order.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL1204 | 120×90×40 mm | 115×78×32 mm | 100 g | PP | Pistol Case |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+GF | Rifle Case |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+GF | Multi-Rifle Kit |
The most common model for "High-strength 空投箱" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Four components define High-strength 空投箱 protection: shell (PP or PP+GF), foam (25 kg/m³ closed-cell PE), seal (silicone gasket around the lid), and pressure valve (automatic Gore-Tex membrane for IP67/IP68). Each component is tested. Each can be replaced if worn.
The shell is rated IP67 + MIL-STD-810H ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -50 ~ +90 °C. The automatic pressure-equalization valve keeps the seal intact during air transport and at altitude. Latch is a double-throw design rated for 5,000 open/close cycles. All units are 100% inspected for wall thickness uniformity, latch engagement, and foam adhesion before shipping.
We maintain 200+ foam-cut reference designs for High-strength 空投箱, covering camera bodies, drone kits, broadcast gear, military equipment, medical devices, and industrial tools. Send us your equipment list, we will match to the closest reference or draft a new layout free within 24 hours.
Cheap High-strength 空投箱: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our High-strength 空投箱: $5-15/unit, 10-year lifespan, 5,000-cycle latch, 25 kg/m³ foam. Over 5 years, our case is 4-5x cheaper per year of use. Total cost of ownership wins.
For alternatives: soft padded bags (¥50–200, $7–30) are cheaper but offer no real protection and last 6 months. Aluminum hard cases ($80–300) are heavier, prone to denting, and 2–4× the price. Carbon fiber cases ($300+) are overkill for 95% of B2B use cases. Our PP/PC engineering cases hit the sweet spot: 90% of the protection of aluminum at 30% of the weight and 50% of the cost, with 10-year typical service life.
After High-strength 空投箱 ships: (1) We send QC photos before shipment. (2) Lot certificate with serial numbers. (3) 90-day defect replacement. (4) Foam re-cut service for equipment changes. (5) 5-year case body warranty. (6) Tooling stored 3 years for easy reorder.
Every certificate we publish is dated and serialized. We do not stock certificates — we issue them per batch.

Anti-static foam option: surface resistance 10^6 to 10^11 Ω per ANSI/ESD S541. Standard foam is non-ESD. If you are transporting electronics (camera bodies, circuit boards, hard drives), specify anti-static foam.
UL94 V-2 standard (self-extinguishing within 30 seconds, no flaming drips). Higher UL94 V-0 rating available for select materials. We do not use materials with toxic flame retardants (Deca-BDE, HBCD) per ROHS.
Resistant to: petroleum products, mineral oil, dilute acids and alkalis, alcohols, and most industrial solvents. Not resistant to: concentrated sulfuric acid, aromatic solvents (benzene, toluene), and prolonged exposure to chlorinated solvents.
Standard PP case: density 0.91 g/cm³, so yes, all our cases float. Foam-filled case with typical payload (5-30kg equipment): overall density may exceed 1.0, may not float. Specify float requirement and we adjust foam density.
Standard cases: no EMI/RFI shielding. Optional: conductive coating (nickel or copper) on interior surface for EMI shielding per MIL-STD-285. Adds $5-15 per unit depending on size. Used for sensitive electronic equipment.
