Airtight 海军舰载箱 from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 50, 12h quote, 30-day delivery to 47 countries.
There is a difference between 'IP-rated' and 'IP-tested'. The first is a marketing claim. The second is a third-party certificate. Our Airtight 海军舰载箱 is the second one.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| 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 |
| WL6030 | 600×450×300 mm | 575×420×280 mm | 4200 g | PP+GF | NVG / Optics Kit |
The most common model for "Airtight 海军舰载箱" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Airtight 海军舰载箱 uses 25 kg/m³ foam rated for 5+ year use. The difference is in the cell structure: 25 kg/m³ cells rebound after compression, 15 kg/m³ cells do not. We have tested both. The cheaper foam fails.
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.
Common equipment we have designed Airtight 海军舰载箱 foam layouts for, based on real customer projects since 2014: DSLR + 2-3 lenses, mirrorless kits, cinema cameras with matte box + monitor, drones (DJI Mavic/Phantom/Inspire) with 5 batteries, broadcast lighting kits, military optics, medical devices.
For Airtight 海军舰载箱: filmmakers should prioritize WL2808-WL5020 with custom foam. Drone operators: WL2005-WL2808 with battery cavities. Broadcast: WL3812-WL5020 with monitor + cable management. Military: WL3812-WL5020 with PP+GF and IP67. Medical: WL1504-WL2808 with anti-microbial foam.
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.
We ship Airtight 海军舰载箱 to 47 countries via FOB Shenzhen, CIF, DDP, EXW. Sea: 12-38 days by region. Express (DHL/FedEx): 3-7 days for samples. Full container load: 28-35 days. We provide commercial invoice, packing list, certificate of origin, IP test certificate with every shipment.
We can show you the test videos. Not the 'demo reel' — the actual SGS or TUV third-party test footage, with date and batch number on it.
Established 2014. 13,000 sqm factory in Fusha Industrial Park, Zhongshan, Guangdong. 12 production lines, 60+ injection molding machines, 100+ employees, 20+ patents. Monthly capacity 80,000 units. Annual export revenue 8M+ USD to 47 countries.
Direct from the OEM.

📹 60-second factory + product walkthrough. Airtight 海军舰载箱 lab test footage: water submersion, drop test, temperature chamber
UV exposure test per ASTM G154: 500 hours accelerated UV exposure (UVA-340 lamp, 60°C). After 500 hours, color shift ΔE < 2.0, no cracking, no chalking. Suitable for outdoor storage and direct sun exposure.
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.
Free 5-day prototyping. ISO 9001 factory-direct. Ships to 47 countries.
