Airtight field-command-post-case 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.
IP67, MIL-STD-810H, ROHS, CE — the alphabet soup on Airtight field-command-post-case marketing pages can be overwhelming. This page cuts through the noise. We publish every test result and every certificate we hold.
For your reference, here are the WL series models we typically use for Airtight field-command-post-case applications. Outer dimensions (OD) are measured to the outside of the case; inner dimensions (ID) reflect the usable cavity after subtracting wall thickness. All in millimeters; imperial dimensions in our catalog PDF.
| 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 "Airtight field-command-post-case" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
All Airtight field-command-post-case cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/m³). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
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.
Here are 3 real Airtight field-command-post-case foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries — fits WL2808. (B) DJI Mavic 3 + RC + 4 batteries + charger — fits WL2005. (C) RED Komodo + 2 lenses + monitor + cables — fits WL5020. We share these at the 12h quote stage.
When evaluating Airtight field-command-post-case options, focus on three metrics: (1) Foam density — cheap cases use 15 kg/m³ foam that bottoms out; ours is 25 kg/m³, 5+ year use. (2) Latch cycle rating — cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification — every batch ships with serialized IP test certificates.
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 field-command-post-case 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.
Our cases pass MIL-STD-810H Method 516.8 with 26 drops at 1.2m. We can show you the test rig and the post-test inspection photos.

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.
ROHS 3 (EU 2015/863): compliant for all 10 restricted substances (Pb, Hg, Cd, Cr6+, PBB, PBDE, DEHP, BBP, DBP, DIBP). Third-party test report issued per batch, available as PDF on request.
5-year warranty on case body and latch (covers manufacturing defects, not normal wear). 1-year warranty on foam set (covers material degradation, not mechanical damage). Warranty does not cover misuse, modifications, or cosmetic damage.
PP and PP+GF cases are 100% recyclable. We have a take-back program for end-of-life cases from large customers (1,000+ units / year): we collect, shred, and reuse the regrind in non-critical components.
