Explosion-proof 空投箱 Manufacturer 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.
If you searched for Explosion-proof 空投箱 Manufacturer, you probably have a specific use case in mind — not the generic 'protective case'. We have built 150+ custom variations since 2014. Here is what we know.
For your reference, here are the WL series models we typically use for Explosion-proof 空投箱 Manufacturer 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 |
| WL8040 | 800×500×400 mm | 770×470×370 mm | 7800 g | PP+GF | Weapons & Ammo Pack |
The most common model for "Explosion-proof 空投箱 Manufacturer" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
All Explosion-proof 空投箱 Manufacturer 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.
Common equipment we have designed Explosion-proof 空投箱 Manufacturer 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.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
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.
