What is 空投箱 which is cheap, really? The term gets used loosely in the B2B protective case market. Here is the precise definition, what it includes, and what it does not.
For your reference, here are the WL series models we typically use for 空投箱 which is cheap 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 "空投箱 which is cheap" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Shell material for 空投箱 which is cheap is selected per use case: standard PP for general purpose, PP+GF for heavy-duty (10% glass fiber improves impact strength by 35%). Foam is 25 kg/m³ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 Ω) available for electronics.
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.

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.

Step 1: Define your equipment's outer dimensions (L×W×H in mm). Step 2: Add 5-10mm clearance for foam thickness. Step 3: Match to WL series: WL1204 → WL2005 → WL2808 → WL3812 → WL5020. Step 4: Confirm IP rating (IP65 indoor, IP67/IP68 outdoor/water). Step 5: Send spec for 12h quote.
Top 5 mistakes: (1) Choosing by price alone, ignoring that cheap cases skip IP certification. (2) Over-specifying size — buying WL5020 when WL3812 fits. (3) Ignoring latch type — 200-cycle vs 5,000-cycle. (4) Forgetting pressure valve for air travel. (5) Not requesting lot certificates.
