There are 5 common mistakes buyers make when sourcing small-protective-case certification process. We see them every week. This page covers all of them, with the data to back it up.
For your reference, here are the WL series models we typically use for small-protective-case certification process 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 | Phone / Wallet |
| WL2005 | 195×170×46 mm | 190×135×40 mm | 175 g | PP | Action Camera / GoPro |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP | Kayak / Fishing Gear |
The most common model for "small-protective-case certification process" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Shell material for small-protective-case certification process 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 IP68 (submersible 5m / 30 min) ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -30 ~ +80 °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 small-protective-case certification process 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.
For small-protective-case certification process: 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.
Standard small-protective-case certification process: MOQ 100 units, 25-day production, T/T 30/70. Custom: MOQ 500 units, 25-30 days mold + 25 days production. We support L/C for >$20,000 orders. Sample lead time 5-7 days, sample cost refundable on >2,000 unit order.
