Detailed specs for Medium waterproof-case Wholesale from KeXinMaterials source factory. Outer/inner dimensions in mm/inch, weight, material, foam options. Compare WL1204 series. MOQ 100. 12h quote, 25-day delivery.
Choosing Medium waterproof-case Wholesale comes down to three numbers: outer dimensions, inner cavity, and the gear you are protecting. We have been publishing the full WL series spec data since 2014. This page is the complete reference.
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 | Phone / Wallet |
| WL2005 | 195×170×46 mm | 190×135×40 mm | 175 g | PP | Action Camera / GoPro |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP | Diving Mask + Fins |
The most common model for "Medium waterproof-case Wholesale" 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 Medium waterproof-case Wholesale 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 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.
In 2024, we shipped Medium waterproof-case Wholesale for: (1) Film production — ARRI Alexa Mini + accessories in custom foam. (2) Drone operators — DJI Mavic 3 + RC + 6 batteries. (3) Broadcast — RED Komodo + 2 lenses + monitor. (4) Military — rifles + scopes + ammo. (5) Medical — first aid kits + AED.
For Medium waterproof-case Wholesale, the decision comes down to: equipment dimensions (always measure with 5-10mm foam clearance), IP rating (IP65 indoor, IP67 outdoor, IP68 water), and certification (FCC for USA, CE for EU, MIL-STD for military). Beyond that, it is foam layout and quantity discount.
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.
After Medium waterproof-case Wholesale ships: (1) We send QC photos before shipment. (2) Lot certificate with serial numbers. (3) 90-day defect replacement. (4) Foam re-cut service for equipment changes. (5) 5-year case body warranty. (6) Tooling stored 3 years for easy reorder.
We test our cases at the QC station, not at the design office. Every dimension in this page has been measured on a real production batch.
