marine-sealed-case manufacturing process from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 100, 12h quote, 25-day delivery to 47 countries.
If you have been burned by a marine-sealed-case manufacturing process supplier before — wrong dimensions, fake IP rating, lead time that doubled mid-order — this page is for you. It is the buyer's guide we wish someone had given us in 2014.
For marine-sealed-case manufacturing process, the WL series splits into Small (WL1204-1504), Medium (WL1905-2808), and Large (WL3812-5020). Within each tier, 2-3 models vary in width and depth. We help you choose during the 12h quote consultation, but the table below is the reference.
| 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 "marine-sealed-case manufacturing process" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
All marine-sealed-case manufacturing process 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 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.
Common equipment we have designed marine-sealed-case manufacturing process 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.
After marine-sealed-case manufacturing process 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.
