Dry Box manufacturing process — short answer: judge three things: ingress protection (IP67 = 1 m for 30 min), impact structure (26-drop military testing) and foam fit (EVA/PU/XLPE by payload). Details below, standard by standard.
A waterproof case uses a silicone gasket and latches to achieve IP67 dust-tight and watertight protection, suited to marine, outdoor and rescue use where gear must stay dry after brief immersion.
Frequently Asked Questions

Dry Box manufacturing process: Product & Manufacturer Overview
A Dry Box manufacturing process exists so your valuable gear ignores rain, immersion and dust. The kexinMaterials waterproof range starts at IP67, built on full-perimeter silicone seals and dual latch closure, serving outdoor sports, expedition photography, marine fishing and emergency response.
Many buyers shop a Dry Box manufacturing process on the word 'waterproof' alone, but reliability actually lives in the seal architecture and pressure management. kexinMaterials molds a continuous silicone gasket channel into the rim and adds an automatic relief valve, so the case opens easily after altitude or air-freight pressure swings while staying watertight.

How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|
| Rating | IP67 standard, IP68/IPX6 optional | Splash-only, floods when immersed |
| Sealing | Silicone gasket + auto pressure-equalization valve | No valve, collapses at altitude |
| Weathering | UV-stable modified PP, salt-fog resistant | Generic resin yellows outdoors |
| Latches | Waterproof latches with rubber gasket | Plain clasps leak |
| MOQ | From 50 pcs, custom colors | High batch barrier |
| Proven use | Marine/diving/fishing field cases | Lacks scenario proof |
Moisture control: the sealed shell pairs with a desiccant chamber and humidity indicator to hold interior humidity in a safe band — suited to humid seasons and ocean freight.
Standards & Industry Data
Water-Jet Tests (IPX5/IPX6)
IPX5 uses a 6.3 mm nozzle at 12.5 L/min from 3 m for at least 3 minutes (~30 kPa); IPX6 steps up to a 12.5 mm nozzle at 100 L/min (~100 kPa), simulating sea waves and pressure washing. Marine and outdoor cases should meet at least IPX6.
Extreme Temperature Performance
Engineering-grade cases typically operate from -30°C to +80°C (military testing follows MIL-STD-810H Methods 501.7/502.7 for temperature and 503.7 for thermal shock, cycling as wide as -40°C↔+71°C). For cold climates choose PP copolymer or PE shells — standard ABS embrittles at low temperatures.
IP Ratings (IEC 60529)
In IP67, the “6” means dust-tight (no dust ingress after a 2 kPa vacuum dust test) and the “7” means temporary immersion: the enclosure survives 30 minutes at 1 m depth with its highest point at least 150 mm below the surface, per IEC 60529 Clause 14.2.7.
Typical Applications
- Overlanding and expedition gear storage
- Marine fishing and boat equipment
- Photography gear in the field
- Emergency-response equipment staging
- Water sports and dive gear transport
- Utility line-inspection tool carry
Buying Questions Answered
For 'Dry Box manufacturing process', the FAQ below gathers what buyers ask most — price structure, MOQ, customization flow and lead time — to speed up your sourcing decision.
When comparing Dry Box manufacturing process suppliers, weigh four things: shell material and wall thickness, seal design and verified ingress rating, interior-foam capability, and whether the factory owns tooling and QC in-house — these decide long-term reliability.
Before sourcing a Dry Box manufacturing process, note the payload's largest dimensions, single-unit weight and shipping mode (air/land/sea). Send those to kexinMaterials and you get a matched case recommendation and quote fastest.
Manufacturing Process
The whole range is high-pressure injection molded with gasket-channel tolerances held to the 0.1 mm class. Each batch is sample-tested with a 1-meter, 30-minute immersion to keep IP67 performance consistent.



Field Case Studies
