Dustproof Case how to choose — 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
Can I stand or sit on the case?
Does salt water corrode the case or hardware?
Can a waterproof case stay submerged for a long time?
Do gaskets age, and can they be replaced?
Can these cases ship dangerous goods or chemicals?
Will sun exposure fade or embrittle the shell?
Dustproof Case how to choose: Product & Manufacturer Overview
kexinMaterials is a factory-direct waterproof case manufacturer in Guangdong with self-developed tooling, covering sizes from 10-inch personal cases to 50-inch equipment trunks — colors, interiors and logos all customizable for wholesale and OEM programs.
Outdoor work demands waterproofing, crush resistance and buoyancy margin in one shell. kexinMaterials cases offer positive buoyancy references under rated loads, lockable latches and shoulder systems for on-water operations and island logistics.

Standards & Industry Data
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.
Shell Materials Compared (PP / ABS / PE)
Industry data puts PP (polypropylene) at ~55% of plastic protective-case share — strong chemical resistance, low-temperature toughness and cost efficiency; ABS holds ~30% with harder, glossier surfaces; large thick-wall cases favor rotomolded PE. Plastic/polymer cases together account for 63.7% of the industrial protective case market (2025).
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 'Dustproof Case how to choose', the FAQ below gathers what buyers ask most — price structure, MOQ, customization flow and lead time — to speed up your sourcing decision.
When comparing Dustproof Case how to choose 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 Dustproof Case how to choose, 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
2,000 marine equipment cases, IP68 + UV-stable, no aging or leakage after 18 months in salt spray.
900 dive-gear cases with pressure-equalization valves, no collapse during high-altitude transit.
