Diving Gear 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.

Diving Gear Case how to choose: Product & Manufacturer Overview
Many buyers shop a Diving Gear Case how to choose 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.
The Diving Gear Case how to choose can be tailored to your brand and project: case color, silk-print or laser-engraved logo, foam layout and handle/wheel options are all adjustable. kexinMaterials, as the source factory, runs the whole journey from sample approval to mass production, including neutral shipping and OEM private label.

Standards & Industry Data
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).
IP68 vs IP67 (IEC 60529)
IP68 covers continuous immersion. IEC 60529 does not fix a universal depth or duration — the manufacturer declares conditions that must exceed IP67 (typically 2–10 m). Always request the test certificate to confirm the actual depth/duration rather than relying on the “IP68” label alone.
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.
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 'Diving Gear 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 Diving Gear 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 Diving Gear 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.
