Foam Insert Submersible Case is an engineered protective case in the waterproof case family: built by source factory kexinMaterials with IP67 sealing, impact-resistant PP copolymer or rotomolded PE shells and CNC-cut custom foam; wholesale, OEM and export supported.
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.
Foam Insert Submersible Case: Product & Manufacturer Overview
For buyers, the true cost of a Foam Insert Submersible Case is more than unit price: carton specs shape freight, and spare parts and replenishment shape long-term use. kexinMaterials optimizes container loading and ships wear-part kits with volume orders to lower your total cost of ownership.
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.
Key Specifications

Product Feature Breakdown
Three insert processes dominate for Foam Insert Submersible Case: pick-and-pluck foam (low cost, coarse), CNC-routed EVA/PU (±1 mm, repeatable in batches) and vacuum-formed or compression-moulded liners (lowest unit cost at volume, requires tooling). kexinMaterials recommends the route from your volume and tolerance needs.
How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|

| 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 |
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.
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
Product Overview
The kexinMaterials Foam Insert Submersible Case is one-piece molded from engineering plastics, balancing impact strength, sealing and long-term durability — available from stock or fully customized. Key specs below.
On process: the Foam Insert Submersible Case can be injection, rotational or blow molded. Injection gives precise sealing and repeatability; rotomolding yields large seamless shells with thick-wall toughness; blow molding suits light, economical builds. kexinMaterials runs all three lines and matches the process to your protection grade and budget.
For interior protection, the Foam Insert Submersible Case ships with or accepts CNC-cut EVA/PE foam, routed to your equipment's 3D data so nothing shifts in transit; precision instruments can add ESD-safe or cushioned layered structures.
On quality, the Foam Insert Submersible Case passes batch drop, stack and immersion checks; key models can be tested to MIL-STD-810H for drop and vibration, with material and third-party test reports supplied for export and industry acceptance.
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.
