Shell material for with Foam Insert marine-sealed-case is selected per use case: standard PP for general purpose, PP+GF for heavy-duty (10% glass fiber improves impact strength by 35%). Foam is 25 kg/m³ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 Ω) available for electronics.
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.
Here are 3 real with Foam Insert marine-sealed-case foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries — fits WL2808.

When evaluating with Foam Insert marine-sealed-case options, focus on three metrics: (1) Foam density — cheap cases use 15 kg/m³ foam that bottoms out; ours is 25 kg/m³, 5+ year use. (2) Latch cycle rating — cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification — every batch ships with serialized IP test certificates.
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.
Ordering with Foam Insert marine-sealed-case is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (25 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
