Buyers who care about Portable heavy-duty-case certifications usually do so for a reason: their end customer requires it, or their insurance demands it, or their industry standard mandates it. We have shipped to all three.
We do not round dimensions. We do not approximate. Every line in this table is the real catalog data for Portable heavy-duty-case, measured on the production line, with QC sign-off and lot certificate. This is the data we ship with every order.

The most common model for "Portable heavy-duty-case" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Four components define Portable heavy-duty-case protection: shell (PP or PP+GF), foam (25 kg/m³ closed-cell PE), seal (silicone gasket around the lid), and pressure valve (automatic Gore-Tex membrane for IP67/IP68). Each component is tested. Each can be replaced if worn.
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 Portable heavy-duty-case foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries — fits WL2808. (B) DJI Mavic 3 + RC + 4 batteries + charger — fits WL2005. (C) RED Komodo + 2 lenses + monitor + cables — fits WL5020. We share these at the 12h quote stage.
When evaluating Portable heavy-duty-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.

ISO 9001:2015, ROHS, CE, FCC, IP67/IP68, MIL-STD-810H, UN 3480 (LiPo battery transport), WHO PQS pre-qualification (medical), REACH. All renewed annually and available as PDF.
5-stage QC: 100% surface resistance / dimensional check, 26 drops at 1.2m + water submersion, -40 to +80°C × 12 cycles, 5,000 latch cycles, 1,000 pressure valve cycles. Lot certificates traceable by serial number.
Both protect against dust (6 = dust-tight). IP67 = submersible 1m / 30 min. IP68 = submersible beyond 1m (typically 3-5m) / continuous. IP68 costs ~15% more due to reinforced seals and pressure valves.
ASTM B117 standard, 96 hours continuous salt spray (5% NaCl solution at 35°C). After 96 hours, no visible corrosion on metal parts, no delamination of surface coating. Standard for all outdoor-rated models.
UV exposure test per ASTM G154: 500 hours accelerated UV exposure (UVA-340 lamp, 60°C). After 500 hours, color shift ΔE < 2.0, no cracking, no chalking. Suitable for outdoor storage and direct sun exposure.
