For your reference, here are the WL series models we typically use for Heavy-duty Protective Case Manufacturer applications. Outer dimensions (OD) are measured to the outside of the case; inner dimensions (ID) reflect the usable cavity after subtracting wall thickness. All in millimeters; imperial dimensions in our catalog PDF.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL1204 | 120×90×40 mm | 115×78×32 mm | 100 g | PP | Phone / Wallet |

The most common model for "Heavy-duty Protective Case Manufacturer" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Four components define Heavy-duty Protective Case Manufacturer 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.
Our Heavy-duty Protective Case Manufacturer buyers in 2024 include: 35% camera operators / filmmakers, 25% drone pilots / commercial UAS, 15% broadcast / TV stations, 10% military / law enforcement, 10% medical / first responders, 5% industrial / OEM. Profile data from 2024 buyer survey.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
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.
After Heavy-duty Protective Case Manufacturer ships: (1) We send QC photos before shipment. (2) Lot certificate with serial numbers. (3) 90-day defect replacement. (4) Foam re-cut service for equipment changes. (5) 5-year case body warranty. (6) Tooling stored 3 years for easy reorder.
Our 12h quote turnaround is not a slogan — it is a 12-hour SLA. We respond with model recommendation, FOB/CIF/DDP price, and lead time.
