Buyers who care about Lightweight business-trolley-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.
For your reference, here are the WL series models we typically use for Lightweight business-trolley-case 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 |
|---|---|---|---|---|---|
| WL3812-T | 380×320×120 mm | 365×280×110 mm | 1400 g | PP+Aluminum Frame | Sales Rep Kit |
| WL5020-T | 500×400×200 mm | 480×360×185 mm | 3100 g | PP+Aluminum Frame | Trade Show Case |
| WL6030-T | 600×450×300 mm | 575×420×280 mm | 4900 g | PP+Aluminum Frame | Exhibition Display |
The most common model for "Lightweight business-trolley-case" buyers is the WL3812-T (380×320×120 mm OD, 1400 g empty weight, PP+Aluminum Frame body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Lightweight business-trolley-case uses 25 kg/m³ foam rated for 5+ year use. The difference is in the cell structure: 25 kg/m³ cells rebound after compression, 15 kg/m³ cells do not. We have tested both. The cheaper foam fails.
The shell is rated IP54 (splash-resistant, not submersible) ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +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 Lightweight business-trolley-case 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.
For Lightweight business-trolley-case: filmmakers should prioritize WL2808-WL5020 with custom foam. Drone operators: WL2005-WL2808 with battery cavities. Broadcast: WL3812-WL5020 with monitor + cable management. Military: WL3812-WL5020 with PP+GF and IP67. Medical: WL1504-WL2808 with anti-microbial foam.
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 Lightweight business-trolley-case is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (35 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
If a competitor claims IP67 but cannot produce a third-party certificate, ask them why. We always can.

Standard PP case: density 0.91 g/cm³, so yes, all our cases float. Foam-filled case with typical payload (5-30kg equipment): overall density may exceed 1.0, may not float. Specify float requirement and we adjust foam density.
Standard cases: no EMI/RFI shielding. Optional: conductive coating (nickel or copper) on interior surface for EMI shielding per MIL-STD-285. Adds $5-15 per unit depending on size. Used for sensitive electronic equipment.
ROHS 3 (EU 2015/863): compliant for all 10 restricted substances (Pb, Hg, Cd, Cr6+, PBB, PBDE, DEHP, BBP, DBP, DIBP). Third-party test report issued per batch, available as PDF on request.
5-year warranty on case body and latch (covers manufacturing defects, not normal wear). 1-year warranty on foam set (covers material degradation, not mechanical damage). Warranty does not cover misuse, modifications, or cosmetic damage.
PP and PP+GF cases are 100% recyclable. We have a take-back program for end-of-life cases from large customers (1,000+ units / year): we collect, shred, and reuse the regrind in non-critical components.
