IP67, MIL-STD-810H, ROHS, CE — the alphabet soup on with Trolley Handle robotic-joint-case marketing pages can be overwhelming. This page cuts through the noise. We publish every test result and every certificate we hold.
For your reference, here are the WL series models we typically use for with Trolley Handle robotic-joint-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 |
|---|---|---|---|---|---|
| WL2005 | 195×170×46 mm | 190×135×40 mm | 175 g | PP | Mini Drone |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+GF | DJI Mavic Series |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+GF | DJI Inspire 2/3 |
The most common model for "with Trolley Handle robotic-joint-case" buyers is the WL2005 (195×170×46 mm OD, 175 g empty weight, PP body).
Four components define with Trolley Handle robotic-joint-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 IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -30 ~ +70 °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.
We maintain 200+ foam-cut reference designs for with Trolley Handle robotic-joint-case, covering camera bodies, drone kits, broadcast gear, military equipment, medical devices, and industrial tools. Send us your equipment list, we will match to the closest reference or draft a new layout free within 24 hours.
For with Trolley Handle robotic-joint-case, the decision comes down to: equipment dimensions (always measure with 5-10mm foam clearance), IP rating (IP65 indoor, IP67 outdoor, IP68 water), and certification (FCC for USA, CE for EU, MIL-STD for military). Beyond that, it is foam layout and quantity discount.
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.
We ship with Trolley Handle robotic-joint-case to 47 countries via FOB Shenzhen, CIF, DDP, EXW. Sea: 12-38 days by region. Express (DHL/FedEx): 3-7 days for samples. Full container load: 28-35 days. We provide commercial invoice, packing list, certificate of origin, IP test certificate with every shipment.
Our cases pass MIL-STD-810H Method 516.8 with 26 drops at 1.2m. We can show you the test rig and the post-test inspection photos.

📹 60-second factory + product walkthrough. with Trolley Handle robotic-joint-case lab test footage: water submersion, drop test, temperature chamber
UL94 V-2 standard (self-extinguishing within 30 seconds, no flaming drips). Higher UL94 V-0 rating available for select materials. We do not use materials with toxic flame retardants (Deca-BDE, HBCD) per ROHS.
Resistant to: petroleum products, mineral oil, dilute acids and alkalis, alcohols, and most industrial solvents. Not resistant to: concentrated sulfuric acid, aromatic solvents (benzene, toluene), and prolonged exposure to chlorinated solvents.
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.
