Detailed specs for Extra Large robotic-joint-case Wholesale from KeXinMaterials source factory. Outer/inner dimensions in mm/inch, weight, material, foam options. Compare WL2005 series. MOQ 50. 12h quote, 25-day delivery.
If you are sourcing Extra Large robotic-joint-case Wholesale from a Chinese factory, you have probably seen marketing sheets with vague dimensions and a single IP rating. We do the opposite. Every dimension here is measured at the QC station, every rating is third-party tested.
For your reference, here are the WL series models we typically use for Extra Large robotic-joint-case Wholesale 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 "Extra Large robotic-joint-case Wholesale" buyers is the WL2005 (195×170×46 mm OD, 175 g empty weight, PP body).
Shell material for Extra Large robotic-joint-case Wholesale 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 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.
Common equipment we have designed Extra Large robotic-joint-case Wholesale foam layouts for, based on real customer projects since 2014: DSLR + 2-3 lenses, mirrorless kits, cinema cameras with matte box + monitor, drones (DJI Mavic/Phantom/Inspire) with 5 batteries, broadcast lighting kits, military optics, medical devices.
Cheap Extra Large robotic-joint-case Wholesale: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our Extra Large robotic-joint-case Wholesale: $5-15/unit, 10-year lifespan, 5,000-cycle latch, 25 kg/m³ foam. Over 5 years, our case is 4-5x cheaper per year of use. Total cost of ownership wins.
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 Extra Large robotic-joint-case Wholesale 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 spec sheets include the manufacturing tolerance, not just the nominal value. That is what real engineers ask for.
Established 2014. 13,000 sqm factory in Fusha Industrial Park, Shenzhen, Guangdong. 12 production lines, 60+ injection molding machines, 100+ employees, 20+ patents. Monthly capacity 80,000 units. Annual export revenue 8M+ USD to 47 countries.
Direct from the OEM. Unlike trading companies or sourcing agents who add 15–40% markup and disappear after delivery, KeXinMaterials handles everything in-house: mold development, injection molding, foam CNC cutting, QC testing, export documentation. Our 2024 buyer survey showed 87% repeat-order rate and 0.3% defect rate across 47 countries.
