Skip to contentRobotic Motor Protective Case from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 50, 12h quote, 25-day delivery to 47 countries.
Raw Robotic Motor Protective Case means no specifications yet. You have an equipment list, a use case, a budget, and a deadline. We turn that into a 5-step delivery plan. Here is how.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| 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 |
| WL6030 | 600×450×300 mm | 575×420×280 mm | 4200 g | PP+GF | Drone + Accessories Kit |
The most common model for "Robotic Motor Protective Case" buyers is the WL2005 (195×170×46 mm OD, 175 g empty weight, PP body).
All Robotic Motor Protective Case cases use engineering-grade polypropylene (PP) or PP+glass-fiber composite (PP+GF) for the shell, with CNC-cut closed-cell PE foam inside (density 25 kg/m³). The foam density is calibrated to absorb 1.2m drops on concrete while keeping your equipment from shifting.
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.
In 2024, we shipped Robotic Motor Protective Case for: (1) Film production — ARRI Alexa Mini + accessories in custom foam. (2) Drone operators — DJI Mavic 3 + RC + 6 batteries. (3) Broadcast — RED Komodo + 2 lenses + monitor. (4) Military — rifles + scopes + ammo. (5) Medical — first aid kits + AED.
For Robotic Motor Protective 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 Robotic Motor Protective Case is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (25 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
Raw spec is where we start. We do not push products — we listen first, recommend second.
