UV-resistant vehicle-warmer-case from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 30, 12h quote, 35-day delivery to 47 countries.
Most UV-resistant vehicle-warmer-case marketing claims do not survive a real-world drop test. Our cases do — because we test every batch to the same standard we publish, not to a 'design intent'.
For your reference, here are the WL series models we typically use for UV-resistant vehicle-warmer-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 |
|---|---|---|---|---|---|
| WL2305 | 230×180×45 mm | 225×150×40 mm | 240 g | PP+PC | First Aid Kit |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+PC | Vaccine Carrier |
| WL5020-C | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+PC+PCM | Cold Chain 24h (-20°C) |
The most common model for "UV-resistant vehicle-warmer-case" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
UV-resistant vehicle-warmer-case shells are rated -40°C to +80°C per MIL-STD-810H Method 501.7 (high) and 502.7 (low). Chemically resistant to petroleum, mineral oil, dilute acids, alcohols, and most industrial solvents. Not resistant to concentrated sulfuric acid, aromatic, or chlorinated solvents.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -80 ~ +50 (depending on PCM/VIP configuration) °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.
Here are 3 real UV-resistant vehicle-warmer-case foam layouts from 2024-2026: (A) Sony A7 IV + 24-70mm + 70-200mm + 3 filters + 2 batteries — fits WL2808. (B) DJI Mavic 3 + RC + 4 batteries + charger — fits WL2005. (C) RED Komodo + 2 lenses + monitor + cables — fits WL5020. We share these at the 12h quote stage.
Cheap UV-resistant vehicle-warmer-case: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our UV-resistant vehicle-warmer-case: $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.
Ordering UV-resistant vehicle-warmer-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.
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.
Established 2014. 13,000 sqm factory in Fusha Industrial Park, Zhongshan, 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.

UV-resistant vehicle-warmer-case: Lab Test Certificate Reference
Visual summary of the key specifications. Print-friendly for buyer reference.
📹 60-second factory + product walkthrough. UV-resistant vehicle-warmer-case lab test footage: water submersion, drop test, temperature chamber
UV exposure test per ASTM G154: 500 hours accelerated UV exposure (UVA-340 lamp, 60°C). After 500 hours, color shift ΔE < 2.0, no cracking, no chalking. Suitable for outdoor storage and direct sun exposure.
Anti-static foam option: surface resistance 10^6 to 10^11 Ω per ANSI/ESD S541. Standard foam is non-ESD. If you are transporting electronics (camera bodies, circuit boards, hard drives), specify anti-static foam.
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.
