What does Heat-resistant doctor-diagnostic-bag actually deliver? 1.2m concrete drop, 30 minutes at 1m underwater, -40 to +80°C, 5,000 latch cycles. We can show you the test videos and the SGS certificates.
For your reference, here are the WL series models we typically use for Heat-resistant doctor-diagnostic-bag 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 |
| WL6030-O | 600×450×300 mm | 575×420×280 mm | 4200 g | PP+PC+VIP | Organ Transport |
The most common model for "Heat-resistant doctor-diagnostic-bag" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
All Heat-resistant doctor-diagnostic-bag 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 -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.
In 2024, we shipped Heat-resistant doctor-diagnostic-bag 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.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
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 Heat-resistant doctor-diagnostic-bag 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.
