Raw Medical Instrument Case sourcing is what we do before the marketing layer, the catalog layer, and the lead time layer. It is the upstream conversation. Here is what it sounds like.
For your reference, here are the WL series models we typically use for Medical Instrument 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 "Medical Instrument Case" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
Medical Instrument 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.
In 2024, we shipped Medical Instrument 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.
Cheap Medical Instrument Case: $3-8/unit, 6-month lifespan, 200-cycle latch, 15 kg/m³ foam. Our Medical Instrument 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 Medical Instrument 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.
Raw spec is where we start. We do not push products — we listen first, recommend second.
