| 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-D | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+PC+VIP | Cold Chain 96h (2-8°C) |
The most common model for "Large checkup-case Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP+PC body).
All Large checkup-case Wholesale 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.
Common equipment we have designed Large checkup-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.
When evaluating Large checkup-case Wholesale options, focus on three metrics: (1) Foam density — cheap cases use 15 kg/m³ foam that bottoms out; ours is 25 kg/m³, 5+ year use. (2) Latch cycle rating — cheap plastic latches break after 200 cycles; ours is metal-reinforced, 5,000 cycles. (3) IP certification — every batch ships with serialized IP test certificates.
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 Large checkup-case Wholesale 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.
