The most common model for "Moisture-proof instrument-case Wholesale" buyers is the WL2305 (230×180×45 mm OD, 240 g empty weight, PP body).
Shell material for Moisture-proof instrument-case Wholesale is selected per use case: standard PP for general purpose, PP+GF for heavy-duty (10% glass fiber improves impact strength by 35%). Foam is 25 kg/m³ closed-cell PE, 0.5mm CNC cut tolerance. Anti-static ESD foam (10^6-10^11 Ω) available for electronics.
The shell is rated IP67 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.2m). Temperature range is -40 ~ +80 °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 Moisture-proof instrument-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.
For Moisture-proof instrument-case Wholesale: 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 Moisture-proof instrument-case Wholesale is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (30 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
