Instrument Case Factory 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 1.2m). 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.
Here are 3 real Instrument Case Factory 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.
For Instrument Case Factory, the decision comes down to: equipment dimensions (always measure with 5-10mm foam clearance), IP rating (IP65 indoor, IP67 outdoor, IP68 water), and certification (FCC for USA, CE for EU, MIL-STD for military). Beyond that, it is foam layout and quantity discount.
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 Instrument Case Factory 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.
