polar-insulation-case MOQ from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 100, 12h quote, 25-day delivery to 47 countries.
Choosing polar-insulation-case MOQ for the first time is harder than it looks. We have seen buyers overspend 2x by over-specifying size, and underspend by skipping certifications. This page is the decision framework.
If you have not worked with the WL series before, this is the cheat sheet. WL1204-WL1504 are Small (under 200mm). WL1905-WL2808 are Medium (200-300mm). WL3812-WL5020 are Large (300-500mm). Within each tier, the model number encodes the length, width, height in cm.
| Model | Outer (mm) | Inner (mm) | Weight (g) | Material | Size Class |
|---|---|---|---|---|---|
| WL1204 | 120×90×40 mm | 115×78×32 mm | 100 g | PP | Phone / Wallet |
| WL2005 | 195×170×46 mm | 190×135×40 mm | 175 g | PP | Action Camera / GoPro |
| WL2808 | 275×230×82 mm | 265×190×76 mm | 480 g | PP | Tablet / E-reader |
The most common model for "polar-insulation-case MOQ" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
polar-insulation-case MOQ 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 IP68 (submersible 5m / 30 min) ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -30 ~ +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.
In 2024, we shipped polar-insulation-case MOQ 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.
When evaluating polar-insulation-case MOQ 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 polar-insulation-case MOQ is 5 steps: inquiry (12h response), quote (with recommendation), PO + 30% deposit, production (25 days + QC photos), balance payment + shipment. Repeat orders are 15-20 days. Custom OEM/ODM adds 25-30 days for mold.
We have 150+ custom design cases since 2014. Whatever your question is, we have probably seen it before.

Yes, custom colors available for orders >500 units. Color match to Pantone / RAL: $300 color matching fee, 7-10 days. Standard colors (black, gray, olive, orange) ship with no extra cost and 25-30 day lead time.
We use injection molding exclusively — denser walls, tighter tolerances, better IP rating. Blow molding produces hollow cases with thinner walls (1-2mm), cheaper, but not suitable for IP67 or MIL-STD-810H drop test. If a supplier offers 'injection' at 1/3 our price, it is likely blow-molded.
Yes for DDP and CIF. For FOB or EXW, we ship to a commercial port or address with customs broker. Residential delivery in some regions (EU, USA) requires a local broker to handle customs clearance.
