Heat-resistant bullet-resistant-box from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 50, 12h quote, 30-day delivery to 47 countries.
IP67, MIL-STD-810H, ROHS, CE — the alphabet soup on Heat-resistant bullet-resistant-box marketing pages can be overwhelming. This page cuts through the noise. We publish every test result and every certificate we hold.
For your reference, here are the WL series models we typically use for Heat-resistant bullet-resistant-box 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 |
|---|---|---|---|---|---|
| WL1204 | 120×90×40 mm | 115×78×32 mm | 100 g | PP | Pistol Case |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PP+GF | Rifle Case |
| WL5020 | 500×400×200 mm | 480×360×185 mm | 2400 g | PP+GF | Multi-Rifle Kit |
The most common model for "Heat-resistant bullet-resistant-box" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Heat-resistant bullet-resistant-box uses 25 kg/m³ foam rated for 5+ year use. The difference is in the cell structure: 25 kg/m³ cells rebound after compression, 15 kg/m³ cells do not. We have tested both. The cheaper foam fails.
The shell is rated IP67 + MIL-STD-810H ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 2.0m). Temperature range is -50 ~ +90 °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.
We maintain 200+ foam-cut reference designs for Heat-resistant bullet-resistant-box, covering camera bodies, drone kits, broadcast gear, military equipment, medical devices, and industrial tools. Send us your equipment list, we will match to the closest reference or draft a new layout free within 24 hours.
When evaluating Heat-resistant bullet-resistant-box 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 Heat-resistant bullet-resistant-box 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.
Our quality management is ISO 9001:2015 certified. Our factory has been audited by SGS, TUV, and Bureau Veritas. Audit reports available on request.
Established 2014. 13,000 sqm factory in Fusha Industrial Park, Zhongshan, Guangdong. 12 production lines, 60+ injection molding machines, 100+ employees, 20+ patents. Monthly capacity 80,000 units. Annual export revenue 8M+ USD to 47 countries.
Direct from the OEM.

Visual summary of the key specifications. Print-friendly for buyer reference.
📹 60-second factory + product walkthrough. Heat-resistant bullet-resistant-box lab test footage: water submersion, drop test, temperature chamber
Resistant to: petroleum products, mineral oil, dilute acids and alkalis, alcohols, and most industrial solvents. Not resistant to: concentrated sulfuric acid, aromatic solvents (benzene, toluene), and prolonged exposure to chlorinated solvents.
Standard PP case: density 0.91 g/cm³, so yes, all our cases float. Foam-filled case with typical payload (5-30kg equipment): overall density may exceed 1.0, may not float. Specify float requirement and we adjust foam density.
Standard cases: no EMI/RFI shielding. Optional: conductive coating (nickel or copper) on interior surface for EMI shielding per MIL-STD-285. Adds $5-15 per unit depending on size. Used for sensitive electronic equipment.
ROHS 3 (EU 2015/863): compliant for all 10 restricted substances (Pb, Hg, Cd, Cr6+, PBB, PBDE, DEHP, BBP, DBP, DIBP). Third-party test report issued per batch, available as PDF on request.
5-year warranty on case body and latch (covers manufacturing defects, not normal wear). 1-year warranty on foam set (covers material degradation, not mechanical damage). Warranty does not cover misuse, modifications, or cosmetic damage.
