There is a difference between 'IP-rated' and 'IP-tested'. The first is a marketing claim. The second is a third-party certificate. Our Dustproof 聚丙烯改性塑料箱 is the second one.
For your reference, here are the WL series models we typically use for Dustproof 聚丙烯改性塑料箱 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 | Component Storage |
| WL2005 | 195×170×46 mm | 190×135×40 mm | 175 g | ABS | Tool Kit |
| WL3812 | 380×320×120 mm | 365×280×110 mm | 1100 g | PC+GF | Industrial Kit |
The most common model for "Dustproof 聚丙烯改性塑料箱" buyers is the WL1204 (120×90×40 mm OD, 100 g empty weight, PP body).
Four components define Dustproof 聚丙烯改性塑料箱 protection: shell (PP or PP+GF), foam (25 kg/m³ closed-cell PE), seal (silicone gasket around the lid), and pressure valve (automatic Gore-Tex membrane for IP67/IP68). Each component is tested. Each can be replaced if worn.
The shell is rated IP65 ingress protection and validated to MIL-STD-810H Method 516.8 (26 drops at 1.5m). Temperature range is -30 ~ +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.
In 2024, we shipped Dustproof 聚丙烯改性塑料箱 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.
Top 5 mistakes we see in 2024: (1) Over-specifying size — buying WL5020 when WL3812 fits. (2) Choosing by price alone. (3) Skipping IP certification. (4) Ignoring latch type. (5) Not requesting lot certificates. All five add up to a 2-3x higher TCO over 5 years.
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.

Dustproof 聚丙烯改性塑料箱: Lab Test Certificate Reference
Visual summary of the key specifications. Print-friendly for buyer reference.
📹 60-second factory + product walkthrough. Dustproof 聚丙烯改性塑料箱 lab test footage: water submersion, drop test, temperature chamber
UV exposure test per ASTM G154: 500 hours accelerated UV exposure (UVA-340 lamp, 60°C). After 500 hours, color shift ΔE < 2.0, no cracking, no chalking. Suitable for outdoor storage and direct sun exposure.
Anti-static foam option: surface resistance 10^6 to 10^11 Ω per ANSI/ESD S541. Standard foam is non-ESD. If you are transporting electronics (camera bodies, circuit boards, hard drives), specify anti-static foam.
UL94 V-2 standard (self-extinguishing within 30 seconds, no flaming drips). Higher UL94 V-0 rating available for select materials. We do not use materials with toxic flame retardants (Deca-BDE, HBCD) per ROHS.
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.
