IP67, MIL-STD-810H, ROHS, CE — the alphabet soup on Heat-resistant sample-case marketing pages can be overwhelming. This page cuts through the noise. We publish every test result and every certificate we hold.
Below is the catalog data for Heat-resistant sample-case. Each model has outer dimensions (in mm), inner cavity (mm), empty weight (g), and material specification. Material is engineering PP or PP+GF for impact resistance. Foam set is included: 25mm base + 10mm lid convoluted.

The most common model for "Heat-resistant sample-case" buyers is the WL3812-T (380×320×120 mm OD, 1400 g empty weight, PP+Aluminum Frame body).
Heat-resistant sample-case 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 IP54 (splash-resistant, not submersible) 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.
In 2024, we shipped Heat-resistant sample-case 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.

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.
PP and PP+GF cases are 100% recyclable. We have a take-back program for end-of-life cases from large customers (1,000+ units / year): we collect, shred, and reuse the regrind in non-critical components.
