Heat-resistant sales-kit-case from KeXinMaterials source factory. OEM/ODM, wholesale, factory-direct pricing. 9 WL series sizes WL1204-WL5020, IP67/MIL-STD-810H certified, MOQ 30, 12h quote, 35-day delivery to 47 countries.
IP67, MIL-STD-810H, ROHS, CE — the alphabet soup on Heat-resistant sales-kit-case 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 sales-kit-case 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 |
|---|---|---|---|---|---|
| WL3812-T | 380×320×120 mm | 365×280×110 mm | 1400 g | PP+Aluminum Frame | Sales Rep Kit |
| WL5020-T | 500×400×200 mm | 480×360×185 mm | 3100 g | PP+Aluminum Frame | Trade Show Case |
| WL8040-T | 800×500×400 mm | 770×470×370 mm | 8500 g | PP+Aluminum Frame | Mobile Conference Kit |
The most common model for "Heat-resistant sales-kit-case" buyers is the WL3812-T (380×320×120 mm OD, 1400 g empty weight, PP+Aluminum Frame body).
Cheap protective cases use 15 kg/m³ foam that bottoms out after 6 months. Our Heat-resistant sales-kit-case 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 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.
We maintain 200+ foam-cut reference designs for Heat-resistant sales-kit-case, 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 sales-kit-case 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.
