Deep Dive
Our export director Wang Tao reports that High-strength leak-proof-3-layer-case is not a simple plastic box—it involves 4 dimensions: material engineering, mold design, IP rating matching, and application validation.
Our in-house 2024-2026 test data shows that High-strength leak-proof-3-layer-case from our factory has a return rate of just 0.3%, far below the industry average of 3-5%. We credit this to source materials + strict QC.
In my honest opinion when choosing High-strength leak-proof-3-layer-case, follow my 3-step rule: check factory size (13,000㎡ is the baseline), check certifications (CE/ROHS/IP67 is the minimum), and check patent count (20+ means reliable).

FAQs
What is your MOQ?
Standard SKUs have an MOQ of 50-100pcs; custom mold MOQ is 300pcs. Small batch trial orders of 50pcs are negotiable if we share existing molds.
Do you provide samples?
Standard SKU samples are free (shipping paid by client, 5-7 working days via DHL/FedEx). Custom samples require mold fees, refundable or deductible from bulk order.
What does IP67 mean? How deep can it go?
IP67 is the international protection rating: 6 = dust-tight, 7 = immersion in 1m water for 30 minutes without ingress. Our IP67 cases pass IEC 60529. For deeper underwater use, IP68 (5-30m) is available.
How to choose explosion-proof rating?
Common ratings: Ex ib IIB T4 (IIB gas, T4 temp ≤135°C), Ex d IIB T4 (flameproof), Ex e IIB (increased safety). Li-battery transport typically uses Ex ib IIB T4. Contact kexin@beeaa.com for certified solutions.
How long do vaccine cold-chain cases maintain temperature?
2-8°C cold chain: 48-72h passive (PCM phase change). -20°C freezer: -25°C±2°C for 96h. -70°C dry ice: VIP vacuum insulation, -70°C±2°C for 72h. GPS temperature logger optional.
