FAQs
Is KeXinMaterials a factory or a trading company?
KeXinMaterials (Guangdong) Co., Ltd. is a source factory with an 18,000㎡ facility. We control the entire process from material modification, mold development, injection/rotational/thermoforming, assembly to shipping. Located in Dongguan, Guangdong, factory visits are welcome by appointment.
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.
