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 offer OEM/ODM services?
Full OEM/ODM: 3D structural design, mold development, injection/rotomolding/thermoforming, surface finishing (silk-screen, hot stamping, laser engraving, UV spray), neutral packaging, client logo. No strict mold MOQ (small orders can share molds).
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.
Are trolley cases carry-on size?
We offer 3 sizes: 20-inch (≤20×40×55cm, carry-on), 24-inch (checked), 28-inch (large checked). 20-inch + IP54 + silent PU wheels is ideal for business travel.

Deep Dive
When we visited our largest US distributor in 2024, they told us Marine300LTrolley Case is not a simple plastic box—it involves 4 dimensions: material engineering, mold design, IP rating matching, and application validation.
Based on 200+ batch tests we have run, Marine300LTrolley 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.
I would recommend when choosing Marine300LTrolley 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).

Deep Dive
Wei Li's take: "Factory-direct means 30-50% savings, but more importantly, it means you can audit the production line yourself. ". In Q1 2026, a German outdoor brand tested 4 factories for Marine300LTrolley Case. We were the only one who passed their 5-meter drop test on the first try. Order value: $120K.
