Standards & Industry Data

Export Compliance Essentials

EU-bound cases require CE marking and REACH compliance (phthalates such as DEHP/DBP each below 0.1% in soft parts); hard cases sold via Amazon FBA need ISTA 3A transit-drop certification; shipping drones or devices with lithium batteries additionally involves UN38.3 and IATA rules. A legitimate source factory provides these test reports directly.

Shell Materials Compared (PP / ABS / PE)

Industry data puts PP (polypropylene) at ~55% of plastic protective-case share — strong chemical resistance, low-temperature toughness and cost efficiency; ABS holds ~30% with harder, glossier surfaces; large thick-wall cases favor rotomolded PE. Plastic/polymer cases together account for 63.7% of the industrial protective case market (2025).

Military Drop Test (MIL-STD-810H, Method 516.8 Proc. IV)

MIL-STD-810H (8th revision, 2019; 29 test methods) requires transit-drop samples to survive 26 drops from up to 5 ft (1.5 m) onto steel-backed concrete in varied orientations. Versus 810G, the H revision raised drop height from 4 ft to 5 ft and switched to a harder steel-backed surface.

Typical Applications

  • Field-service engineer tool kits
  • Sales sample presentation cases
  • Medical device field visits
  • Utility and telecom field equipment
  • Corporate gifts and staff kits
  • Business travel equipment carry

OEM / ODM Custom Manufacturing

kexinMaterials runs full OEM/ODM programs on the Moisture-proof Trolley Case OEM Service: drawing/sample quotation, 3D structural design, in-house tooling (35–45 days), pilot runs and mass production — under NDA throughout.

The standard private-label flow for the Moisture-proof Trolley Case OEM Service: requirement review → proposal & quote (1–3 days) → sample approval (7–15 days) → production (15–30 days) → QC & shipment. Logos via silk print, laser engraving, hot stamping or in-mold labeling.

Need speed instead of tooling? Choose tooling-free private label: adopt an existing kexinMaterials mold, switch colors and branding, and launch from just 100 pcs — the fastest route for new case brands.

Manufacturing Process

Wheel modules and handle systems integrate onto injection-molded shells with metal inserts at every load point. Wheels pass 100,000-cycle rolling tests; handles pass 50,000-cycle pull tests.

About kexinMaterials

Frequently Asked Questions

How much can a trolley case carry, and is it easy to pull?

We recommend a loaded weight below 35–45 kg. Larger wheel diameter and longer wheelbase make towing easier; for routes with steps, choose oversized all-terrain wheels or a version with auxiliary handles for two-person lifting.

What if a wheel breaks?

Wheels are modular; spare kits and a replacement guide are provided — a ten-minute DIY job. Volume orders ship with spares.

Can you supply nested sets in three sizes?

Yes. We offer same-series size sets whose shells stack and lock together with clips so one person tows several at once. Matching colors and nameplates give teams consistent equipment management and presentation.

Are you a factory or a trading company?

kexinMaterials is a source factory for engineered plastic cases based in Guangdong, China, with injection, rotational and blow molding lines and an in-house tool shop. Factory audits and video tours are welcome.

How are display inserts customized?

Send your sample list and dimensions (or samples). We design the cutout layout and display angles, confirm a 3D render, then produce.

Is it cabin-approved?

Models under 20 inches meet most airline cabin limits; for check-in choose an IP67 sealed model with a TSA lock.

Key Terms Explained

OEM / ODM
OEM means manufacturing to the customer's design under the customer's brand; ODM means the factory designs the product and the customer rebrands it. In case sourcing, private-labeling an existing shell is OEM, while commissioning a new shell and interior design is closer to ODM.
Pressure equalization valve
A one-way breather fitted to the case wall that lets air pass slowly while blocking water and dust. It balances internal and external pressure during air freight or altitude change, preventing a vacuum-locked lid or a deformed gasket.
Load rating
The maximum payload a case can carry while keeping shell and handle structurally safe. Injection-molded carry cases are typically rated 25–40 kg and large rotomolded transit cases 80–150 kg; overloading deforms the floor and breaks handles.
