Waterproof Transport Case is an engineered protective case in the trolley case family: built by source factory kexinMaterials with IP67 sealing, impact-resistant PP copolymer or rotomolded PE shells and CNC-cut custom foam; wholesale, OEM and export supported.
A trolley case combines a hard protective shell with a telescopic handle and wheels for suitcase-style mobility, ideal for accompanied baggage, trade shows and frequent travel.
Waterproof Transport Case: Product & Manufacturer Overview
The kexinMaterials Waterproof Transport Case shares modified-PP compounds and sealing architecture with our protective line, adds silent spinner wheels and multi-stage aluminum handles — a presentable, dependable answer for engineers' tool kits, sales demos and field equipment.
For corporate gifting and procurement, kexinMaterials runs small-batch personalization: corporate-color molding, logo printing or laser engraving and tailored interiors, from 500 pieces.
Key Specifications
| Shell material | Modified PP / ABS+PC |
|---|---|
| Wheels & handle | Silent spinners / multi-stage aluminum |
| Locks | Latch / combination / TSA optional |
| Interior | Display cutouts / tool layers / dividers |
| Use cases | Tool kits, sample demos, field equipment, business travel |
| Customization | Corporate color, logo, interiors, from 500 pcs |
| Ingress rating | IP67 (1 m / 30 min immersion, 100% tested) |
Product Feature Breakdown
A practical way to judge whether Waterproof Transport Case is genuinely sealed is the automatic purge valve: without one, cabin depressurisation or heat lifts the gasket off its seat, and water enters after landing. kexinMaterials fits a Gore-equivalent breather valve that equalises pressure while blocking liquid water.
How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|
| Wheels | Heavy-duty casters + aluminium trolley, loaded drag | Cheap wheels fail |
| Shell | ABS/PP composite, stack-resistant | Single resin deforms |
| Liner | Zoned fixation foam for gear | No zoning |
| Rating | IP67 optional | Usually non-protected |
| MOQ | From 50 pcs, size custom | Few stock sizes |
| Use | Film/expo/inspection mobility proven | Lacks proof |
Waterproofing: rated IP67 — fully dust-tight and leak-free after 30 minutes at 1 m depth. Sealing relies on a continuous silicone gasket in a molded rim channel, plus an automatic pressure valve so the case opens normally after rapid pressure changes.
Standards & Industry Data
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.
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).
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.
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
Product Overview
The kexinMaterials Waterproof Transport Case is one-piece molded from engineering plastics, balancing impact strength, sealing and long-term durability — available from stock or fully customized. Key specs below.
On process: the Waterproof Transport Case can be injection, rotational or blow molded. Injection gives precise sealing and repeatability; rotomolding yields large seamless shells with thick-wall toughness; blow molding suits light, economical builds. kexinMaterials runs all three lines and matches the process to your protection grade and budget.
For interior protection, the Waterproof Transport Case ships with or accepts CNC-cut EVA/PE foam, routed to your equipment's 3D data so nothing shifts in transit; precision instruments can add ESD-safe or cushioned layered structures.
On quality, the Waterproof Transport Case passes batch drop, stack and immersion checks; key models can be tested to MIL-STD-810H for drop and vibration, with material and third-party test reports supplied for export and industry acceptance.
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.
Field Case Studies
1,600 mobile gear cases with heavy-duty casters and trolley, easier location moves.
1,200 exhibit-transit cases with zoned foam, faster booth setup.
