Deep Suitcase: confirm internal dimensions first (equipment size plus foam allowance), then protection rating (IP67 is the benchmark) and shell material (PP for value, ABS for surface hardness, rotomolded PE for large sizes). Custom sizes available via tooling.
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.
Deep Suitcase: Product & Manufacturer Overview
For corporate gifting and procurement, kexinMaterials runs small-batch personalization: corporate-color molding, logo printing or laser engraving and tailored interiors, from 500 pieces.
The Deep Suitcase can be tailored to your brand and project: case color, silk-print or laser-engraved logo, foam layout and handle/wheel options are all adjustable. kexinMaterials, as the source factory, runs the whole journey from sample approval to mass production, including neutral shipping and OEM private label.

Standards & Industry Data
Foam Inserts (EVA / PU / XLPE)
Three insert materials dominate: EVA (closed-cell, waterproof, firm support for precision instruments), PU foam (open-cell, soft cushioning, economical) and XLPE (chemically inert, non-shedding — preferred for medical and optics). CNC pockets are cut from the equipment's 3D data; drawing-to-first-sample typically takes 1–2 weeks.
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).
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
Sizing & Selection Guide
To size a Deep Suitcase, measure the largest 3D dimensions of the payload and allow 30–50 mm per side for foam, then match against internal case dimensions. Above 30 kg payloads, add wheels and reinforced bases.
kexinMaterials stocks a full size run from personal cases to large transit trunks with published internal dimensions; if nothing fits, we evaluate mold revisions or new tooling — selection advice is free.
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.
