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
Market Size & Growth
The global industrial protective case market was worth about USD 2.05 billion in 2025 and is projected to reach USD 2.88 billion by 2032 (5.0% CAGR). Military & defense is the largest application (~30%), drone-related cases are the fastest-growing niche, North America is the largest region and APAC grows fastest.
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.
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
OEM / ODM Custom Manufacturing
kexinMaterials runs full OEM/ODM programs on the Waterproof Suitcase 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 Waterproof Suitcase 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.
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.
