Secure Document Case Custom Design Service: send your equipment dimensions or 3D files and kexinMaterials returns a free case-selection and foam-layout proposal, prototypes from its in-house tool shop, and supports logo, color and packaging customization.
A military-grade protective case is a MIL-SPEC transit container built from modified engineering plastics with one-piece molded construction, IP67 sealing, a -40°C to +80°C service range and impact-resistant structure, verifiable against MIL-STD test profiles.
Secure Document Case Custom Design Service: Product & Manufacturer Overview
kexinMaterials supplies the Secure Document Case Custom Design Service to defense contractors, law-enforcement suppliers and emergency-response distributors worldwide. Cases can be verified against MIL-STD test profiles including salt fog, vibration and temperature cycling on request.
When sourcing a Secure Document Case Custom Design Service, professional buyers evaluate three things: impact structure, sealing class and custom foam capability. kexinMaterials answers all three with reinforced one-piece shells, IP67 sealing with automatic pressure equalization valves, and CNC-cut EVA inserts machined to your equipment's exact geometry.

How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|
| Protection rating | IP67 (IP68 available, with third-party immersion report) | Mostly IP54–IP65, rarely independently tested |
| Shell material | Modified PP / ABS / rotomolded PE, chosen by load | Generic PP or recycled material, inconsistent |
| Impact structure | One-piece ribbed shell, verified to MIL-STD-810H 516.8 | Thin-wall molding, no drop verification |
| Custom foam | CNC-cut EVA/foam to your equipment 3D data | Universal dividers only, no precision pockets |
| MOQ | From 50 pcs on existing molds, negotiable for tooling | Usually 500–1,000 pcs |
| Certification & delivery | Material/drop/immersion reports, factory audits welcome | Reports missing, lead time unstable |
Standards & Industry Data
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).
Extreme Temperature Performance
Engineering-grade cases typically operate from -30°C to +80°C (military testing follows MIL-STD-810H Methods 501.7/502.7 for temperature and 503.7 for thermal shock, cycling as wide as -40°C↔+71°C). For cold climates choose PP copolymer or PE shells — standard ABS embrittles at low temperatures.
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
- Defense equipment transport and field deployment
- Law-enforcement gear storage and patrol carry
- Regulated transport of blasting materials
- Emergency-response pre-positioned supplies
- Field testing for defense research institutes
- Security equipment inspection rounds
OEM / ODM Custom Manufacturing
kexinMaterials runs full OEM/ODM programs on the Secure Document Case Custom Design 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 Secure Document Case Custom Design 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
Small and mid-size carry cases are produced by high-pressure injection molding for dimensional precision, while large transit and airdrop cases are rotationally molded for seamless walls and maximum toughness. Every production batch passes drop and seal spot checks before shipment.
Field Case Studies
Customized 1,200 camo tactical cases for carry and patrol gear, CNC-cut to sidearm and body-cam shapes with seal holes and shoulder straps; fielded in 2024 with zero damage reports.
OEM-branded 5,000 OD-green tactical cases with CE/REACH docs, delivered in three batches, >40% repeat rate.
