Heavy Duty Storage Case is an engineered protective case in the protective 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 protective case is a transport and storage enclosure—typically engineered plastic or metal—for equipment, made by injection, rotational or blow molding, with impact resistance, sealing class and custom foam as the core buying criteria.
Heavy Duty Storage Case: Product & Manufacturer Overview
The Heavy Duty Storage Case is a key category in equipment protection. kexinMaterials, a source factory with injection, rotational and blow molding lines plus an in-house tool shop, serves this category from stock supply to custom tooling.
The Heavy Duty Storage Case 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.

Product Feature Breakdown
Built for heavy duty, Heavy Duty Storage Case is designed for predictable failure rather than indestructibility: kexinMaterials ensures replaceable parts — latches, handles — fail before the shell does, so a field part swap returns the case to service instead of scrapping it.
Returnable cases need batch identification: Heavy Duty Storage Case can carry an RFID tag pocket, barcode card slot and silk-screen number panel, avoiding the inventory problems caused by peeling labels. kexinMaterials supports bulk silk-screening or laser marking to a customer's coding scheme.
How kexinMaterials Compares
| Dimension | kexinMaterials | Generic market cases |
|---|---|---|
| Rating | IP67 standard, IP68 optional | Mostly IP54–IP65 |
| Material | PP/ABS/PE process selection | Single material limited |
| Foam | CNC-cut to shape | Universal dividers |
| MOQ | From 50 pcs, negotiable | Usually 500 pcs |
| Lead time | Stock 7–15 d, production 15–30 d | Unstable |
| Certification | Material/drop/immersion reports | Missing |
Large-format note: cases over 800 mm per side are best rotomolded — seamless walls, high tear resistance — and should add wheels, forklift channels and multi-person handles.
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.
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.
IP Ratings (IEC 60529)
In IP67, the “6” means dust-tight (no dust ingress after a 2 kPa vacuum dust test) and the “7” means temporary immersion: the enclosure survives 30 minutes at 1 m depth with its highest point at least 150 mm below the surface, per IEC 60529 Clause 14.2.7.
Typical Applications
- Equipment and instrument transport
- Industrial storage and turnover
- Outdoor and specialty environments
- Private label and channel distribution
Product Overview
The kexinMaterials Heavy Duty Storage 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 Heavy Duty Storage 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 Heavy Duty Storage 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 Heavy Duty Storage 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
Process is matched to the category — injection for precision sealing, rotomolding for large tough builds, blow molding for lightweight economy — with in-house tooling and batch drop/seal inspection.
Field Case Studies
4,000 enclosure cases, PP/ABS selection, tooled to device dimensions with stable mass-production lead times.
6,000 generic protective cases under OEM brand with test reports and steady reorders.
