Heavy-Duty Rotomolded Cases
Ruggedized protective & rescue case systems engineered and manufactured by JinHouDun (JHD) - China leading defense-equipment manufacturer with 24 years in military packaging. Annual capacity 1,000,000 units, up to 8 meters.
Funder rotomolded cases follow a serialized, combinable, modular design across five product families addressing storage/transport, airdrop, command, rescue, medical and special operations. All families share one military-grade platform: rotomolded one-piece construction, IP67 sealing, impact cushioning, wide-temperature durability, flame-retardant/anti-static materials, modular containerization and deep customization.
Six Core Advantages
Rotomolded One-Piece Construction
The case body is formed in a single piece with no weld seams, naturally creating a frame-like support structure; corners are thickened for higher strength and impact resistance.
IP67 Sealing + Flotation
High-quality gaskets with a special lid structure (line-surface + enclosed ring seal) achieve IP67 - watertight when submerged; can serve as a flotation/survival aid.
Impact Cushioning + Airdrop
High-impact composite with damping liner absorbs energy; passes ammunition-case drop tests. Enables parachute-free airdrop of tens of kg from 150-300 m, all terrains, reusable.
Flame Retardant V-0 + Anti-Static
Material reaches V-0 flammability (GB/T2408-2008) - self-extinguishing under intense heat; anti-static additive provides EMI shielding.
Wide Temperature & Weatherability
Storage -55C to 70C; Operating -41C to 46C; resistant to salt fog, fungus and humid heat, meeting GJB150A.
Modular + Deep Customization
Same-module cases stack, fork-lift and crane-load; liners cut to equipment. Latches, handles, pressure valves, wheels, color and silk-screen all customizable.
Five Product Families
General Storage, Transport & Maintenance
Standardized, modular, container-ready cases and maintenance sets with pallets and straps; optional wheels and fork-slots.
Airdrop-Protective
Ultra-light high-impact composite; parachute-free airdrop 150 m+, 80+ kg payload, reusable, all terrains.
Command & Communication
Integrated rotomolded body, IP67; built-in comms gear deploys fast in harsh environments; integrable mobile power.
Rescue & Emergency
Turnkey rescue/support kits and firefighting modules; cut-to-fit damping; 49-case / 56-case turnkey units.
Medical, UAV & Special-Purpose
Blood-transport, field fridges, nucleic-acid test cases (T800 carbon fiber + aramid); UAV cases with custom liners.
