Explore our core engineering configurations. Designed for durability, waterproof efficiency, and seamless architectural integration.
Ningbo Jianheng Import And Export Co., Ltd. (operating alongside Ningbo Yuancheng Plastic Co., Ltd.) represents the pinnacle of solar lighting fabrication in China. With a proud operating history spanning over two decades, our facility has evolved from a local component producer into an advanced, integrated manufacturing center specializing in OEM and ODM solar lighting systems.
Our manufacturing complex covers 10,750 square meters of state-of-the-art production lines. By employing 105 skilled technicians on our assembly floor and a designated engineering support group of 15 office specialists, we guarantee seamless end-to-end management of large-scale B2B distribution orders worldwide.
Meeting international criteria through systematic manufacturing checkpoints and laboratory-grade compliance testing.
Our operation is built on verified procedural management. Ningbo Yuancheng Plastic Co., Ltd. has successfully obtained BSCI (Business Social Compliance Initiative) audit certifications and functions under strict adherence to ISO9001:2015 Quality Management Systems. These protocols guarantee that our raw materials, component tracking, and manufacturing conditions align with the highest expectations of global retail chains and commercial clients.
Products are engineered to satisfy national safety and environment mandates directly upon leaving the facility. Our entire catalog holds native CE, RoHS, UKCA, and FCC compliance. We manage full custom configuration orders (OEM/ODM), offering a fast 7-day proofing and prototyping service to expedite design validations, tooling adaptations, and speed-to-market execution.
IPX5 & IPX6 Ingress Testing Station
Automated Packing & Final QA Inspection
Goniophotometric & Integrating Sphere Analysis
By positioning our manufacturing hub in the industrial heart of Ningbo, we capitalize on the world's most dense ecosystem of plastic resin suppliers, LED packaging foundries, and raw hardware fabricators. This proximity guarantees unprecedented raw material supply security, insulating our global partners from sudden micro-economic shocks or logistics constraints.
Our plant houses modern high-pressure injection molding machines, automated placement lines, and laser-guided tooling centers. By operating under one roof—from plastic housing extrusion to micro-solder reflow and ultrasonic waterproof sealing—we bypass third-party sub-contracting markups. This integration allows us to keep our pricing highly competitive while maintaining absolute traceability on every component.
Addressing key performance metrics for corporate buyers, volume importers, and municipal distributors.
Utilization of premium A-grade Monocrystalline silicon cells yielding over 22.5% photovoltaic conversion efficiency. This ensures adequate charging even in partial shade or winter months.
Long-life cycle Lithium Iron Phosphate (LiFePO4) and high-density Lithium-Ion (2200mAh to 4400mAh) battery packs fitted with customized protection PCBs against overcharge and thermal runaway.
Strict IP65 and IP67 waterproof design frameworks. Using double-gasket silicon ring inserts and UV-stabilized ABS/Stainless Steel chassis material for marine or high-salinity coastal applications.
To maintain market leadership, our engineering laboratory actively targets three primary development paths:
By refining these technical vectors, Ningbo Jianheng supports commercial clients in achieving ESG goals while supplying products that exceed typical service lifetimes.
Scalable lighting system deployment configurations for landscape architects, contractors, and real estate developers.
High-efficiency, zero-grid connection pathway lighting models (such as our 256 LED motion sensor panels and dual-head outdoor security fixtures) allow municipalities to instantly deploy safety lighting across public parks, emergency walkways, and rural transit zones without expensive trenching or wiring costs.
For leisure developments and hospitality environments, our decorative solar lines (including custom jellyfish fiber optic installations, vintage hanging flame lanterns, and stainless steel pathway spikes) deliver warm, atmospheric outdoor staging with minimal maintenance requirements.
Add custom value to modern smart-home projects with our solar illuminated house numbers and modular exterior post-cap light series. These components pair off-grid reliability with long-lasting structural value, increasing curb-appeal and properties' energy efficiency ratings.
Importing technical components requires precise compliance tracking to avoid port delays or regulatory challenges. We supply complete customs paperwork packages tailored to Europe, North America, and oceania.
Every shipment features complete documentation, including:
Our team assists with custom retail package artwork translation, instruction manual formatting, and localized barcode assignments.
Stainless steel, aluminum anodization, ABS/PC plastic colors matched to Pantone values.
CCT selections (2700k to 6500k), customized PCB circuit paths, and custom battery sizing.
Full-color gift boxes, mail-order packaging, PDQ displays, and customized master carton markings.
High-efficiency components tailored for specific decorative, domestic, and indoor-to-outdoor transition environments.
Addressing the technical, administrative, and chemical details that project managers assess during purchase reviews.
Our standard ternary Lithium-ion batteries (e.g., 2200mAh/18650 format) are rated for 500 charge-discharge cycles down to 80% capacity. For higher-performance project specifications, we supply grade-A Lithium Iron Phosphate (LiFePO4) cells which achieve up to 2000 cycles while retaining over 80% of original capacity. This ensures operation ranges of 3 to 5 years under variable climate stresses.
We deploy dual-channel silicone compression seals and automated ultrasonic weld processes to secure casing interfaces. External fasteners are structured from SS316 stainless steel to eliminate oxidation risks. In addition, our circuit boards undergo a conformal polyurethane coating step to seal exposed trace routes from moisture and airborne sea salts.
We support modifications in cell selection (poly/monocrystalline and PET, ETFE, or tempered glass encapsulation). We can also adjust output ratings (2V to 18V), dimensions to fit custom enclosures, and install integrated light sensors to eliminate external photodiode components.
Our standard prototype loop takes 7 days. For custom injection mold creation, structural tooling runs take between 25 to 30 days. Mass assembly is typically completed within 35 to 45 days after deposit clearing and packaging artwork validation, depending on season and order scale.
Every product line undergoes four standard testing gates: high-potency dark room light tests (measuring lumen output, distribution, and CCT limits), temperature chambers (-20°C to 65°C testing cycles), salt fog corrosion runs for structural pieces, and automated vibration testing to verify container shipping integrity.
