Precision Engineering Meets Global Manufacturing Excellence
Founded in the heart of China’s manufacturing growth triangle in Yuyao, Zhejiang Province, Ningbo Jinlong Electric Appliance Co., Ltd. is a premier high-tech enterprise specializing in two core industrial pillars: Professional Mold Manufacturing and Advanced Home Appliance R&D.
Spanning a massive 68,000-square-meter modernized facility with $16 million USD in fixed assets, we are strategically positioned near the Ningbo Port and International Airport, ensuring seamless global logistics and supply chain efficiency to our clients in the United States and global markets.
The United States electrical market is undergoing a massive transformation driven by the Bipartisan Infrastructure Law and the rapid expansion of renewable energy systems. From regional power grid upgrades to the installation of millions of Electric Vehicle (EV) charging stations, the demand for durable, non-metallic protective solutions has reached unprecedented levels. PVC moulding and conduit components serve as the primary protective envelope for critical wiring. Their natural resistance to corrosion, moisture, and chemical exposure makes them indispensable in states prone to harsh weather conditions, such as coastal Florida, Texas, and California.
Entering and succeeding in the United States market requires strict adherence to localized electrical codes. PVC moulding products must meet the standards set by Underwriters Laboratories (UL), specifically UL 651 for rigid non-metallic conduits and fittings, and UL 94 for flammability ratings. Furthermore, NEMA (National Electrical Manufacturers Association) guidelines govern the structural integrity of enclosures. As an export-oriented manufacturer, our products are engineered to comply with NEC (National Electrical Code) Article 352, ensuring that US contractors can confidently install our components in commercial, residential, and industrial environments without compliance bottlenecks.
The PVC electrical moulding industry is moving away from traditional, heavy-metal stabilized compounds toward eco-friendly, lead-free, and low-smoke halogen-free (LSHF) formulations. In high-density public spaces like subway systems, airports, and smart corporate offices, LSHF PVC moulding prevents toxic smoke emission during thermal events. Additionally, advanced injection moulding processes allow for co-extrusion and multi-cavity precision tooling, reducing production cycle times while boosting mechanical strength. This technical evolution ensures that electrical fittings are lighter yet significantly more impact-resistant.
Leveraging decades of industrial experience to deliver high-precision tooling and cutting-edge consumer technologies.
