As the global transition to Electric Vehicles (EVs) accelerates, the demand for robust, high-performance DC gun parts—the critical components within DC Fast Charging (DCFC) connectors and charging piles—has reached unprecedented levels. This evolution is not merely about volume; it is about the engineering excellence required to handle 800V architectures, liquid cooling systems, and megawatt-scale power transfer.
Zhejiang Jifeilong Instrument Technology Co., LTD. stands at the vanguard of this revolution, providing the precision hardware foundations that ensure global charging infrastructure is safe, efficient, and future-proof.
The roadmap for DC charging is shifting from 50kW-150kW standards to High Power Charging (HPC) exceeding 350kW. Our R&D focuses on low-resistance copper alloys and specialized plating to mitigate thermal runaway in high-current environments.
We provide holistic solutions for the entire charging ecosystem. From miniature circuit breaker components that protect the grid to high-precision shafts for industrial solenoid valves, our parts ensure system-level reliability.
Adhering to ISO9001 and strictly following UL, CE, and IEC standards, Jifeilong components are designed to withstand 10,000+ mating cycles and extreme environmental conditions, from arctic cold to desert heat.
Formerly Yueqing Feilong Instrument Factory, Zhejiang Jifeilong Instrument Technology Co., LTD. has undergone a digital transformation. Our facility in Wenzhou utilizes fully automated production lines, ensuring that every rivet, pin, and shaft meets micron-level tolerances.
For Miniature Circuit Breakers (MCB) and Molded Case Circuit Breakers (MCCB), our rivets provide the structural integrity required for high-short-circuit capacity. We use advanced metallurgical processes to ensure conductive reliability.
Charging piles require pins that can handle high mechanical stress. Our custom copper cylindrical head parts are optimized for conductivity and corrosion resistance, essential for outdoor charging stations.
We understand the nuances of the North American, European, and SE Asian markets. Our technical team provides localized support to ensure all components meet regional electrical codes.
Established in September 1999, we have evolved from a specialized factory to a global leader in electrical switch components. Located at the Oujiang Port in Wenzhou City, we leverage a strategic logistics hub to serve our international clientele. Our unchanging tenet of "Seeking truth from facts and quality first" drives every innovation.
Operate with Integrity; Multi-party Win-Win.
Be Realistic and Quality First.
Becoming the high-quality global supplier of choice for precision components.
