In the era of Industry 4.0, Metal Sample Prototyping has transitioned from a simple design validation step to a critical strategic asset. As global supply chains diversify, the demand for high-fidelity metal prototypes in sectors like Electric Vehicles (EV), Aerospace, and Smart Energy Management is surging. China remains the epicenter of this manufacturing revolution, offering an unparalleled blend of material availability, skilled labor, and rapid scalability.
Current trends indicate a shift towards "Miniaturization" and "High-Complexity Assemblies." Manufacturers are no longer looking for standalone parts; they seek integrated solutions where rivets, shafts, and nozzle components are engineered to work in harmony. The integration of AI-driven design optimization and automated quality control ensures that samples produced today are identical to the millions produced tomorrow.
Our technological trajectory focuses on zero-defect manufacturing. By leveraging advanced CNC machining, precision cold heading, and multi-stage automated grinding, we achieve tolerances within microns. Future horizons include the integration of IoT sensors within manufacturing molds to provide real-time data on material stress and thermal expansion during the prototyping phase.
Years of Expertise
Enterprise Clients
Certified Quality
Established in September 1999 (formerly Yueqing Feilong Instrument Factory), Zhejiang Jifeilong Instrument Technology Co., LTD. has evolved into a powerhouse of precision manufacturing. Located at the Oujiang Port in Wenzhou City, we command a full-spectrum production ecosystem including machining, grinding, and automated assembly departments.
Our core competency lies in the integrated manufacturing of electrical switches, shafts, hardware components, and plastic products. By strictly implementing ISO9001 standards, we ensure that every component—from a miniature rivet to a high-capacity EV charging pile part—meets the rigorous demands of the global market. Our transition to fully automated production represents our commitment to "Management Innovation" and "Technological Superiority."



As the world pivots toward sustainable transport, our custom copper cylindrical head parts and high-adaptability pins are vital for EV charging piles. These components are designed to withstand high thermal loads and frequent mechanical cycling, ensuring safety and longevity in public and private charging networks.
Miniature Circuit Breakers (MCB) and Molded Case Circuit Breakers (MCCB) require absolute structural integrity. Our rivets and shafts provide the robust mechanical foundation necessary for the reliable tripping mechanisms that protect homes and industries globally from electrical faults.
Precision nozzle components and valve cores are essential for high-frequency solenoid valves used in industrial automation and smart water management. Our manufacturing processes ensure corrosion resistance and tight sealing capabilities across diverse temperature ranges.
The next decade of Metal Sample Prototyping will be defined by "Smart Materials" and "Generative Design." At Jifeilong, we are already experimenting with alloy compositions that offer better conductivity while reducing weight. Our "People-Oriented" philosophy drives us to invest in R&D that simplifies the assembly process for our clients, reducing their overall production time and costs.
