In the ecosystem of Low-voltage electrical systems, cores and shafts represent the mechanical heart. A shaft in a Miniature Circuit Breaker (MCB) or Molded Case Circuit Breaker (MCCB) must withstand thousands of operational cycles without deformation. Our components are engineered to provide the precise kinematics required for rapid contact separation during overcurrent events, ensuring electrical safety and arc extinction.
We utilize high-grade materials such as cold-rolled steel, stainless steel, and specialized copper alloys for our rivets and pins. Each part undergoes rigorous heat treatment and surface plating (Zinc, Nickel, or Tin) to resist corrosion and oxidation in harsh industrial environments. Our focus on Information Gain means we provide data on tensile strength and hardness levels that exceed IEC 60947-2 standards.
With over two decades of expertise since 1999, Zhejiang Jifeilong Instrument Technology Co., Ltd. integrates Expertise, Experience, Authoritativeness, and Trustworthiness. Our ISO 9001:2015 certification is not just a badge; it's a commitment to a zero-defect manufacturing philosophy applied to every solenoid valve core and hardware component we ship.
Established in September 1999, Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) has grown into a titan of electrical switch components. Located at the Oujiang Port in Wenzhou, we leverage a complete production ecosystem—from automated grinding to high-precision processing.
Our products serve critical sectors: home appliances, solenoid valves, automotive electronics, and high-tech filtration equipment. By implementing strict quality control from raw material to delivery, we ensure every shaft and plastic product meets the exacting demands of over 100 enterprise customers across China and the globe.
Be realistic and quality first in every rivet produced.
Global high-quality component supplier.
The rise of New Energy Vehicles (NEV) demands high-adaptability copper cylindrical head parts. Our roadmap includes the development of ultra-low resistance connectors to support DC fast charging, minimizing heat generation and maximizing energy efficiency.
Future circuit breakers will be "Smart." We are optimizing our MCB rivets and levers for miniaturized electronic sensors that monitor real-time load, ensuring our mechanical parts can keep up with millisecond-speed digital switching.
We are transitioning to green manufacturing by reducing material waste through precision stamping and adopting recyclable aluminum alloys for molded case circuit breaker rivets, aligning with global ESG standards.
The "China Factory" advantage is no longer just about cost—it is about efficiency and resilience. At Jifeilong, we have achieved fully automated production capacity. This automation allows us to offer 3-5 day shipping on standard orders, a feat impossible without a highly integrated local supply chain.
Being based in Wenzhou, the "Electrical Capital of China," we have immediate access to raw material testing labs, specialized plating facilities, and logistical hubs. This proximity reduces carbon footprints and mitigates global supply chain disruptions. Our OEM/ODM services provide free samples, allowing international partners to verify our precision nozzle and valve cores before bulk commitment.
