As modern technology scales down in footprint and ramps up in power density, thermal management has graduated from a secondary design factor to a critical bottleneck in global electrification. In high-power applications, such as Miniature Circuit Breakers (MCBs), Solenoid Water Valves, and New Energy Vehicle (NEV) charging points, thermal management components play an indispensable role. Heat generation, if not mitigated, directly degrades material efficiency, damages mechanical structures, and increases electrical impedance, presenting significant risks to grid infrastructure and hardware lifespans.
For global OEMs, selecting a component manufacturer involves analyzing precision metallurgical execution, structural design capabilities, and dynamic thermal dissipation engineering. Traditional passive cooling methods are shifting toward micro-channel liquid routing and advanced high-conductivity alloys. In water control systems, precision-ground nozzles regulate thermal fluid dynamics to secure reliable system integrity under extreme environments.
Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) has navigated these industry challenges by upgrading its facilities into a smart, fully automated Factory 4.0 infrastructure. Nestled inside the Oujiang Port logistics cluster of Wenzhou City, the company integrates advanced raw material selection with precision CNC machining, grinding, and multi-stage surface treatments. This localized industrial concentration minimizes structural lead times, yielding an agile supply chain capable of delivering customized hardware components worldwide.
Strategically located near major global ports, Zhejiang Jifeilong handles overseas demand efficiently. The transition to fully automated manufacturing has helped lower production margins and establish strict quality baselines. Standard orders are typically processed and shipped within 3 to 5 days, maintaining high operational agility.
By enforcing precise automated processes, Zhejiang Jifeilong ensures that every rivet, pin, and copper cylindrical head conforms to strict dimensional standards, ensuring trouble-free drop-in installation on clients' assembly lines.

Established in September 1999, Zhejiang Jifeilong (formerly Yueqing Feilong Instrument Factory) has grown into a highly integrated components manufacturer. With state-of-the-art production, processing, and grinding divisions, our product portfolio spans across various electric switches, shafts, molded plastic parts, and high-conductivity hardware components.
Our solutions serve home appliances, solenoid valve networks, consumer electronics, automotive assemblies, and high-performance water filtration systems. Certified under ISO9001 quality frameworks, our operations ensure strict inspection control across all stages, from raw material procurement to final shipping.
We are mainly engaged in the integrated manufacturing and sales of various electrical switches, shafts, plastic products, and hardware components across these product divisions:
Designed for high electrical safety and reliable operation in MCCBs.
Combining lightweight properties with secure structural fastening.
Crucial to the safety, stability, and durability of the entire electrical switch system.
Engineered for high fatigue limits under high vibration environments.
Precision-headed copper and iron rivets for secure electrical contacts.
Securing internal mechanism linkages with strict tolerance control.
Our custom thermal management and electrical components are integrated into specialized systems across major industrial zones worldwide. We align our manufacturing processes with the distinct engineering standards and geographic demands of our global partners:
High-current charging environments demand thermal terminals that handle rapid heat dissipation. Our OEM copper cylindrical head components provide stable conductivity to help prevent overheating at critical power interfaces.
In high-precision manufacturing, liquid cooling lines require consistent pressure regulation. Our custom nozzle components help prevent fluid erosion and support system stability in heavy machinery solenoid valves.
In modern smart grids, miniature circuit breakers need to operate reliably through frequent power cycles. Our precision rivets and shafts maintain their structural integrity to prevent early joint failures under electrical loads.
