As the backbone of electromagnetic induction, Iron Cores are undergoing a revolutionary shift. From traditional power distribution to the rapid rise of Electric Vehicles (EV) and Renewable Energy Systems, the demand for "Custom Iron Core" solutions has never been more critical. High-performance iron cores—whether for solenoids, transformers, or circuit breakers—directly determine the energy efficiency, thermal stability, and response speed of the entire system.
In today's global market, procurement managers and engineers are not just looking for a "supplier," but a "technological partner" capable of providing Information Gain through material innovation, structural optimization, and precision manufacturing. At Zhejiang Jifeilong Instrument Technology Co., Ltd., we provide the engineering depth required to navigate the complexities of modern magnetic components.
The industry is moving toward Miniaturization and High Permeability. Modern iron cores must operate at higher frequencies with lower eddy current losses. The shift from silicon steel to amorphous and nanocrystalline alloys is redefining efficiency in power electronics.
Global Tier-1 suppliers now prioritize Supply Chain Resilience and Compliance. Enterprises are seeking factories that offer end-to-end integration—from raw material sourcing to CNC grinding and automated assembly—to mitigate geopolitical and logistical risks.
We provide macro-level solutions for the Smart Grid. Our iron cores for circuit breakers and solenoid valves are designed for 50-year lifespans, ensuring reliability in critical infrastructure where failure is not an option.
Our technology roadmap focuses on three pillars: Precision, Permeability, and Performance.
Selection of high-grade non-oriented silicon steel and specialty alloys to reduce hysteresis loss. We analyze B-H curves to ensure optimal magnetic saturation for each custom project.
Utilizing high-speed progressive dies to achieve micron-level tolerances. Our lamination techniques ensure minimal air gaps, maximizing the effective magnetic flux density.
Heat treatment and surface coating to prevent oxidation and improve insulation. Every iron core undergoes rigorous testing for dimensional accuracy and magnetic properties.
Established in 1999, Zhejiang Jifeilong Instrument Technology Co., LTD. (formerly Yueqing Feilong Instrument Factory) has evolved into a global leader in precision hardware and electrical components. Located at the Oujiang Port in Wenzhou City, we operate a vertically integrated facility encompassing production, processing, and high-precision grinding.
Our products are at the heart of household appliances, solenoid valves, automotive electronics, and filtration equipment.
