As the European Union drives carbon neutrality through the European Green Deal and France accelerates its own "France 2030" investment plan, the demand for high-performance rare-earth magnetic solutions has risen significantly. French manufacturing hubs—ranging from high-end aerospace labs in Toulouse to electric vehicle (EV) Gigafactories in the northern "Battery Valley" (Dunkirk, Douai)—depend heavily on advanced Neodymium-Iron-Boron (NdFeB) magnetic systems to improve energy efficiency and mechanical reliability.
Zhejiang Laysun Magnetics Ltd. provides the critical bridge between raw-material engineering and precision French application requirements. By engineering custom magnetic circuits, including Halbach arrays and optimized steel-encased pot magnets, we maximize magnetic flux density while reducing raw rare-earth usage. This helps French industrial partners lower production costs and reduce the carbon footprints of their end products.
Under the EU Critical Raw Materials Act, maintaining secure supply chains for Neodymium (Nd), Praseodymium (Pr), Dysprosium (Dy), and Terbium (Tb) is a high priority. With our 100,000-square-meter manufacturing facility and an annual capacity of 5,000 tons of rare earth magnets, Zhejiang Laysun Magnetics Ltd. offers French and European OEMs a stable and reliable supply of high-grade magnetic materials.
Delivering high-tech manufacturing, engineering expertise, and quality control systems certified to international standards since 1999.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has evolved from a local manufacturer into a global supplier of rare earth NdFeB permanent magnets and complex magnetic assemblies. Our manufacturing operations utilize advanced vacuum induction melting (VIM), strip casting, and hydrogen decrepitation (HD) technologies. This allows us to supply high-stability magnet grades designed to meet the demands of modern electric motors, automotive steering systems (EPS), and industrial automation.
Tailoring magnetic solutions to meet the technical standards of France's leading manufacturing and infrastructure projects.
We manufacture customized sintered NdFeB arc segments with high thermal stability (grades H, SH, UH, EH, AH) for EV traction motors, auxiliary electric drives, and Electronic Power Steering (EPS) systems supporting the French automotive supply chain.
Our NdFeB pot magnets, custom yokes, and sensor-actuator assemblies are engineered to perform reliably under high vibration and thermal variations, supporting defense applications and commercial aerospace engineering.
Providing high-precision cylinder, block, and ring magnets with tight dimensional tolerances (down to ±0.05mm). These components are integrated into servo motors, robotic joints, and linear actuators used in smart factories across France.
Understanding physical properties is critical to choosing the correct magnetic assembly for industrial environments.
Sintered Neodymium-Iron-Boron magnets are susceptible to thermal demagnetization if exposed to temperatures exceeding their maximum operating threshold. Adding heavy rare earths like Dysprosium (Dy) and Terbium (Tb) preserves coercivity (Hcj) at elevated temperatures. Our manufacturing process uses Grain Boundary Diffusion (GBD) technology, which reduces overall Dy/Tb content while maintaining high thermal stability.
Refer to the table below for standard parameters of our common magnet grades:
Neodymium is prone to oxidation in humid or corrosive conditions. We offer several surface protection coatings for applications in coastal industrial zones like Normandy or Marseille:

Answers to common technical, logistics, and compliance questions about sourcing magnetic assemblies for France.
For custom engineering projects, the prototype phase typically takes 2–3 weeks, depending on design complexity and testing requirements. Mass production is completed within 3–4 weeks. Standard sea freight to ports like Marseille or Le Havre takes approximately 30–35 days, while air freight is available for urgent requirements, delivering within 5–7 days.
Every shipment is accompanied by Material Safety Data Sheets (MSDS) and RoHS/REACH compliance certificates. Our raw material batches undergo regular testing by certified laboratory services (SGS) to verify that heavy metal content and restricted chemicals remain well within EU regulatory limits.
For under-the-hood automotive applications where ambient temperatures can reach 120°C to 180°C, we recommend using NdFeB SH, UH, or EH series magnets. These grades maintain magnetic output and resist demagnetization under typical operating conditions. Our team can help model thermal performance during the design phase.
Yes. We specialize in engineering and assembling complex magnetic circuits. Using multi-pole magnetization and precision steel or aluminum housings, we build assemblies that concentrate magnetic flux in specific directions, helping optimize performance for sensors, linear motors, and medical devices.
