Engineered to meet the stringent tolerance and thermal performance requirements of France's premium manufacturing clusters.
Established in 1999, Zhejiang Laysun Magnetics Ltd. has spent over two decades pioneering the synthesis, sintering, and custom machining of high-performance rare earth NdFeB permanent magnets. As a recognized national high-tech enterprise, we service the critical engineering corridors of the globe—providing a seamless supply line to Paris, Seine-et-Marne, and the wider Île-de-France industrial hub.
Our operation is built on manufacturing density and strict technological fidelity. Across our 100,000 square meter facility, our 300-strong workforce coordinates to deliver a robust annual capacity of 5,000 tons. For Paris-based tier-1 automotive suppliers, aerospace contractors, and research-driven startups at Paris-Saclay, we offer direct factory integration, ensuring your designs transition from CAD files to field-tested hardware without structural or magnetic compromise.
Validating reliability and supply volume for major European industrial applications.
How Laysun aligns rare earth magnet manufacturing with France's technological shift and ESG mandates.
The Île-de-France region, with Paris at its center, is undergoing a profound industrial transition driven by the €54 billion "France 2030" investment plan. This national framework prioritizes the decarbonization of transport, expansion of renewable energy systems, and development of robotics. Each of these high-tech focus areas relies heavily on high-density permanent magnet assemblies. Sintered Neodymium-Iron-Boron (NdFeB) represents the gold standard for achieving the required torque-to-weight ratios in electric drivetrains, actuator assemblies, and precision positioning systems.
For Paris-based aerospace contractors, weight minimization and thermal endurance are non-negotiable parameters. Laysun’s specialized NdFeB formulations (UH, EH, and AH grades) are engineered to operate in environments experiencing extreme thermal fluctuations (ranging from -60°C to +240°C) with exceptionally low weight-loss parameters. These magnets are integrated into aircraft instrumentation, cabin environmental control systems, actuator valves, and satellite orientation systems. Each batch bound for France undergoes stringent environmental testing, validating structural integrity against high-frequency vibration and low pressure.
The Paris basin is home to major engineering offices for automotive giants and system integrators. The rapid transition to Electric Vehicles (EVs) has placed Electronic Power Steering (EPS) and traction motors under the microscope. Our custom segment magnets, utilizing advanced grain boundary diffusion (GBD) technology, minimize the consumption of heavy rare earths (Dysprosium and Terbium) while maintaining high coercivity. This delivers a cost-efficient magnet that complies with the performance demands of modern highway cruising and stop-and-go urban transit in metropolitan Paris.

| 35M - 50M | 100°C | Voice Coil Motors (VCM), Medical Electronics, Audio Transducers | Improved Thermal Coercivity (Hcj) |
| 35H - 48H | 120°C | Automotive EPS, High-Performance Pumps, Industrial Actuators | Superior Vibration & Mechanical Stability |
| 33SH - 45SH | 150°C | Traction Motors, Renewable Wind Turbines, High-Speed Rotors | Resistant to Dynamic Demagnetizing Fields |
| 30UH - 40UH | 180°C | Under-the-Hood Automotive Sensors, Servo Drive Units | Maintains Stable Magnetic Field in Elevated Temps |
| 30EH - 38EH | 200°C | Aerospace Actuators, Deep-Bore Extraction, Downhole Tools | Extreme Thermal Coercivity (Minimizes Flux Loss) |
Bridging the distance with seamless logistics and uncompromising regulatory adherence for French manufacturers.
All materials produced by Laysun are rigorously certified under REACH and RoHS regulations. We ensure our coatings (including electroplated nickel, tin, epoxy, and passivated zinc) do not contain restricted substances, allowing immediate incorporation into consumer-facing electronics across France.
Leveraging our seasoned logistical network, we offer flexible shipping modes to the Île-de-France region, including air freight for fast prototype validation and sea freight for high-volume monthly assembly runs, complete with DDP (Delivered Duty Paid) options.
Our facilities are audited to meet the automotive sector's elite benchmark: IATF 16949. By employing statistical process control (SPC) and failure mode effects analysis (FMEA), we guarantee consistency in flux density and dimension tolerances down to +/- 0.05 mm.
Our commitment to keeping French businesses competitive translates to continuous R&D investments. Our scientific pipeline focuses on two critical industry trends: Decarbonization of Sourcing and Enhanced Corrosion Resistance.
NdFeB is inherently susceptible to oxidation in humid or acidic environments—conditions common in maritime energy projects and industrial chemical facilities around northern France. To address this, we have developed advanced multi-layer coatings. Our signature Ni-Cu-Ni + Epoxy coating delivers over 72 hours of salt spray testing resistance, preventing structural breakdown in harsh environments.
Furthermore, our research team is optimizing our Grain Boundary Diffusion (GBD) process, allowing us to selectively inject heavy rare earths only where the magnet faces the highest demagnetizing strain. This results in magnets that are more cost-stable, shielding French buyers from volatility in the global rare earth market.
