Explore our flagship precision-engineered magnetic products for advanced industrial applications in Luxembourg and worldwide.
Luxembourg, renowned as a premier financial and logistical gateway of the European Union, is driving a profound transition toward high-tech manufacturing, e-mobility, and automation. Located in the heart of Europe, the Grand Duchy hosts a sophisticated automobility and industrial innovation ecosystem. Enterprises operating in sectors such as sensor technologies, precision instrumentation, and robotics require highly reliable magnetic materials that meet rigorous specifications.
Bonded Neodymium-Iron-Boron (NdFeB) magnets have emerged as a critical component in modern electrical engineering. Unlike their sintered counterparts, bonded NdFeB magnets offer unparalleled freedom of design. Through advanced injection molding or compression methods, complex geometries can be produced with precise dimensional control, eliminating the need for costly secondary machining processes.
Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has evolved into an industry-leading, national high-tech enterprise. We specialize in the R&D, fabrication, surface treatment, and global supply of high-grade rare earth magnets, with a primary focus on both bonded and sintered NdFeB systems.
Our main manufacturing facility covers a massive 100,000 square meters in Suining, Sichuan. This geographic selection allows us to benefit from optimized energy structures and secure local supply chains for rare earth elements. With over 300 highly qualified technicians and production specialists, we run automated processing lines capable of delivering an annual output exceeding 5,000 tons of premium magnetic products.
To serve the European market, particularly precision manufacturing hubs like Luxembourg, we align our operations with rigorous Western engineering standards, ensuring high repeatability, stable coercivity, and immaculate structural integrity.
Bonded NdFeB magnets are manufactured by blending isotropic rare-earth NdFeB powder with thermoplastic resins or thermoset epoxy binders. This composite matrix allows for a variety of shaping methods, delivering distinct mechanical and magnetic advantages:
Provides tolerances down to ±0.02mm, eliminating subsequent grinding processes and reducing overall material waste.
Allows thin-walled ring magnets, multi-pole integration, and overmolded assemblies that combine shafts or gears directly.
Exhibits superior mechanical properties with high resistance to cracking, chipping, and thermal shock compared to brittle sintered magnets.

The unique physical and chemical characteristics of Bonded NdFeB magnets make them essential across a wide spectrum of modern European technology sectors. Below, we highlight their key applications:
Luxembourg's automotive suppliers specialize in high-reliability components. Bonded NdFeB ring magnets are widely integrated into Electric Power Steering (EPS) systems, rotor assemblies, and position sensors. Their ability to deliver multi-pole magnetization profiles with precise transitions allows for high-accuracy angular detection and torque control.
As logistics and manufacturing facilities adopt automation, the need for compact, highly efficient motors grows. Injection-molded NdFeB magnets enable the production of micro-motors with high magnetic density and minimal weight, supporting precise movements in robotic joints, grippers, and linear guides.
Under initiatives like SpaceResources.lu, regional aerospace technology continues to expand. Bonded NdFeB magnets are selected for micro-thrusters, telemetry systems, and satellite mechanisms due to their geometric flexibility, high magnetic output, and low outgassing characteristics when treated with specialized vacuum coatings.
In renewable energy and high-efficiency motor design, custom-molded arc and block magnets help optimize magnetic flux lines, reducing cogging torque and maximizing electrical-to-mechanical conversion efficiency.
Find answers to common technical, logistics, and supply chain questions regarding Bonded NdFeB magnets.
Sintered NdFeB magnets are fully dense, brittle, and require extensive machining (slicing, grinding) to achieve final dimensions, but they provide the highest magnetic strength. Bonded NdFeB magnets incorporate polymer binders, enabling compression or injection molding of complex shapes, thin walls, and direct integration with gears or inserts. While their magnetic power is lower, they offer superior mechanical stability and dimensional precision.
Our raw material sourcing is directly integrated with major rare earth extraction and processing regions in China. Combined with our 5,000-ton annual capacity, this scale allows us to hedge against raw material price fluctuations. For European clients, particularly in Luxembourg, we establish shipping and regional warehousing frameworks to support consistent, long-term supply schedules.
Epoxy coatings (applied via electrophoretic deposition) are standard and offer excellent resistance to humidity and salt spray. For high-precision applications requiring minimal coating thickness, Parylene coatings provide uniform, thin-film protection against solvents, chemical exposure, and moisture.
Yes. We design and build custom magnetization fixtures in-house to produce skewed, radial, multi-pole, and custom halbach array magnetization patterns. This capability is critical for reducing cogging torque in high-performance brushless motors.
Absolutely. We perform routine chemical testing on our magnetic materials and coatings. Every batch shipped to the European Union, including Luxembourg, is accompanied by REACH and RoHS compliance documentation.
Whether you are designing a new automotive actuator, scaling robotic assembly lines in Luxembourg, or looking to optimize your magnetic component supply chain, our engineering team is here to assist.
