High-precision custom geometries engineered for extreme environments and industrial duty cycles.
Establishing Standards of Excellence in Advanced Magnetic Components Since 1999
As a national high-tech enterprise, Zhejiang Laysun Magnetics Ltd. represents the peak of manufacturing precision in China's rare earth magnet supply chain. We specialize in the R&D, manufacturing, and global exportation of top-grade sintered Neodymium-Iron-Boron (NdFeB) and custom magnetic systems. Based out of our massive manufacturing headquarters in Suining, Sichuan, and supported by global management hubs in Hangzhou, we provide the technical foundation for EV motors, high-frequency robotics, consumer electronics, and green energy applications.
The permanent magnet sector is undergoing a profound paradigm shift driven by the requirements of global decarbonization, structural efficiency demands, and geopolitical supply chain restructuring. Advanced NdFeB systems have largely replaced legacy AlNiCo and SmCo systems in areas where maximum energy density (BH)max and spatial efficiency are paramount.
Did you know? Heavy Rare Earth Elements (HREEs) like Dysprosium (Dy) and Terbium (Tb) are now applied via Grain Boundary Diffusion (GBD) technology, increasing thermal stability while saving up to 70% of precious HREEs compared to traditional bulk alloying methods.
Key development vectors in the industry include:
Procurement managers face multidimensional decisions when purchasing permanent magnet steel. Standard off-the-shelf options rarely satisfy the strict tolerances required by aerospace, automotive, or robotics companies. Consequently, exporters must offer robust custom design support.
Detailed breakdown of raw material indices (PrNd, DyFe, Tb) ensuring transparent, fair value pricing matrices.
Strict adherence to ISO 9001 and IATF 16949 standards to ensure a 0 PPM defect rate for automotive lines.
Custom flux values, coercivity margins, and tight geometrical tolerances within +/-0.02mm.
Zhejiang Laysun Magnetics' 100,000 square meter factory in Suining, Sichuan, represents the integration of Factory 4.0 paradigms. Modern manufacturing requires more than raw tonnage; it demands a resilient supply chain and high dimensional accuracy.
By situating our core production facilities in Sichuan, Laysun Magnetics leverages the region's clean hydroelectric power resources, significantly reducing the carbon footprint of our operations. Additionally, raw material sourcing is secured through direct agreements with primary rare-earth processing facilities, protecting our production plans from external market disruption.
Understanding local engineering requirements is essential. Laysun Magnetics manufactures customized shapes designed for specific target systems:
Compliant with major quality management standards for critical engineering applications
Laysun Magnetics operates with a strong commitment to quality. Our processes conform to ISO 9001, ISO 14001, ISO 18001, and IATF 16949 standards. This focus allows us to supply challenging markets such as Europe, North America, and East Asia with reliable magnetic materials.
Addressing engineering challenges and procurement concerns in the rare earth magnet supply chain.
The cost of permanent NdFeB magnets is heavily dependent on the price of rare earth elements (PrNd, DyFe, Tb). These make up over 70% of the material costs. Other factors include the level of geometric complexity, tolerances, surface coating requirements (e.g., standard Ni-Cu-Ni vs. high-protection epoxy/Parylene), and bulk volume tiers.
We use advanced Grain Boundary Diffusion (GBD) technology. This process diffuses Dysprosium or Terbium into the magnet’s boundaries, enhancing temperature performance (up to H, SH, UH, EH, AH classes) without compromising raw remanence. Our quality control processes verify flux output consistency across production runs.
We provide a variety of protective coatings. Options include standard Ni-Cu-Ni plating, black/grey epoxy, rubber coating, tin/gold plating, and Parylene coatings. These finishes help protect the underlying NdFeB material from humidity, chemical exposure, and oxidation.
Standard custom prototype lead times are 2-3 weeks, with full-scale production orders completed in 4-6 weeks. We support sea, air, and express transport options. Our shipping methods comply with IATA regulations for magnet safety packaging, ensuring cargo does not interfere with aircraft navigation systems.
Yes. We offer custom orientation patterns, including axial, radial, multipolar, diametrical, and skewed orientations. These custom configurations are designed to optimize magnetic performance in specific rotor, sensor, and stator applications.
High-performance solutions designed for consumer electronics, automotive EPS, and voice coil motors.
