Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has evolved into an globally recognized high-tech pioneer in the synthesis, engineering, and manufacturing of custom rare earth permanent magnets. Over the past 25 years, our mission has been centered on addressing global engineering bottlenecks by providing extremely stable, customized supply chain solutions for advanced magnetic components.
Operating a state-of-the-art 100,000 m² manufacturing facility in Suining, Sichuan, and supported by our strategic international business office in Hangzhou, we operate a highly integrated technical system. With over 300 highly trained employees and an annual output capacity of over 5,000 tons of premium NdFeB magnetic materials, we guarantee high volume supply capabilities for mission-critical industries.
In the modern industrial environment, permanent magnets—particularly sintered Neodymium Iron Boron (NdFeB) materials—are essential for energy conversion. The rapid growth of vehicle electrification, renewable energy generation, and automation has led to complex supply chain requirements. As a result, companies have transitioned from traditional transaction-based purchasing to highly integrated inventory models.
Dynamic macroeconomic factors, raw material price shifts, and changes in environmental compliance standards have forced procurement teams to prioritize material traceability and supply continuity. Global OEMs now require partners to provide complete technical transparency, stable raw material sources, and reliable logistics buffer mechanisms. These capabilities are crucial to preventing production line shutdowns in high-demand fields like automotive EPS, wind power generation, and voice coil motor assembly.
Companies are moving away from Just-in-Time (JIT) delivery systems. Today's market demands strategic inventory structures that include local hub warehouses and bonded stock options. This approach helps buffer against unpredictable changes in shipping rates and transit timelines.
Modern compliance programs require detailed verification of raw materials. Responsible sourcing practices demand clear documentation of rare earth oxides from mine to magnet, ensuring compliance with global environmental standards.
To reduce dependence on heavy rare earths like Dysprosium (Dy) and Terbium (Tb), advanced producers use GBD technology. This process significantly improves magnet thermal stability while keeping material costs predictable.
Industrial applications demand long-term reliability. Advanced multilayer coatings—such as high-durability epoxy, chemical vapor deposition (CVD), and premium nickel-copper-nickel platings—are tested under strict pressure and salt-spray conditions.
We work with international logistics providers to support Vendor-Managed Inventory (VMI) structures and safety stock arrangements. This helps stabilize lead times and ensures a reliable supply of components during periods of high demand.
Our production facilities support a wide range of custom geometries, including precise block designs, complex arc segments, and thin-wall ring configurations. We use precision machining to meet strict dimensional tolerances of ±0.05mm or tighter.
We apply high-performance protective coatings—such as Nickel-Copper-Nickel, Zinc, Everlube, Epoxy, and Parylene—specifically formulated for harsh operating environments, preventing oxidation and premature degradation.
Our manufacturing sites utilize automated pressing systems, vacuum sintering furnaces, and multi-axis wire cutting machines to maintain consistent dimensional tolerances and magnetic properties. These systems ensure that block, arc, and cylinder magnets are processed to precise specifications.
Through systematic quality control, every batch of Neodymium magnets undergoes comprehensive testing—including demagnetization curve analysis, flux density measurements, and salt spray testing. This process verifies thermal resistance and magnetic stability before components are packed for international shipment.
Extending Grain Boundary Diffusion capabilities to reduce heavy rare earth content while achieving high thermal rating grades (such as UH, EH, AH).
Integrating 3D optical measurements and automated flux sorting systems into production lines to lower PPM defect rates to automotive standards.
Establishing regional inventory hubs in strategic international locations to support shorter transit times and just-in-time delivery capabilities.
Expanding rare earth recycling partnerships to offer eco-certified permanent magnets, supporting green procurement initiatives.
Operating as an expert manufacturer and exporter of rare earth magnets, we combine technical engineering with reliable supply chain management. By managing the entire production process internally—from raw material processing to final coating—we ensure high consistency in magnetic performance and batch-to-batch repeatability.
