Welcome to Zhejiang Laysun Magnetics Ltd., your trusted partner in the world of advanced magnetic solutions. Since our inception in 1999, we have grown to become a national high-tech leader in manufacturing rare earth magnets, a testament to our unwavering commitment to excellence in this niche field.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has rapidly evolved from a visionary startup to an industry pacesetter. Our state-of-the-art factory, sprawling across 100,000 square meters in the vibrant city of Suining, Sichuan, is the heart of our operations. Here, our dedicated team of 300 employees works tirelessly to produce an impressive 5000 tons of rare earth magnets annually.
Specializing in the development, research, production, and sales of high-performance rare earth NdFeB magnets, we cater to a diverse range of applications. Our magnets are integral to various sectors, including electric vehicles, industrial motors, computers, and consumer electronics, enhancing the efficiency and performance of these technologies.
As a global hub for semiconductor packaging, aerospace component manufacturing, biomedical science, and smart city infrastructure, Singapore demands magnetic solutions that meet the highest standards of dimensional tolerance and physical durability. The nation's drive towards Industry 4.0 has prioritized components that support extreme precision, cleanroom operations, and minimised downtime.
Sintered Neodymium-Iron-Boron (NdFeB) magnets are critical enablers in Singapore's manufacturing sectors. From linear motors driving micro-positioning stages in lithography equipment to high-flux assemblies in HDD voice coil motors (VCM) and ultra-reliable brushless DC (BLDC) motors in smart automation, the performance parameters of NdFeB are non-negotiable. At Zhejiang Laysun Magnetics, we support Singapore-based OEMs and system integrators with tailored alloy formulations that address specific magnetic flux density and thermal resistance requirements.

How we maintain technological leadership to support complex global supply chains.
Our operational design relies on strict adherence to international quality management guidelines. By controlling the entire manufacturing process, from vacuum induction melting to grinding, machining, and surface coating, we ensure that every batch of neodymium magnets delivers consistent magnetic properties.
Leveraging Grain Boundary Diffusion (GBD) technology allows us to reduce the consumption of heavy rare earths (Dysprosium and Terbium) while significantly increasing the coercivity (Hcj) of our magnets. This innovation results in lighter, more temperature-resistant magnetic configurations.
Based near key Chinese logistic nodes (Hangzhou & Sichuan), we provide door-to-door air and ocean freight solutions straight to Singapore's industrial corridors, guaranteeing short lead times and streamlined customs clearance via the Changi Airfreight Centre and PSA terminals.
Global decarbonization efforts have placed high-efficiency permanent magnet synchronous motors (PMSM) at the center of the electric mobility revolution. EVs require NdFeB magnets that offer high magnetic field strength under extreme operating temperatures. In a standard EV drivetrain, magnets are exposed to temperatures exceeding 150°C, requiring SH, UH, or EH grades to prevent irreversible thermal demagnetization.
For large-scale infrastructure projects, such as offshore wind turbines, marine propulsion systems, and advanced robotics, the structural integrity of the permanent magnet is critical. Dynamic mechanical loads require precise structural shaping and uniform magnetization. At Zhejiang Laysun Magnetics, our sintering processes ensure density levels above 7.5 g/cm³, providing the mechanical strength necessary to withstand high centrifugal forces in high-rpm industrial motors.
Providing regulatory compliance, safety, and traceability for aerospace, automotive, and medical fields.
Operating in highly regulated industries requires compliance with strict global standards. Zhejiang Laysun Magnetics is certified under major quality and industry frameworks, including ISO 9001, ISO 14001, ISO 18001, CE, and TS/IATF 16949. If you need copies of our certifications or specific test reports (such as RoHS and REACH declarations), please contact our engineering support desk.
Singapore's hot and humid tropical climate, characterized by relative humidity levels frequently exceeding 80%, presents challenges for untreated sintered NdFeB magnets. Due to the high iron content in their Nd₂Fe₁₄B crystal structure, raw neodymium magnets are highly susceptible to oxidation and intergranular corrosion. This can lead to mechanical degradation and magnet demagnetization over time.
To address these challenges, our factory offers specialized surface treatments designed to withstand harsh marine and industrial environments:
While our advanced manufacturing centers are located in Hangzhou and Sichuan, China, we operate global logistics routes to serve the Asia-Pacific region. Singapore's status as a premier logistics hub enables us to supply components to manufacturers in Jurong, Woodlands, and Changi on a just-in-time (JIT) basis.
Our logistical frameworks support direct integration with our clients' supply chains, utilizing customized labeling, electronic data interchange (EDI), and direct-to-assembly delivery profiles.
The permanent magnet industry is shifting toward materials with lower environmental impact and higher magnetic efficiencies. Our technical roadmap focuses on three main development goals:
1. Heavy Rare Earth-Free (HRE-Free) High-Coercivity Magnets: Traditional high-temperature magnets rely on Dysprosium (Dy) and Terbium (Tb) additions. Our research team is developing chemical formulations that optimize grain size refinement to achieve SH/UH performance thresholds without relying on expensive, scarce heavy rare earths.
2. Circular Economy and Recycled NdFeB: We are building recycling initiatives that allow our customers to return end-of-life magnetic assemblies. Through chemical extraction and re-sintering processes, we can recycle rare earth oxides, reducing our environmental footprint while maintaining material performance.
3. Advanced Additive Manufacturing: We are exploring 3D printing techniques for polymer-bonded magnets, allowing engineers to prototype complex, multi-directional magnetic shapes that cannot be produced using traditional pressing and sintering methods.
