Explore our premium grade NdFeB and neodymium permanent magnets engineered for optimal performance and maximum energy density.
In the contemporary landscape of high-precision engineering, clean tech energy transitions, and robotics, Rare Earth Magnets represent the critical material baseline. Sintered Neodymium-Iron-Boron (NdFeB) magnets deliver the highest maximum energy product ((BH)max) of any commercially available material, enabling intense miniaturization and exceptional energy-efficiency profiles.
Globally, procurement managers face tightening regulatory environments, demands for traceability, and high volatility in rare earth element (REE) price indexes (particularly Neodymium, Praseodymium, Dysprosium, and Terbium). Securing a reliable factory partner capable of balancing consistent magnet grades, structural integrity, and stable contractual pricelists is no longer just a purchasing requirement—it is a strategic imperative.
As industry experts, Zhejiang Laysun Magnetics Ltd. provides an integrated model. Operating at the core of the raw material processing cluster in China, we manage supply-chain volatility directly, extending cost benefits and high-purity guarantees to international partners across aerospace, automotive, electronics, and industrial automation sectors.
Our 25-year structural journey underpins our engineering authority, large-scale output capability, and technological consistency.
Founded in 1999, Zhejiang Laysun Magnetics Ltd. has evolved from a targeted enterprise focused on basic magnetic materials into a national high-tech powerhouse. Headquartered in Hangzhou, China, our advanced production hub is strategically positioned across a massive 100,000 square meter facility in Suining, Sichuan. This geographic positioning leverages adjacent mineral purification hubs and high-capacity green hydroelectric power grids, optimizing production costs and rendering our commercial pricelists highly resilient to global energy market fluctuations.
Currently, our dedicated workforce of 300+ professionals, which includes a leading team of materials scientists and metallurgical engineers, maintains an annual output capacity of 5,000 tons. Our primary directive focuses on the synthesis, machining, and surface coating of sintered NdFeB magnets, ensuring reliable operation under high-stress and harsh industrial applications.
Understanding the efficiencies, technology hubs, and structural factors driving high-quality magnet production.
From extraction, separation of raw oxides, alloy manufacturing (melting and strip casting), to final processing, the Chinese industry is fully integrated, reducing transport overheads and lead times.
Applying state-of-the-art Grain Boundary Diffusion (GBD) technology. This process significantly reduces the requirement for expensive heavy rare earth elements (Dy, Tb) while maintaining high coercivity (Hcj) at high operating temperatures.
Massive 100,000 m² setups combined with automated slicing, wire cutting, and high-efficiency double-sided grinding machineries optimize yield and reduce overall unit prices for global purchasers.
Every batch of raw alloy is verified by Inductively Coupled Plasma (ICP) spectroscopy and hysteresisgraphs. We ensure complete performance parity to global standards (DIN, ISO, ASTM).
We dedicate 5% of annual revenue to developing specialized coating systems (Everlube, Parylene, Zinc, Nickel-Copper-Nickel) to improve corrosion resistance in extreme marine and automotive environments.
Focusing on reducing carbon emissions during manufacturing, recycling scrap material, and adhering to strict ISO14001 guidelines to build a sustainable green energy supply chain.
Our manufacturing catalog details precise configurations of customized NdFeB geometries adapted to customer specifications.
How Laysun Magnetics powers the core components of tomorrow's physical and digital infrastructure.
When engineering advanced drive systems or structural magnetic holds, selecting the correct production method is vital. Sintered Neodymium magnets undergo a powder metallurgy process: casting the raw alloy, pulverizing the materials to micron-sized particles, orienting the powder under a magnetic field, and sintering the blanks to consolidate the matrix. This offers the absolute highest magnetic energy density, making it ideal for automotive traction motors and wind turbine rotors.
Bonded Neodymium magnets, on the other hand, are composite materials formed by blending NdFeB powder with binders (epoxy or nylon), then injection molding or compression molding the mixture. While they offer much lower magnetic properties, they allow for complex net-shapes directly out of the tooling, without secondary grinding, saving total cost for applications like fan motors and sensor assemblies.
