Your trusted partner in the world of advanced rare earth magnetic solutions.
Since our inception in 1999, Zhejiang Laysun Magnetics Ltd. has grown to become a national high-tech leader in manufacturing rare earth magnets. This is a testament to our unwavering commitment to excellence in this highly specialized scientific field. Sprawling across 100,000 square meters of state-of-the-art factory area in Suining, Sichuan, we integrate advanced research, automated production, and customized engineering to supply global industries with robust magnetic technologies.
Our company focuses exclusively on high-performance rare earth NdFeB magnets, providing high-efficiency supply networks, structural consistency, and deep engineering support. With over two decades of technical evolution, we empower key global technologies across electric vehicles, clean energy power generation, and advanced aerospace sensors.
The core engine behind electrification, automation, and green transition.
Neodymium-Iron-Boron (NdFeB) magnets represent the pinnacle of modern permanent magnet technology. Boasting the highest energy product (BHmax) of any commercially available magnetic material, Neodymium magnets deliver unmatched energy density. This unique property makes them critical to the global shift toward decarbonization and industrial automation. Today, custom Neodymium magnets are no longer simple off-the-shelf commodities; they are custom-engineered precision components.
Currently, the global demand for Neodymium magnets is surging. The exponential growth of the Electric Vehicle (EV) industry, renewable wind power generation, micro-motors in consumer electronics, and smart industrial robotics drives this market. In wind energy turbines, particularly offshore direct-drive systems, permanent magnet generators rely on tons of NdFeB magnets to convert kinetic energy into grid-ready electricity.
Modern applications require thermal thresholds up to 230°C (AH, EH, UH grades) to prevent thermal demagnetization in heavy-duty electric powertrains.
Specialized coatings like Ni-Cu-Ni, epoxy, Zn, and protective rubber layers are essential to ensure the longevity of neodymium magnets in humid or acidic environments.
Micro-manufacturing techniques enable the production of complex, multi-pole radial rings, segment arcs, and ultra-thin blocks for high-density magnetic arrays.
Furthermore, geopolitics and resource localization have highlighted the importance of supply chain resilience. Procurement directors in Europe, North America, and Japan are shifting from spot buying to strategic partnerships with integrated manufacturers. This guarantees a steady supply of heavy rare earth elements like Dysprosium (Dy) and Terbium (Tb), which are crucial for maintaining magnetic stability under extreme thermal stresses.
Watch our state-of-the-art rare earth manufacturing line in action. We combine automated powder metallurgy, high-pressure compacting under magnetic fields, and precise sintering processes to produce up to 5,000 tons of rare earth magnets annually.
Each batch undergoes strict testing, including demagnetization curve analysis, salt spray testing for coating longevity, and dimensional scanning to guarantee adherence to tolerances within ±0.05mm.
Unrivaled vertical integration, high-tech automation, and scale economies.
China is the global powerhouse for rare earth magnet production, accounting for over 80% of the world's NdFeB magnet output. This dominance is not based solely on mineral reserves; it is driven by an incredibly sophisticated, vertically integrated manufacturing ecosystem. Zhejiang Laysun Magnetics Ltd., with its primary production hub in Sichuan, leverages this ecosystem to offer unmatched advantages to global buyers:
Providing high-precision magnet configurations engineered for real-world operations.
EV traction motors demand sintered NdFeB blocks with high coercivity and resistance to thermal stress. Our magnets provide stable torque and high power efficiency, helping extend vehicle driving range.
Servo motors in industrial robotic arms require lightweight magnets with exceptional magnetic density. Our custom segmented arcs ensure smooth rotation and precise positioning.
Used in hard drives and high-resolution camera focusing mechanisms, our micro-precision voice coil motor magnets deliver swift, stable linear actuation under continuous duty cycles.
Ultra-thin ring magnets, such as custom MagSafe-compatible smartphone arrays, require precise structural integrity, corrosion resistance, and safe, consistent magnetic attraction.
Pot magnets, rubber-coated holding systems, and heavy-duty magnetic hooks provide secure structural lifting, workholding, and magnetic separation across harsh assembly environments.
Direct-drive wind turbines require massive arrays of high-stability NdFeB segments. Our advanced grain boundary diffusion (GBD) technology significantly reduces the requirement for expensive heavy rare earths while maintaining high thermal thresholds.
