High-performance permanent rare earth NdFeB architectures built for absolute magnetic field consistency and minimal flux degradation.
Zhejiang Laysun Magnetics Ltd. represents the vanguard of rare earth manufacturing innovation. As a nationally certified high-tech enterprise, we design, develop, and market high-performance sintered NdFeB magnets and advanced magnetization assemblies. Our mission is to engineer high-energy solutions that sustain complex workflows in modern automotive, automation, and aerospace systems.
For more than two decades, we have partnered with global tier-1 suppliers to replace legacy electromagnetic arrays with highly integrated, rare earth units. The Magnetization Emu G classification indicates a proprietary calibration protocol that optimizes the magnetic domain alignment of permanent magnets. This results in minimal flux drift, high magnetic field homogeneity, and optimized performance in extreme thermodynamic environments.
How Laysun Magnetics navigates the thermodynamic and electromagnetic challenges of high-energy permanent magnets.
To reduce dependence on heavy rare earths like Dysprosium (Dy) and Terbium (Tb), Laysun has integrated a high-purity GBD processing method. By localized spraying and subsequent vacuum diffusion heat treatment, we deposit critical elements directly along the grain boundary junctions. This process preserves magnetic coercivity (Hcj) in high-temperature environments (up to 220°C) while maintaining maximum residual induction (Br).
Modern servo control and EPS systems demand strict sinusoidal flux distributions. Laysun’s in-house calibration facility features advanced multi-pole radial magnetizing fixtures, capable of handling complex magnetic geometries. This system ensures less than 0.5% pole-to-pole magnetic deviation, stabilizing output performance and reducing cogging torque.
By 2026, Laysun aims to introduce a closed-loop recycling program for rare earth magnetics, aiming to recover up to 25% of neodymium scrap directly from internal machining residues and client partnerships. Sintering furnace energy inputs are also optimized through intelligent load-balancing software, minimizing emissions per ton of magnet produced.
Optimizing industrial performance: High-grade permanent magnetics developed for global, demanding application fields.
We supply high-coercivity sintered NdFeB segments for EV traction motors and electronic power steering (EPS). These materials offer thermal stability, keeping system efficiency high even at heavy operational loads.
High-torque servo motors require small footprint magnets with high energy density. Laysun’s block and arc segments help automate robotic arms and control systems with precision.
Lightweight motor designs rely on high energy product (BH)max magnets. Our advanced sintering formulas support payload capacity and stability for unmanned aerial vehicles (UAVs).
Handheld power tools need drop-resistant, vibration-proof magnetic assemblies. Our polymer-jacketed and custom metal pot magnets provide long-term protection under impact.
Our micro-magnetic rings and discs are engineered for cellular devices, smart acoustic hardware, and wireless chargers, ensuring clean coupling connections.
Smart, energy-efficient compressors, water pump motors, and ventilation systems rely on our durable NdFeB solutions to achieve high ratings for power consumption and longevity.
Laysun Magnetics operates a modern 100,000 m² manufacturing plant in Suining, Sichuan. This facility integrates advanced raw material processing, vacuum induction melting (VIM), hydrogen decrepitation, jet milling, and automated compression molding under inert gas protection. Locating the plant in Sichuan provides raw material security and allows us to utilize clean hydroelectric power to run our operations.
To ensure high quality, we track every batch from mining raw materials to the final magnetized state using digital tracing systems. This gives buyers clear visibility into performance metrics and material quality, helping to stabilize their global supply chain.
Multi-wire slicing machines control thickness tolerances down to ±0.02mm, reducing raw material waste.
Continuous electroplating lines apply NiCuNi, Zinc, Epoxy, and chemical coatings for long-term corrosion protection.
Non-destructive testing (NDT) checks for internal micro-cracks and voiding to ensure mechanical integrity under stress.
Ensuring reliability and technical compliance at every step of the procurement process.
We support B2B clients with Advanced Product Quality Planning (APQP) and standard Production Part Approval Processes (PPAP level 1-5). This step simplifies custom part integration into automotive supply chains.
Our engineers adjust tools for arc segments, custom rings, multipolar rings, and specialized assemblies. We aim to keep first-article inspection (FAI) cycles short, reducing lead times.
We test our products using environmental chambers and hysteresis graphs. We measure flux density variations at elevated temperatures to confirm the stability of the magnets under specified conditions.
