Explore our custom-engineered NdFeB components manufactured for global durability and extreme environments.
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 5,000 tons of rare earth magnets annually.
Tamil Nadu has established itself as the powerhouse of advanced electronics, automotive components, and heavy engineering in India. Industrial complexes in Chennai, Sriperumbudur, Oragadam, Coimbatore, and Hosur require reliable high-performance rare-earth magnetic solutions. Custom Neodymium (NdFeB) magnets are the critical hardware components driving the transition towards Electric Vehicles (EVs), next-generation wind turbines, automation machinery, and voice coil motors (VCMs).
For engineers and procurement managers across Tamil Nadu, obtaining a clear pricelist while assuring quality compliance is crucial. Neodymium magnets are highly susceptible to fluctuations in raw material pricing (specifically Praseodymium-Neodymium alloy) and are sensitive to thermal degradation. Working directly with an experienced Chinese high-tech manufacturer like Zhejiang Laysun Magnetics Ltd. provides the ideal balance between cost-efficiency, custom engineering, and material reliability.
Sourcing directly from our 100,000 square meter facility in China offers major strategic advantages to Tamil industrial enterprises. With a complete supply chain running from mine to finished magnet, Zhejiang Laysun Magnetics Ltd. guarantees stability and quality control:
China refines over 85% of the world's rare earth elements. We secure raw material components directly, insulating our clients from extreme price volatility on NdFeB alloy compounds.
Our automated chemical line provides high-level corrosion resistance. Choose between multi-layer Nickel-Copper-Nickel (Ni-Cu-Ni), Epoxy, Teflon, Rubber encapsulations, and custom Parylene coatings.
Using state-of-the-art wire cutting, slicing, and grinding machines, we routinely maintain tight dimensional tolerances of +/- 0.05 mm, and up to +/- 0.02 mm for critical aerospace and automotive setups.
The global magnetics industry is currently going through a technological shift aimed at reducing dependency on Heavy Rare Earths (HRE) such as Dysprosium (Dy) and Terbium (Tb). Our R&D department at Laysun Magnetics utilizes Grain Boundary Diffusion (GBD) technology. This process allows us to increase the coercivity of N52 and N54 grades to survive high thermal limits (up to 200°C) without compromising on the high energy product (BH)max. This is a game-changer for motor manufacturers looking to build smaller, lighter, and more powerful equipment.
| Magnetic Grade Class | Max Working Temp (°C) | Remanence Br (kG) | Intrinsic Coercivity Hcj (kOe) | Primary Industrial Sector |
|---|---|---|---|---|
| N35 - N52 (Standard) | 80 | 11.7 - 14.8 | ≥ 12 | Sensors, consumer electronics, hooks, magnetic separators |
| M Series | 100 | 11.4 - 14.2 | ≥ 14 | Acoustic transducers, micro motors, magnetic rings |
| H Series | 120 | 11.1 - 13.8 | ≥ 17 | Automotive EPS, VCM, high efficiency home appliances |
| SH Series | 150 | 10.8 - 13.4 | ≥ 20 | Wind turbines, brushless DC motors, industrial automation |
| UH / EH Series | 180 - 200 | 10.2 - 12.8 | ≥ 25 | EV Traction motors, Aerospace alternators, high-heat pumps |
Zhejiang Laysun Magnetics Ltd. works to meet international standards. We supply industries where safety and performance parameters cannot be compromised. Our manufacturing workflows are certified against:
Through these certifications, we verify that our magnetic materials meet design specifications. This helps engineering teams in Chennai and global hubs avoid issues with thermal demagnetization or plating degradation down the line.
Laysun Neodymium Magnets are integrated into premium applications globally, driving efficiency in diverse fields.
Ultra-precise NdFeB ring and block segments for high-torque servo motors, collaborative robotic arms, and industrial assembly systems.
Lightweight NdFeB arc magnets designed to maximize the thrust-to-weight ratio of high-RPM brushless drone motors.
Automotive-grade magnets engineered for EV traction motors, regenerative braking setups, and steering assist (EPS) systems.
High impact-resistance NdFeB elements supplying permanent excitation fields for handheld drills, grinders, and heavy assembly drivers.
Micro-magnets, ring arrays for MagSafe devices, laptop hinge dampeners, and voice coil motor magnets for smartphones.
Inverter air-conditioner compressors, smart refrigerators, and washing machine drum drives using high-efficiency NdFeB rotor structures.
Headquartered in Hangzhou, China, Eneroc and Laysun Magnetics are building worldwide subsidiaries and offices to serve our customers. From our advanced base, we ship magnetic materials directly to major industrial hubs including the Chennai Port (Tamil Nadu, India), Port of Rotterdam, Hamburg, and US West Coast ports.
Our commitment to excellence is verified by independent auditing bodies. Our facility maintains full compliance certificates: API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, TS. We welcome third-party inspections (SGS, TÜV Rheinland) prior to dispatching volume orders.
The cost of a custom Neodymium magnet order is determined by several variables, rather than a single metric. To optimize procurement budgets, engineers should understand how these design variables impact final pricing:
