Explore high-performance Neodymium magnets engineered for precision performance across automotive, industrial, and consumer applications.
Founded in 1999 at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has evolved from an ambitious high-tech startup into an industry-leading manufacturer of advanced rare earth permanent magnets. Our headquarters in Hangzhou, China, along with our massive manufacturing complex, forms a core hub for global magnetic materials engineering.
We specialize in the complete lifecycle of high-performance rare earth NdFeB (Neodymium Iron Boron) magnets: from advanced research & development to large-scale precision fabrication and worldwide distribution. Over more than two decades, we have gained a reputation for delivering reliable and custom-engineered magnetic solutions to enterprise customers globally.
Why Modern B2B Procurement Teams Bridge the Gap Between Fast Digital Supply Hubs and Advanced Custom Production Lines
Many R&D engineers use retail hubs like Shopee for quick prototype validation. However, as production scales, direct integration with a certified supplier like Zhejiang Laysun Magnetics ensures consistent magnetic flux, tighter tolerances (+/-0.01mm), and custom protective coatings.
Off-the-shelf Neodymium magnets often fail to state detailed thermal parameters. We support specific mechanical requests ranging from Standard N35 to N52, and high-temp variants like M, H, SH, UH, EH, and AH series, which resist demagnetization at up to 220°C.
Buying direct minimizes intermediate vendor markups. We support custom JIT (Just-in-Time) delivery, container planning, custom outer packaging, and safe air/sea transport shield containers, meeting strict IATA and maritime transport guidelines.
Zhejiang Laysun Magnetics Ltd. operates a high-capacity manufacturing base in Suining, Sichuan, spanning an extensive 100,000 square meters. Our production lines feature vacuum induction melting furnaces, hydrogen decrepitation systems, jet mills, and isostatic pressing machinery.
By controlling the raw material processing stage through to final surface treatment, we ensure high quality at scale. Our facilities deliver a yearly production of 5,000 tons of rare earth NdFeB magnets. This scale allows us to support both large OEM orders and initial prototype builds with minimal lead times.
Powering advanced technologies globally. From clean energy vehicles to precision micro-automation.
Neodymium magnets are crucial for modern EV powertrains. We manufacture high-coercivity NdFeB block magnets optimized for Traction Motors and Automotive Electric Power Steering (EPS). These materials offer reliable torque output under thermal and vibrational stress.
Precision brushless DC (BLDC) motors in multi-axis robotic joints and drones require magnets with low cogging torque and high magnetic energy density. Our multi-pole bonded NdFeB ring magnets help developers build lighter, highly responsive rotor assemblies.
From thin MagSafe phone rings to voice coil motors (VCM) for optical autofocus, we deliver high-performance micro-magnets. These products feature specialized coatings like multi-layer Ni-Cu-Ni or organic epoxy to protect against environmental wear.
Our research and development team is focused on improving the performance parameters of NdFeB materials while reducing dependency on heavy rare earth (HRE) materials. Our technical roadmap addresses three key design requirements:
We introduce heavy rare earths like Dysprosium (Dy) or Terbium (Tb) only at the grain boundaries. This technique raises the intrinsic coercivity (Hcj) of the magnet while preserving high remanence (Br), optimizing performance-to-cost ratios.
Sintered NdFeB is prone to oxidation. We offer custom surface finishes, including chemical vapor deposition (CVD), chemical nickel plating, double-layer epoxy, and rubber coatings to meet salt spray test (SST) standards of up to 72 hours.
Equipped with multi-wire cutting machines and automatic grinding units, we shape complex arc segments, counterbore holes, and customized micro-geometries down to +/-0.03mm tolerances.
Providing magnetic materials tailored to challenging environmental conditions and performance criteria.
Our sales and logistics network in Hangzhou coordinates international shipping, custom clearance, and localized technical support.
To support global supply chains, our export operations prepare custom packaging designed to bypass high magnetic field interference during air shipping, complying fully with IATA regulations. We handle documentation for customs requirements in North America, Europe, Southeast Asia, and South America.
Our production operates under certified quality management systems: ISO9001, ISO14001, ISO18001, API 6D, API 607, CE, and TS/IATF 16949 standards.

Technical and logistics guidance for procurement leads, supply chain managers, and engineers.
Shopee is useful for quick consumer purchases and fast prototype testing. However, B2B procurement from Zhejiang Laysun Magnetics provides access to structural materials testing, customized dimensions, compliance certificates (RoHS, REACH, IATF 16949), and optimized batch-to-batch consistency. We support custom orders with specified thermal behavior and magnetic parameters.
Standard Neodymium magnets (N-series) operate up to 80°C (176°F). For high-temperature environments, we offer custom-formulated alloys: M (100°C), H (120°C), SH (150°C), UH (180°C), EH (200°C), and AH (220°C). We use Grain Boundary Diffusion (GBD) to enhance temperature limits while minimizing the use of costly heavy rare earth metals.
We apply several coatings depending on the application environment. These include Standard Triple-layer Nickel-Copper-Nickel (Ni-Cu-Ni), Epoxy Coating (for high humidity), Zinc (Zn) plating, Gold/Silver plating, and custom Rubber-coated covers that provide mechanical protection and slip resistance.
We follow strict quality planning procedures (APQP), submit Production Part Approval Process (PPAP) documentation, and run FMEA (Failure Mode and Effects Analysis) cycles. Our testing lab tests performance variables like demagnetization behavior, dimensional values, and coating thickness, ensuring we deliver parts that meet strict automotive standards.
