Explore our state-of-the-art permanent magnet products, meticulously manufactured to standard and custom specifications for precision industrial applications.
Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has evolved from a progressive domestic manufacturer into a recognized global enterprise in advanced rare earth technologies. As an official national high-tech leader, Laysun Magnetics specializes in the research, development, custom fabrication, and large-scale manufacturing of high-performance sintered and bonded Neodymium-Iron-Boron (NdFeB) magnet configurations.
Our world-class manufacturing center, spanning a massive 100,000 square meters in Suining, Sichuan, represents the heart of our production capacity. Driven by a dedicated engineering and operations team of 300+ professionals, Laysun outputs an impressive 5,000 tons of high-grade rare earth magnets annually. This massive scale ensures that we can satisfy the most demanding volume specifications from Tier-1 automotive, consumer electronic, and industrial automation enterprises worldwide.
At Zhejiang Laysun Magnetics Ltd., we employ state-of-the-art vacuum induction melting (VIM), strip casting, and hydrogen decrepitation technologies to refine raw rare earth materials into stable, ultra-fine powders. Our automated transverse and axial orientation presses then shape these materials before they enter our computer-controlled sintering furnaces.
Our core values—Quality, Credibility, Technology, and Innovation—guide every project we undertake. Rather than just acting as a vendor, we operate as a strategic co-engineering partner. We work with our customers to navigate complex magnet geometries, magnetic field requirements, and harsh environmental challenges.
As industrial motors and automotive power units demand higher operating temperatures and energy densities, traditional alloy methods for NdFeB magnets are reaching their thermodynamic limits. Heavy rare earth elements (HREEs) like Dysprosium (Dy) and Terbium (Tb) have traditionally been added to raise intrinsic coercivity (Hcj). However, this method often reduces remanence (Br) and increases raw material costs.
Instead of mixing expensive HREEs uniformly into the main phase alloy, our GBD process vaporizes and diffuses Dy/Tb directly along the grain boundaries after sintering. This increases the magnet's resistance to demagnetization while maintaining high remanence.
By optimizing the intergranular liquid phase using trace levels of Cobalt (Co), Copper (Cu), and Gallium (Ga), we improve structural stability at high temperatures. This ensures our SH, UH, and EH grade magnets can operate reliably at temperatures up to 220°C.
Through our closed-loop engineering program, we recover and process up to 98% of neodymium and dysprosium from manufacturing scrap. This helps reduce environmental impact and insulates our customers from raw material supply shocks.
We design and manufacture high-performance magnets tailored to the specific operational stresses of diverse global industries.
Sintered NdFeB blocks with high mechanical strength and thermal stability, optimized for EPS motors, traction drive motors, and sensor systems.
Precision-aligned arc segments and ring configurations that provide rapid response times and consistent flux in voice coil motors and servo drives.
Ultra-thin magnets, ring arrays, and MagSafe-compatible assemblies designed to fit within tight spaces inside mobile devices and acoustic systems.
Heavy-duty magnetic assemblies and lifting equipment designed to handle large metal structures and withstand tough industrial environments.
Our 100,000 m² production facility in Sichuan utilizes automated, data-driven manufacturing processes to maintain quality and reliability. By integrating automated material handling systems with smart PLC-controlled sintering ovens, we maintain uniform chemical composition and structural integrity across every production run.
This automated approach minimizes human error during the critical pressing and alignment stages. Combined with our direct partnerships with domestic rare earth refineries, we are able to maintain stable pricing and a secure material supply even during periods of global market volatility.
We streamline the path from initial engineering concept to series production, ensuring full regulatory compliance and reliable product performance.
We provide full verification documentation, including FMEA (Failure Mode and Effects Analysis), control plans, process flow diagrams, and dimensional reports to support automotive and medical product approvals.
Our engineering team uses advanced finite element analysis (FEA) software to model magnetic flux paths and predict potential thermal demagnetization issues before tooling begins.
We design custom magnetic shielding using double-walled steel containers and insulated packaging layouts to meet IATA guidelines for safe, interference-free air freight shipping.
Zhejiang Laysun Magnetics Ltd. maintains a comprehensive quality management system certified to international standards. Our manufacturing facilities are certified to API 6D, API 607, CE, ISO9001, ISO14001, and ISO18001 (TS/IATF 16949 compliant), ensuring consistent quality and performance across all product batches.
To support our partners worldwide, we offer end-to-end logistics solutions, including DDP (Delivered Duty Paid) shipping, custom clearance coordination, and localized warehousing. This allows our customers to minimize safety stock levels and simplify their import procedures.
All of our magnetic products are fully compliant with RoHS, REACH, and WEEE directives, guaranteeing the exclusion of hazardous substances and promoting environmental safety at every stage of the product lifecycle.
