Explore our high-performance NdFeB materials, precision-machined assemblies, and customized magnetic solutions engineered to exceed demanding industrial thresholds.
Zhejiang Laysun Magnetics Ltd. represents a pillar of high-capacity rare earth magnet production, delivering certified industrial performance worldwide.
Watch our operations in action. Our Sichuan-based factory deploys ultra-high-vacuum sintering ovens, automated multi-station precision slicing machines, and advanced physical vapor deposition (PVD) lines to ensure outstanding dimensional tolerances and magnetic stability.
Headquartered in Hangzhou, China, Zhejiang Laysun Magnetics Ltd. coordinates global supply routes via localized distribution networks, facilitating time-sensitive component access for automotive, consumer electronics, and heavy machinery markets.
Rare earth permanent magnets—specifically sintered neodymium-iron-boron (NdFeB) compounds—constitute the energetic baseline of modern electrification. As mechanical systems migrate toward ultra-dense power packaging, the choice of magnetic materials dictates systemic efficiency levels. At Zhejiang Laysun Magnetics Ltd., we translate physics into scalable industrial components. Since 1999, we have observed and directed the evolution of high-coercivity materials, positioning our manufacturing centers to mitigate operational risks across the global supply chain.
The global transition to a low-carbon economy relies on NdFeB magnets. These components provide high torque-to-weight ratios in electric motors, wind generator rotors, and automation systems. Industry projections indicate that demand for high-performance NdFeB magnets will grow substantially, driven by clean energy initiatives and automated manufacturing systems.
As industrial customers demand absolute consistency, raw material supply chain security is crucial. Zhejiang Laysun Magnetics Ltd. sources from key domestic mining hubs, ensuring a stable flow of neodymium, praseodymium, dysprosium, and terbium. Our strategic operations insulate clients from pricing spikes and raw material shortages, providing long-term predictability.
To reduce dependence on scarce heavy rare earth elements (HREEs) like Dysprosium (Dy) and Terbium (Tb) while maintaining coercivity, Laysun Magnetics has prioritized Grain Boundary Diffusion (GBD) technology. This metallurgical process introduces HREEs specifically along the boundary phases of the NdFeB grains rather than throughout the entire crystal matrix.
Advanced chemical controls restrict grain boundaries to sub-micron dimensions, elevating the nucleation resistance threshold against demagnetization fields.
GBD technology coats magnet surfaces with Dy/Tb compounds prior to heat treatments, allowing strategic penetration into the grain junctions without affecting internal remanence values.
Specialized physical vapor deposition (PVD) and electroplating lines apply ultra-thin layer protections like epoxy, zinc, and nickel-copper-nickel.
Our primary manufacturing complex covers 100,000 square meters in Suining, Sichuan, providing a highly integrated production ecosystem. This geographic location benefits from reliable access to regional raw material stockpiles and competitive operating costs. Unlike fragmented suppliers that outsource intermediate production, Laysun manages every step of the manufacturing cycle internally.
From initial vacuum induction melting (VIM) and hydrogen decrepitation (HD) to jet milling, transverse-field pressing, sintering, wire slicing, and automated plating, every stage is subjected to statistical process controls. This integration guarantees consistent performance profiles across high-volume production orders.
High-performance magnets operate under unique engineering challenges in the field. Our catalog is designed to meet these specific requirements:

Our quality management systems ensure our products meet standardized performance criteria before delivery.
Every batch of sintered NdFeB is subjected to testing protocols to verify its mechanical and magnetic profile. Our QC technicians use demagnetization curve tracers to verify remanence, coercivity, and maximum energy product ((BH)max) values.
To ensure durability in harsh environments, we conduct salt spray testing, highly accelerated temperature stress testing (HAST), and thermal cycling analysis to monitor coating integrity and prevent oxidation.
Our quality management is backed by verified ISO 9001, ISO 14001, CE, and industry-standard manufacturing certifications, ensuring reliable integration into global production processes.
