Explore our top-tier magnetic solutions engineered to withstand critical environments and maximize efficiency.
In the rapidly evolving landscape of advanced engineering, Neodymium Iron Boron (NdFeB) rare earth permanent magnets stand as the quiet enablers of the green technology revolution. Characterized by unparalleled maximum energy product ($BH_{max}$) and high coercivity, these materials represent the pinnacle of modern magnetic performance. From the micro-actuators within smartphones to the massive multi-megawatt direct-drive generators of offshore wind turbines, the efficiency and size optimization of modern systems depend directly on the quality and stability of permanent magnet materials.
Zhejiang Laysun Magnetics Ltd., founded at the turn of the millennium in 1999, has spent more than two decades at the forefront of this critical industry. As a national high-tech enterprise, we integrate research, production, coating, and testing to supply premium magnetic solutions to automotive, industrial automation, and consumer electronics markets globally.
"Our corporate roadmap focuses on bridging structural engineering challenges with chemical design, leveraging advanced metallurgy, state-of-the-art grain boundary refinement, and customized coating application to deliver absolute reliability."
Our core manufacturing center in Suining, Sichuan, represents the height of automated processing technology. Every step of our production workflow—from vacuum induction melting and strip casting to hydrogen decrepitation, jet milling, alignment compaction, sintering, and machining—is closely monitored using advanced automated sensor arrays.

Why global procurement teams rely on Laysun Magnetics to secure their high-performance magnet supply chain.
Today's rare earth procurement managers face a volatile landscape marked by fluctuating commodity prices (specifically Praseodymium-Neodymium, Dysprosium, and Terbium) and strict trace-compliance regulations. In industries such as automotive electrification and aerospace manufacturing, material selection is no longer just about selecting a grade off a spec sheet; it is about securing a long-term supply relationship that ensures absolute chemical consistency.
Laysun Magnetics addresses these concerns directly. Our 5000-ton annual output acts as a cushion against sudden market surges, ensuring a steady inventory pipeline for high-volume OEMs. Additionally, we work closely with tier-1 engineering groups to develop custom NdFeB magnet shapes that optimize flux patterns while minimizing scrap rate. Our state-of-the-art facilities offer wire-cutting, high-precision grinding, and custom profiles to match tight geometric tolerances (typically +/- 0.05mm or narrower upon demand).
Different operating environments require specific mechanical and magnetic attributes. We specialize in tailoring material properties across four major industrial sectors:
To tackle the supply limits and high costs of heavy rare earths (HRE) like Dysprosium (Dy) and Terbium (Tb), Laysun Magnetics has developed and put into production advanced Grain Boundary Diffusion (GBD) technology.
By selectively diffusing Dy or Tb along the grain boundaries of sintered magnets rather than alloying them throughout the entire grain core, we can:
Our manufacturing lines are certified to global automotive and environmental standards, ensuring compliance across international supply chains.
We employ strict quality control protocols at each phase of manufacturing:
