Explore our top-performing industrial neodymium rare earth magnets engineered for high-durability salvaging, voice coil motor systems, MagSafe rings, and custom mechanical integrations.
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.
Headquartered in Hangzhou, China, 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.
We specialize in the development, research, production, and sales of high-performance rare earth NdFeB magnets, catering to a diverse range of applications. Our magnets are integral to various sectors, including electric vehicles, industrial motors, computers, consumer electronics, and specialized recovery applications like magnet fishing.
An in-depth analysis of NdFeB microstructures, pull force calculation models, magnetic circuit maximization, and extreme-environment coatings.
Sintered Neodymium-Iron-Boron (NdFeB) is categorized by its maximum energy product (BH)max, ranging from N35 to N52. Higher grades yield greater magnetic flux densities, but require precision alloying with Dysprosium (Dy) and Terbium (Tb) to resist thermal demagnetization in heavy industrial applications.
Bare neodymium magnets have omnidirectional flux lines. By encasing the NdFeB block within a precision carbon steel cup (known as a Pot Magnet configuration), the magnetic flux lines are redirected and concentrated onto a single active face. This loop amplification increases the magnetic hold up to 400%.
In aquatic environments, NdFeB is highly susceptible to oxidation. Our proprietary Ni-Cu-Ni (Nickel-Copper-Nickel) electroplating process, combined with a final layer of water-resistant black epoxy or polyurethane, creates a barrier that prevents saltwater degradation and structural peeling.
In testing conditions, "Pull Force" refers to the perpendicular tension required to separate the magnet from a flat, polished structural steel plate. In real-world retrieval, user experience dictates that "Shear Force" (lateral sliding force) is significantly lower—often only 15% to 25% of the rated pull force. By utilizing premium N52 grade cores and optimizing the steel cup wall thickness, Zhejiang Laysun Magnetics maximizes the vertical force vector while providing rugged mechanical housings that safeguard the internal magnet from impact cracking.
From environmental remediation of historic waterways to industrial recovery inside mining boreholes and offshore oil rigs.
In regions such as Western Europe (e.g., the UK canals, German rivers) and North America (Great Lakes region), magnetic fishing has evolved from a recreational hobby into an essential ecological cleanup activity. Volunteers and municipal agencies use our NdFeB pot magnets to retrieve heavy structural metallic wastes, discarded bicycles, ancient weapons, and safe boxes from deep sediments, reducing pollution and clearing navigation channels.
Deep borehole drilling and maritime oil extraction require highly specialized retrieval tools to clear lost drill bits, steel fasteners, and broken tools (often referred to as "fishing for junk"). Standard mechanical grapples fail on smooth, cylindrical surfaces. Our high-grade custom NdFeB assembly lifters solve this problem by generating immense localized magnetic fields capable of pulling steel elements out of thick mud and high-pressure oil reservoirs.
As a premier rare earth magnet exporter based in Zhejiang, Laysun Magnetics utilizes China's highly integrated supply chain ecosystem. Approximately 70% of the world's rare earth smelting and separation occurs in China, providing us direct access to high-purity Neodymium-Praseodymium (NdPr) metals without international shipping bottlenecks.
By managing the production cycle end-to-end—from initial vacuum induction melting and strip casting to hydrogen decrepitation, jet milling, magnetic field alignment pressing, and vacuum sintering—we reduce cost overheads by 30% compared to Western competitors. This structural advantage allows us to offer premium, low-cost (cheap) fishing magnets to global wholesalers while maintaining rigorous quality control metrics.
