High-performance permanent magnets engineered to meet exact industrial and medical design specifications.
Zhejiang Laysun Magnetics Ltd. is 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.
Our state-of-the-art manufacturing processes allow us to produce high-grade sintered NdFeB magnets that serve critical applications globally. One of our key focus areas includes the development and OEM customization of Silver Safe Magnetic Therapy solutions. By combining the biocompatibility and anti-microbial properties of pure silver plating with the extreme flux density of modern rare earth neodymium magnets, we deliver medical-grade magnetic components that are both safe for prolonged skin contact and highly effective in bio-magnetic therapy applications.
Exploring the convergence of rare earth magnetic engineering and modern physiological wellness devices.
Traditional nickel plating poses allergic risks on skin. OEM Silver Plating (Ag) ensures hypoallergenic properties and excellent antimicrobial performance, critical for wellness wearables.
With consumer electronics shifting towards micro-wearable health devices, high-grade NdFeB magnets provide the maximum possible magnetic field density in ultra-thin form factors.
The global shift towards non-toxic health components requires manufacturing lines capable of lead-free, REACH-compliant processes, ensuring the raw materials match clinical safety limits.
Founded at the turn of the millennium, 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.
Core Values: At Laysun Magnetics, our ethos is built on four pillars - Quality, Credibility, Technology, and Innovation. These values are the cornerstones of our operations, guiding us in delivering products that not only meet but exceed the expectations of our global clients.
Commitment to Innovation: Our relentless pursuit of technological advancement is not just about staying ahead of the curve; it's about setting new standards in the magnetic field. We are deeply committed to exploring and harnessing the potential of rare earth magnets, ensuring that our products not only serve current needs but also pave the way for future medical, industrial, and consumer innovations.
Meeting the strict quality control, testing protocols, and compliance frameworks of international enterprises.
Our processes are certified to API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, and IATF 16949 standards, ensuring complete tractability and quality alignment.
For silver safe magnetic therapies, we execute strict cross-cut adhesion tests and salt spray chamber runs to guarantee the silver barrier remains stable under human sweat and humidity.
With 5,000 tons of annual rare earth output, we guarantee long-term price stability and uncompromised supply scheduling for mass-market hardware launches.
Leveraging automated sintering, precise EDM slicing, and advanced electroplating lines for ultimate reliability.
Zhejiang Laysun Magnetics Ltd. utilizes Factory 4.0 infrastructure to control every stage of raw material synthesis. Starting from the raw rare-earth materials (Neodymium, Iron, Boron), we execute vacuum induction melting, strip casting, hydrogen decrepitation, and jet milling under strict inert gas environments. This guarantees our NdFeB blocks have uniform grain sizes, achieving the top thresholds of BH(max) and high temperature resistance.
Our electroplating workshops employ state-of-the-art multi-layer protective coating applications. For therapeutic, biomedical, and consumer contact applications, we apply a high-purity silver coating over a nickel or copper base, ensuring the magnet maintains structural integrity and presents no hazardous chemical exposure.
