Engineered to meet the exact high-retention structural specifications demanded by top enterprise operators and hardware distributors globally.
Serving as 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.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has rapidly evolved from a visionary startup into a global industry pacesetter. Our state-of-the-art manufacturing infrastructure is sprawling across 100,000 square meters in the vibrant tech corridor of Sichuan, housing some of the most advanced sintered NdFeB pressing and sintering furnaces in Asia. Here, our dedicated team of 300+ engineering and materials science experts produce an impressive 5,000 tons of high-grade rare earth magnets annually.
Specializing in the development, research, production, and sales of high-performance rare earth NdFeB magnets, we cater to a diverse range of high-demand applications. From dynamic voice coil motors (VCM) for digital tech to custom heavy-duty retention pot magnets comparable to the rugged retail standards found at systems like Screwfix, our components form the structural backbone of modern mechanical systems.
"Our relentless pursuit of technological advancement is not just about staying ahead of the curve; it's about setting new standards in the magnetics sector. We are deeply committed to exploring and harnessing the raw physics of rare earth element matrices, ensuring that our products support future clean-energy transitions."

Why industrial buyers demand direct OEM customization over off-the-shelf commercial alternatives like local retail outlets.
Industrial procurement professionals sourcing high-strength magnets for engineering projects face a common bottleneck: off-the-shelf items found in mass-consumer catalogs (such as regional hardware chains or general distributors like Screwfix) lack the customization, grading variations, and specific mechanical tolerances required for direct integration into production lines. Sintered Neodymium-Iron-Boron (NdFeB) material is highly susceptible to corrosion and thermal degradation if not specifically alloyed and coated for the operational environment.
Our OEM manufacturing model addresses this gap. By controlling the process from melt-spinning and sintering to wire-cut EDM styling, we supply products optimized for the precise mechanical load, spatial constraints, and magnetic path parameters of our clients' setups. Whether you require standard heavy-duty magnetic mounting pots, hook structures, or specialized multi-pole magnetic rings for high-RPM electric motors, our factory provides direct supply lines that outperform generic retail options at a fraction of unit costs.
High-grade anisotropic NdFeB segments that optimize rotational torque density in precise servo drives.
Ultralight, high-magnetic-energy-product components (up to 52 MGOe) for lightweight power-to-weight ratios in drones.
High-temperature co-efficient materials (grades SH, UH, EH, AH) designed to withstand extreme thermal cycles in traction motors.
Heavy-duty, vibration-resistant magnetic assemblies designed for robust containment in handheld tools.
Ultra-thin MagSafe assemblies, smart closures, and speaker voice coils customized with strict aesthetic coatings.
Efficient, low-noise compressor motor magnet segments optimized for modern HVAC and refrigeration technologies.
Mitigating mechanical wear, chemical oxidation, and high-temperature demagnetization.
One of the primary challenges with standard sintered NdFeB is the drop in coercivity at higher temperatures. Historically, this required adding significant amounts of costly heavy rare earth elements (HREEs) like Dysprosium (Dy) or Terbium (Tb) throughout the alloy. Our GBD technology diffuses Dy or Tb selectively along the grain boundary matrix rather than through the grain interior. This maintains magnetic core strength and boosts thermal limits up to 230°C while reducing dependency on volatile raw material markets.
Because raw neodymium is prone to oxidation in humid or marine environments, choosing the correct coating is crucial. Our state-of-the-art plating plant provides several custom solutions:
Our facility maintains strict compliance with ISO, API, and CE certifications, meeting the standards of demanding industrial buyers in Europe, the Americas, and APAC.
Quality is the cornerstone of our manufacturing process. We maintain strict compliance standards to ensure every batch of magnets meets your exact engineering requirements:
Clear answers to technical, logistical, and material questions to help you streamline the procurement process.
Retail hardware outlets like Screwfix typically supply a limited range of standard sizes and grades (usually lower N35 or N38 grades). Zhejiang Laysun Magnetics Ltd. provides comprehensive OEM customization, offering high-performance grades from N35 to N52, as well as high-temperature options (M, H, SH, UH, EH, AH). We also offer customized sizes, custom surface coatings (including rubber, Teflon, and epoxy), and full traceability required for aerospace, automotive, and industrial manufacturing.
We use automated magnetizing and flux-testing equipment alongside high-precision CNC machining to ensure dimensional tolerances within ±0.05mm. Every batch undergoes hysteresis graph testing and demagnetization curve verification, ensuring consistent magnetic field strength and performance across your entire production run.
For operations below 80°C, standard N-series (up to N52) magnets are suitable. For higher temperatures, we recommend our specialized heat-resistant grades: H-series (up to 120°C), SH-series (up to 150°C), UH-series (up to 180°C), or EH-series (up to 200°C). For extreme automotive and aerospace requirements, our AH-series operates reliably up to 230°C.
