High-performance permanent magnet systems engineered for strict industrial tolerances and robust environmental resistance.
How micro-scale surface chemistry and high-gradient magnetic fields optimize downstream extraction and sorting protocols.
Magnetic separation chemistry relies on high-coercivity rare earth magnets like Neodymium-Iron-Boron (NdFeB) to construct localized, high-gradient magnetic fields. By focusing magnetic flux, we enable the clean immobilization of superparamagnetic iron oxide nanoparticles (SPIONs) in complex chemical matrices.
The chemistry at the interface is critical. Sintered magnets are custom coated to prevent heavy metal leaching while facilitating functional surface modifications. Whether functionalized with silica, carboxyl groups, or streptavidin, our magnets support high-throughput chemiluminescence immunoassay (CLIA) systems.
Biological and separation environments expose NdFeB magnets to acids, bases, and aqueous buffers. Our advanced plating technologies—including multi-layer Nickel-Copper-Nickel (Ni-Cu-Ni), Parylene, PTFE, and industrial-grade rubber—ensure structural integrity, zero contamination, and long-term operating durability.
In modern nucleic acid purification and biomolecule assays, magnetic separation chemistry replaces slow, traditional centrifugation. Superparamagnetic microparticles are suspended in solutions containing DNA, RNA, or target proteins. When our custom-designed high-flux NdFeB blocks are brought into proximity, the particles migrate rapidly to the container wall. Our OEM magnetic racks and arrays provide uniform pull force across multi-well plates, reducing cycle times and preventing target loss.
Your Global Partner for Advanced Magnetic Solutions Since 1999
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has evolved from a pioneering startup into a recognized national high-tech leader in the rare-earth permanent magnet industry. Headquartered in the logistics hub of Hangzhou, China, we operate a state-of-the-art production base spanning 100,000 square meters in Suining, Sichuan.
Our dedicated team of 300 professionals is committed to driving the frontier of rare-earth magnetic design. With an annual manufacturing capacity of 5,000 tons, we supply high-performance NdFeB magnets to key industrial segments, including electric vehicles (EVs), wind turbines, industrial robotics, precision motors, and medical diagnostics.
Mapping the future of rare-earth magnetic applications from 2025 to 2030.
Precision brushless DC (BLDC) motors and robotic joints require high-density sintered magnets with tight physical and magnetic tolerances. As manufacturing demands rise, our magnets provide high torque-to-weight ratios to support fast, energy-efficient robotic operations.
Electric vehicle drivetrains and Electronic Power Steering (EPS) systems require high-coercivity NdFeB segments that can operate in high-temperature environments. We utilize heavy rare earth grain boundary diffusion (GBD) technology to optimize Dy/Tb efficiency and cost.
High-gradient magnetic separation chemistry is essential for targeted diagnostics. Our custom separation blocks and racks are designed to generate high magnetic field gradients, allowing for quick biomagnetic collection in DNA extraction and immunoassay systems.
In response to evolving industrial demands, Zhejiang Laysun Magnetics Ltd. is pursuing key technical milestones:
