Precision-engineered rare earth permanent magnets tailored for separation vessels, chemical filtration, and automation processes.
Industrial chemistry has entered an era of micro-refining, where efficiency is defined at the sub-micron scale. At the center of this transformation is Chemistry Magnetic Separation, a foundational methodology utilized to separate targeted phase components from liquid-phase matrices. This physical purification process operates on the principal interaction of high-gradient magnetic fields and particles displaying ferromagnetic or paramagnetic susceptibilities. The applications range from recovery of expensive homogenous catalysts, removal of heavy-metal precipitates from industrial waste channels, to precise biomolecule isolation within pharmaceutical batch processing.
By bypassing conventional, energy-intensive filtration loops, gravity settling, or solvent-heavy extractions, magnetic separation streamlines process configurations. Modern industrial setups rely heavily on high-coercivity rare earth magnets. Through customized spatial arrangements, these magnets construct high-gradient magnetic fields (HGMS) that capture nanoparticles or mineral phases even under high-viscosity or volatile flow parameters. Zhejiang Laysun Magnetics Ltd. has consistently supplied global engineers with customizable NdFeB arrays designed to resist thermal stress and chemical decay, securing operational durability across volatile fluid streams.
The standard challenge faced during chemical magnetic separations is the vulnerability of Sintered NdFeB magnets to environmental corrosives. Exposure to weak acids, alkaline cleaning phases, and organic solvents can initiate structural oxidization of the neodymium-rich phase. This vulnerability demands specialized surface barrier coatings. Laysun Magnetics counters this engineering issue by manufacturing assemblies protected by multi-layer Nickel-Copper-Nickel (Ni-Cu-Ni), chemical-vapor deposited Parylene, fluoropolymer (PTFE) encapsulations, or thick rubber-molded barriers.
These surface barrier designs are tailored directly to prevent magnetic leakage, chemical ingress, and mechanical degradation. In bio-separation setups, biocompatible coatings prevent toxic ion leakage into sample mediums, ensuring protein fractionation or DNA extraction cycles proceed without trace metal contamination.
Founded in 1999, Zhejiang Laysun Magnetics Ltd. is a national high-tech enterprise dedicated to research, manufacturing, and global export of rare earth NdFeB permanent magnetic materials.
Certification Portfolio: ISO9001, ISO14001, ISO18001, TS16949, CE compliance.
Addressing complex production bottlenecks across processing, mining, and advanced battery chemistry.
Processing channels in raw mineral extraction rely on wet processing circuits. Laysun’s magnetic separators facilitate high-throughput tailing separation and recovery of paramagnetic heavy mineral fractions, reducing downstream filtration demands.
In chemical synthesis loops containing precious metals (Pd, Pt, Rh) supported on magnetic carbon cores, our magnets ensure total recovery of the active phases. This cuts down process loss rates and reduces raw material reinvestments.
Enabling reliable magnetic bead manipulation in clinical diagnostic labs. Laysun manufactures micro-magnetic arrays that facilitate high-throughput automated nucleic acid separation with consistent field geometry.

How Laysun is pushing boundaries in magnetics research to meet tomorrow's challenging processing demands.
To reduce raw material dependencies, our research team is developing grain boundary diffusion (GBD) technologies. This allows us to achieve high-coercivity grades without depending on expensive dysprosium (Dy) and terbium (Tb) additives.
We are refining injection-molding systems for advanced PTFE encapsulations. The goal is to build micro-separator components that can operate continuously inside strong inorganic acid matrices without degradation.
Modern high-load motors and chemical processes generate high operating temperatures. Our technical roadmap focuses on securing high thermal-stability parameters (UH and EH grades) that maintain magnetic field strength under constant thermal stress.
