Explore our premium range of industrial rare earth magnets engineered for high-performance municipal and industrial waste separation machinery.
As municipal solid waste (MSW), electrical waste (WEEE), and industrial scraps scale exponentially, resource extraction efficiency has shifted from a regulatory chore to a highly lucrative trade. Magnetic Separation of Solid Waste stands at the epicenter of this industrial evolution, enabling the extraction of high-purity ferrous and non-ferrous fractions with microscopic precision.
By implementing advanced permanent magnetic circuits—primarily composed of premium Sintered Neodymium-Iron-Boron (NdFeB)—recovery operators can drastically cut energy requirements while maximizing separation throughput. Standard ferrite assemblies are rapidly being replaced by high-gradient NdFeB systems that ensure stable performance even under extreme temperatures and dusty environments.
Our solutions target maximum recovery metrics, empowering sorting plants to meet stringent global recycling mandates while safeguarding costly downstream processing equipment from catastrophic metal damage.
A National High-Tech Pioneer in Sintered Rare Earth Permanent Magnetic Solutions Since 1999.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has spent over two decades developing high-performance permanent magnetic components. Headquartered in Hangzhou, China, with a state-of-the-art production base spanning over 100,000 square meters in Suining, Sichuan, we deploy a team of 300+ engineering and manufacturing professionals to achieve an annual production capacity of 5,000 tons of rare earth magnets.
Our operation controls the entire NdFeB value chain, from raw material procurement to vacuum induction melting, jet milling, magnetic field pressing, vacuum sintering, and multi-axis CNC processing. This ensures that every magnetic core we supply to waste processing system integrators satisfies strict engineering tolerances.
Engineered for high-volume material streams, our advanced magnetic assemblies support multiple waste sorting methodologies.
Powered by high-frequency alternating magnetic rotors, our custom NdFeB arc segments generate powerful repulsion forces to efficiently eject non-ferrous metals like aluminum and copper from shredded inert materials.
Designed for heavy-duty extraction, these systems rely on large sintered NdFeB block magnets to pull tramp iron and structural ferrous components from deep bed depths on moving conveyor lines.
Equipped with a continuous 180-degree internal magnetic sector, our drum units offer automatic, uninterrupted self-cleaning profiles that ensure optimal extraction in high-wear abrasive processing plants.
Industrial procurement teams require more than basic magnet specs. In high-throughput solid waste facilities, separation systems face aggressive mechanical wear, varying ambient humidity, acid exposure, and severe temperature spikes.
Our engineering focus guarantees structural integrity and long-term magnetic field retention. By supplying high-purity raw materials, we achieve stable magnetization characteristics that sustain separator efficiency for decades. This lowers maintenance costs and keeps separation plants running smoothly.
Beyond municipal recycling, our rare earth magnetic solutions power crucial components in cutting-edge international tech markets.
To operate seamlessly in global supply chains, our production matches strict ISO and industry standards. Our internal quality control system oversees every stage, from checking incoming raw materials to inspecting magnetic flux output before delivery.
We maintain active credentials including ISO 9001 for quality management systems, ISO 14001 for environmental management, and ISO 45001 / OHSAS 18001 for occupational health and safety standards. Furthermore, we align with specific global directives like CE, API 6D, and TS standards, ensuring import compliance into European, North American, and Asian markets.

Technical insights into selecting and applying rare earth permanent magnets in sorting municipal and industrial solid waste.
Sintered Neodymium-Iron-Boron (NdFeB) magnets deliver a much higher energy product (BH max) compared to traditional ferrite magnets. This allows separators to generate stronger magnetic fields and deeper field reach. It is particularly critical for recovering small, lightweight non-ferrous particles in Eddy Current Separators or pulling heavy tramp iron through thick material layers on conveyor belts.
We add heavy rare earth elements, such as Dysprosium (Dy) and Terbium (Tb), to our NdFeB formulations to increase intrinsic coercivity. This prevents magnetic degradation even under high mechanical strain and operating temperatures up to 200°C. We also bake our magnets under vacuum sintering conditions to secure uniform crystal structures, preventing microscopic cracks caused by industrial vibration.
For standard dry systems, a multi-layer Electroplated Nickel-Copper-Nickel (Ni-Cu-Ni) coating offers robust impact and wear resistance. In highly humid or acidic waste setups, we apply a thick rubberized jacket, Epoxy coating, or encapsulate the assembly in hermetically sealed stainless steel (SUS304/SUS316) housings to prevent corrosion.
Yes. Our CNC grinding and multi-pole magnetization equipment allow us to produce complex arc segments, blocks, and ring profiles. We align magnetization direction (axial, radial, or custom multi-pole) to match the stator/rotor specs of your Eddy Current or Drum separator, optimizing performance.
