Explore our leading industrial permanent NdFeB assemblies, pot magnets, and specialized magnetic configurations.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has rapidly evolved from a visionary startup into an industry pacesetter in permanent magnets engineering. Our state-of-the-art manufacturing factory, sprawling across a massive 100,000 square meters in the vibrant tech cluster of Suining, Sichuan, serves as the engineering heart of our operations.
We work tirelessly to synthesize, process, and align high-performance rare earth NdFeB (Neodymium Iron Boron) materials, producing over 5,000 tons of custom magnetic configurations annually. Specializing in advanced types of magnetization—ranging from simple axial polarization to intricate multi-pole radial alignments—we ensure our products empower the world’s most demanding industrial sectors.
A comprehensive technical analysis of magnetic alignment vectorization for high-efficiency system integrations.
The magnetic orientation is aligned straight through the thickness or length of the magnet. Commonly used for disc, ring, and block shapes, axial polarization is standard for general applications, such as holding mechanisms, sensors, and basic solenoids. It ensures maximum holding force at the poles.
Magnetic alignment lines propagate from the center out towards the perimeter (or vice versa). Extremely critical for high-speed brushless electric vehicle (EV) traction motors, radial polarization maximizes air-gap flux density, improves torque output, and eliminates the structural weaknesses of multi-segmented arc rings.
Magnetized across the absolute width or diameter of a cylinder, ring, or disc. It is highly sought after by automation and aerospace industries for angle sensors, rotary encoders, and magnetic coupling assemblies where rotational vectors dictate circuit responses.
Generating multiple alternative North-South poles along a single surface of a ring or block. Ideal for micro-motors, precision encoders, and smart consumer items like MagSafe phone backings, where narrow magnetic pathways prevent field leakage into neighboring electronic components.
Advanced custom alignment where the magnetic path is intentionally skewed. Used in specialized electric motors to minimize cogging torque and acoustic vibration, delivering ultra-smooth rotation and long-term durability in automotive EPS applications.
Utilizing high-power capacitive discharge magnetizers (up to 4000V) and proprietary copper coil fixtures to embed intricate magnetic footprints into custom NdFeB assemblies, catering to proprietary aerospace and medical apparatus constraints.
Watch our technical demonstration showing how Zhejiang Laysun Magnetics processes high-performance sintered NdFeB blocks and cylinder magnets. We leverage specialized, computer-controlled hydrogen decrepitation, jet milling, and automated pressing systems under inert gas atmospheres to guarantee the highest magnetic energy product (BH)max and intrinsic coercivity (Hcj).
For global OEMs, procuring from a vertically integrated Chinese manufacturer like Zhejiang Laysun Magnetics Ltd. provides massive resilience. Over 80% of global rare earth processing originates in China. By placing our facility in Sichuan near primary deposits, we secure stable access to dysprosium (Dy), terbium (Tb), and neodymium (Nd) oxides. This enables competitive raw material pricing and mitigates global shipping delays.
Additionally, our 100,000 square meter factory utilizes advanced automated pressing equipment, reducing human error, guaranteeing high mechanical precision (tolerances as tight as +/- 0.05mm), and offering exceptional scaling capabilities for global enterprises requiring multi-ton shipments.
The modern motor and sensor industry is actively moving towards minimizing expensive and scarce heavy rare earths (Tb and Dy) without sacrificing high thermal stability. Zhejiang Laysun Magnetics utilizes grain boundary diffusion (GBD) technology. This process diffuses terbium or dysprosium only through the boundaries of the magnet grain, dramatically boosting the intrinsic coercivity (Hcj) up to EH and AH grades (withstanding up to 200°C) while keeping material costs optimized.
Our Quality Management Systems (QMS) align with strict automotive standards, certifying that every batch meets standard export criteria.
Certificates of compliance (ISO9001, IATF16949, RoHS, REACH) are available upon enterprise request.
