Premium Magnetic Materials Designed to Power Industrial & Consumer Innovation
Executive Summary on Rare Earth Materials in Global Consumer Electronics
In the highly competitive landscape of global consumer electronics, precision engineering is the defining factor for success. Modern smart devices, electric vehicles (EVs), automation equipment, and consumer audio systems require increasingly powerful, smaller, and more thermally stable components. At the center of these hardware technological leaps is the Neodymium-Iron-Boron (NdFeB) magnet.
As a leading national high-tech enterprise, Zhejiang Laysun Magnetics Ltd. has been at the forefront of researching, developing, and manufacturing high-performance sintered and bonded NdFeB magnets since 1999. Through state-of-the-art metallurgical technologies, grain boundary engineering, and automated production, we supply standard and custom magnetic configurations that meet the strict requirements of international OEM/ODM clients.
Two Decades of Solid Manufacturing Excellence and Technical Innovation
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has evolved from a regional visionary startup into an international industry pacesetter. Our state-of-the-art factory in Sichuan is the heart of our operations, supplying key global sectors.
We specialize in the engineering, R&D, and custom fabrication of high-coercivity and high-remanence rare earth magnets. From voice coil motor (VCM) components to automotive EPS, our solutions optimize efficiency.
Operating under the four core pillars of Quality, Credibility, Technology, and Innovation, we exceed standard certifications. Our internal QC labs test magnetic properties under extreme thermal and corrosive conditions.
Exploring High-Temperature Coercivity and Miniaturization Trends
The consumer electronics industry is moving toward thinner, lighter, and more power-efficient devices. This trend demands miniature magnetic solutions that maintain high magnetic flux densities under elevated temperatures. The Laysun technical roadmap focus on three key material science breakthroughs:
By diffusing Heavy Rare Earth elements (such as Dysprosium, Dy, or Terbium, Tb) into the grain boundary rather than alloying the whole magnet, we achieve high coercivity (Hcj) while minimizing raw material cost and maintaining high remanence (Br).
Consumer electronics require magnets that resist sweat, humidity, and atmospheric corrosive elements. We develop advanced multilayered electroplating techniques, including nickel-copper-nickel (Ni-Cu-Ni), parylene, epoxy, and customized dual-coating formulas.
Modern wireless chargers (like smartphone magnetic ring arrays) and smart wearables require complex multi-polar magnetizations. Our advanced magnetization fixtures enable high-precision multi-pole alignment in sintered and bonded magnets.
Translating High-Performance Materials into System-Level Hardware Success
Robotic joint actuators require servo motors with high torque density and low cogging torque. Sintered NdFeB arc segments and ring magnets allow compact motor footprints, enabling precise movement in collaborative robots (cobots) and warehouse logistics systems.
Voice coil motors (VCM) in camera autofocus assemblies and high-fidelity micro-speakers require tight dimensional tolerances (+/-0.01mm) and high field homogeneity. Our precision disc and custom-molded block magnets ensure smooth autofocus and clear sound reproduction.
Sintered block magnets are the main component in modern EV permanent magnet synchronous motors (PMSM). Operating in environments up to 200°C, these magnets must resist demagnetization. Laysun supplies high-coercivity (UH, EH, AH grades) magnets to global tier-1 automotive suppliers.
