Explore our high-precision NdFeB standard and custom-engineered magnetic product portfolio, designed specifically for robotics integration, high-performance servomotors, and electric drivetrains.
Since our establishment in 1999, Zhejiang Laysun Magnetics Ltd. has built an industry-leading reputation as a premier national high-tech manufacturing enterprise specializing in high-performance sintered and bonded NdFeB magnets. We stand committed to developing magnetics designed for the demanding requirements of global robotics, automotive drive systems, aerospace instrumentation, and energy transmission systems.
Headquartered in Hangzhou, China, our advanced production hub spans an impressive 100,000 square meters in Suining, Sichuan. Anchored by a workforce of over 300 experienced professionals and engineering specialists, we maintain a robust annual output of 5,000 tons. Through scientific execution and strict precision processes, we ensure that every batch of magnetic components demonstrates excellent temperature stability, coercivity, and spatial flux uniformity.
The global paradigm of industrial manufacturing is undergoing a profound structural shift driven by artificial intelligence, cyber-physical networks, and advanced kinematic design. At the core of this transition lies the robotics and automation sector, which demands unprecedented levels of efficiency, torque density, and positional accuracy. Rare earth permanent magnets—particularly sintered Neodymium-Iron-Boron (NdFeB)—are the fundamental building blocks of modern automation. These materials provide the essential magnetic field energy required by high-power density servomotors, frameless torque motors, linear actuators, and magnetic grippers.
According to global industry database analysis, the demand for high-grade NdFeB magnets in robotic joints (cobots, humanoid robots, and automated guided vehicles) is projected to grow at a CAGR of 18.5% over the next decade. Standardizing procurement specifications through an enterprise Robotics and Automation Letter ensures supply chain robustness, technical compliance, and cost predictability.
Industries across Europe, North America, and East Asia are aggressively localizing automated infrastructure to mitigate labor shortages and enhance manufacturing precision. In Germany, the Industry 4.0 initiative has accelerated the integration of collaborative robots (cobots) that operate alongside humans. These systems rely on specialized magnetic configurations—such as custom bonded NdFeB ring magnets—to operate high-resolution magnetic rotary encoders for real-time positional telemetry. Meanwhile, in North America, massive distribution networks are scaling up Autonomous Mobile Robots (AMRs) and Automated Guided Vehicles (AGVs) that utilize heavy-duty permanent magnet DC motors and magnetic track guidance systems to achieve 24/7 logistical uptime.
Understanding downstream application trends is essential to optimizing magnet specifications. Our research and development focuses on three primary vectors of innovation:
Next-generation actuators demand higher torque output within increasingly compact spaces. This trend requires the application of ultra-high-grade magnets (such as N52, N54, and N52H) that exhibit massive maximum energy products ((BH)max) without increasing the physical volume of the rotor assembly.
To mitigate the risk of high-temperature demagnetization in heavy industrial environments, we utilize advanced Grain Boundary Diffusion. By diffusing heavy rare earths (Dysprosium or Terbium) selectively along grain boundaries, we dramatically increase coercivity (Hcj) while preserving high remanence (Br).
Robotic systems frequently operate in harsh manufacturing, agricultural, or marine environments. We engineer specialized protective coatings—including multi-layer Nickel-Copper-Nickel (Ni-Cu-Ni), high-durability Epoxy, and custom Rubber-jacketed structures—to prevent oxidation and mechanical degradation.

Rare earth magnets do not operate in isolation; they are highly customized to adapt to the environmental and dynamic requirements of local markets and specific application segments:
In German and Japanese automotive assembly lines, cobots require frameless brushless DC torque motors built with high-coercivity NdFeB segments. The magnetic circuit must minimize cogging torque to ensure smooth kinematic movement and micro-radian structural adjustment tolerances.
Massive logistics networks require heavy-duty AGV drive motors capable of constant torque delivery under varying payloads. High-performance sintered NdFeB blocks with robust protective coatings are optimized to withstand heavy thermal loads and mechanical shock.
Precision surgery requires ultra-miniaturized actuators with high-precision feedback loops. Biocompatible coatings and high-purity bonded magnets are critical to operating safe, reliable, and noise-free motion profiles in sensitive environments.
As automation demands evolve, our product engineering roadmap targets the next generation of electromagnetic challenges. Over the next three to five years, our primary R&D vectors focus on material efficiency, environmental sustainability, and performance boundary testing:
Reducing reliance on critical heavy rare earths (Dysprosium and Terbium) by advancing grain refinement techniques. This ensures stable raw material cost structures for large procurement contracts without compromising thermal threshold safety margins.
Developing commercial-grade 3D printing methodologies for complex magnetic shapes. This enables custom multipolar field profiles that are impossible to generate using traditional compression molding or sintering processes.
Establishing closed-loop recycling networks to recover sintered NdFeB from end-of-life industrial robots, processing it back into high-purity magnetic powder with minimal environmental footprint.
