Explore our highly integrated industrial magnetic components, custom sintered for micro-assemblies, heavy machinery, and precision electro-acoustic transducers.
The rapid global migration toward electrification and consumer electronic miniaturization has catalyzed an unprecedented demand for high-density, thin-profile magnetic configurations. Traditionally, thin NdFeB configurations were plagued by high demagnetization vulnerabilities and severe mechanical fragility. As a premium manufacturer and global exporter, Zhejiang Laysun Magnetics Ltd. has spent over two decades engineering advanced sintered neodymium compositions that deliver massive magnetic energy products (BHmax) even when sliced to sub-millimeter thickness.
By utilizing revolutionary metallurgical processing technologies, such as Grain Boundary Diffusion (GBD) of heavy rare earth elements (Dy/Tb), our thin magnets exhibit superior intrinsic coercivity (Hcj) and stable operations up to high threshold temperatures. This guarantees that your sensors, motors, and high-fidelity actuators remain exceptionally thin without sacrificing operational stability or thermal performance.
Establishing stable, massive manufacturing baselines to fuel global hardware ecosystems since 1999.
Established in 1999 at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has systematically transformed from a specialized metallurgical workshop to an internationally recognized, state-level high-tech enterprise. Our modern production lines, situated across a massive 100,000 square meter facility in Suining, Sichuan, contain complete vertical processes—from vacuum induction melting, strip casting, hydrogen decrepitation, and jet milling to inert gas sintering and precision machining.
Our core operations are strategically managed from our global commerce and logistics headquarters in Hangzhou, China. By positioning our primary logistics node in this metropolitan hub, we streamline export pathways to key target markets across North America, the European Union, and Southeast Asia.
Deploying micro-profile magnetic technology into active global application hubs, from automotive arrays to consumer haptics.
Thin neodymium discs and circles act as haptic engines, voice coil motors (VCM) for optical autofocus, and MagSafe accessories in modern smartphones. Their lightweight construction helps manufacturers optimize internal device spacing.
High-temperature NdFeB arc segments are deployed in Electric Power Steering (EPS) and traction motors. Using thin, segmented layers effectively curtails eddy current losses, preventing thermal runaways under heavy load conditions.
Thin magnets provide massive torque outputs inside the joint brushless motors of robotic arms and surgical tools. They allow micro-actuators to deliver quick, high-acceleration responses in space-limited environments.
When permanent magnets are manufactured with an extremely low thickness-to-diameter ratio, the self-demagnetizing field within the magnet spikes. To counteract this physics-based challenge, Laysun Magnetics optimizes the alignment of the crystal grains along the easy axis of magnetization during the pressing phase.
This strict control process produces high-remanence thin profiles that hold their magnetic properties even in presence of opposing demagnetizing fields. This makes them ideal for precision sensors, high-performance haptics, and industrial applications.
Unlocking higher temperature ranges and thinner profiles through cutting-edge chemical engineering.
Neodymium magnets are highly reactive and vulnerable to oxidation. This vulnerability is magnified in ultra-thin structures where the surface-area-to-volume ratio is high. Standard coatings like Nickel-Copper-Nickel (Ni-Cu-Ni) are effective, but Laysun has expanded options to include Parylene and Epoxy barriers.
Parylene coating is applied through vapor deposition polymerization to create a highly conformal, pinhole-free layer. This technique provides excellent moisture protection at thicknesses below 10 micrometers, which prevents changes to critical design tolerances in precision electronics.
Our engineering team employs Grain Boundary Diffusion (GBD) technology to optimize the use of heavy rare earths like Dysprosium (Dy) and Terbium (Tb). Rather than mixing these expensive elements uniformly through the core alloy, we diffuse them selectively along the grain boundaries.
This approach isolates Dy and Tb exactly where demagnetization begins, strengthening the magnet's thermal performance and coercivity while conserving valuable remanence (Br) in the core crystal structure.
Securing reliable component sourcing through vertical material integration and robust logistics.
China manages a significant portion of the world's rare earth mining, refining, and alloy processing. By operating our primary sintering plant in Sichuan and shipping from Hangzhou, Laysun keeps operations close to vital raw material suppliers.
This close proximity shields our clients from volatile global pricing spikes, resource constraints, and transport interruptions that can affect long-distance supply routes.
With a production capacity of 5,000 tons per year, we handle bulk wholesale orders with stable lead times. Our manufacturing runs utilize advanced automation, reducing labor-dependent bottlenecks and ensuring consistency across high-volume production batches.
We maintain certified manufacturing practices to meet global compliance regulations across heavy industry, aerospace, and medical sectors.
Our quality systems meet demanding international standards, including API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, and TS classifications. We provide complete material traceability and certificate documentation for automotive and high-reliability aerospace products.
