High-performance magnetic solutions engineered to meeting strict space and thickness constraints.
In modern industrial design, the relentless push toward miniaturization requires components that are lighter, thinner, yet magnetically superior. Zhejiang Laysun Magnetics Ltd. stands at the forefront of this technological shift. By exploiting advanced powder metallurgy and proprietary sintering processes, we manufacture ultra-thin neodymium (NdFeB) magnets that bypass traditional mechanical thickness limitations.
Standard neodymium magnets are historically prone to chipping and structural failure when sliced below 1.0 mm. Our advanced manufacturing facility, however, utilizes specialized multi-wire slicing technology and high-precision double-disk grinding to safely deliver consistent thickness down to 0.2 mm with tolerances within ±0.01 mm.
Maintaining high coercivity at sub-millimeter scales requires complex chemical balancing. We incorporate Grain Boundary Diffusion (GBD) technologies, strategically diffusing Dysprosium (Dy) or Terbium (Tb) through the crystal grain boundaries. This process dramatically increases intrinsic coercivity ($H_{cj}$) without sacrificing remanence ($B_r$), making our super thin components highly resistant to thermal demagnetization in tight, enclosed electronic designs.
Procuring ultra-thin magnets requires custom material verification. Standard N52 grade materials suffer structural weakness at sub-millimeter thickness. Laysun’s technical teams consult directly with R&D engineers to match the ideal grade (e.g., N52H, N48SH, or N42UH) depending on operational temperatures and demagnetization stress.
Super thin magnets present high surface-area-to-volume ratios, making them vulnerable to environmental oxidation. We utilize state-of-the-art coating configurations, including electroplated Nickel-Copper-Nickel (NiCuNi), chemical-resistant Epoxy, and ultra-thin vapor-deposited Parylene, to provide chemical barrier protection down to 10 microns.
Zhejiang Laysun Magnetics operates a massive 100,000 m² production base in Suining, Sichuan. This geographic proximity to raw rare-earth mining operations allows us to bypass intermediate logistics bottlenecks, secure competitive material costs, and guarantee a steady 5,000-ton annual supply for global accounts.
At Zhejiang Laysun Magnetics, our business model is built on four core values: Quality, Credibility, Technology, and Innovation. Rather than acting as a simple catalog vendor, we operate as a specialized design partner. Our internal testing labs utilize Helium Pycnometry for density verification, Permeameters to plot hysteresis curves, and Highly Accelerated Stress Testing (HAST) to confirm product longevity under heat and pressure.
This systematic scientific approach is why tier-1 global manufacturers trust our super thin magnets. From early-stage prototyping to full-rate manufacturing of up to 5,000 tons annually, our engineering teams ensure every batch displays identical magnetic properties, eliminating variation in your automated assembly processes.
Our NdFeB solutions power advanced technologies across critical modern industries.

In the highly regulated automotive, aerospace, and medical device fields, product compliance is non-negotiable. Zhejiang Laysun Magnetics operates in strict compliance with ISO 9001 and IATF 16949 automotive quality management criteria.
Our magnets comply with global environmental directives, including RoHS (Restriction of Hazardous Substances), REACH, and WEEE. We perform rigorous analytical chemistry checks to guarantee the absolute absence of restricted heavy metals or volatile contaminants. Our products are exported with complete trace certificates, outlining the path from primary mine ore all the way to finalized custom component packaging.
To support global supply chains, we operate regional distribution hubs and administrative offices. This lets us coordinate custom warehousing, manage local import/export regulations, and guarantee rapid delivery timelines across North America, Europe, and the Asia-Pacific region.
Fully compliant with international safety, environmental, and performance standards.
As next-generation products demand thinner layouts and higher thermal tolerances, Zhejiang Laysun Magnetics continues to push the boundaries of magnetic metallurgy. Our long-term research is centered on three core developments:
To reduce dependence on scarce Dy and Tb minerals, we are pioneering advanced grain-refinement techniques that achieve high thermal stability and coercivity without using heavy rare earths. This helps stabilize costs and improves supply chain sustainability.
Our micro-precision laboratories are currently test-running slicing processes designed to scale down to 0.15 mm thickness. This will support upcoming consumer electronics applications like next-generation smart glasses, advanced medical implants, and ultra-thin micro-sensors.
We are establishing processing systems designed to reclaim and re-refine neodymium magnets from end-of-life electronics. This recycled NdFeB retains identical magnetic performance while reducing the carbon footprint of the manufacturing process.
