Directly shipped with full compliance documentation. Engineered for high mechanical stress, extreme thermal thresholds, and zero defect manufacturing.
Since our inception in 1999, Zhejiang Laysun Magnetics Ltd. has built an international footprint as a premier developer and high-volume manufacturer of rare earth NdFeB permanent magnets. Based in Hangzhou and utilizing a massive 100,000 m² modern factory layout, we supply advanced raw magnet components and tailor-made assemblies to the world's most demanding sectors.
From electric vehicle powertrains to offshore megawatt generators, our materials empower next-generation sustainable systems. Our streamlined direct-to-port supply routes regularly serve industrial clients across Lisbon, Setúbal, and Porto with optimized duty handling.
The metropolitan area of Lisbon, alongside adjacent manufacturing hubs like Setúbal and Palmela, is rapidly transforming into a cornerstone of Southern Europe's green technology and electromobility transition. Driven by the presence of large-scale automotive manufacturing complexes (such as Autoeuropa in Palmela), innovative startup incubators, and maritime wind energy developments, the demand for advanced sintered Neodymium-Iron-Boron (NdFeB) magnetic materials is witnessing a monumental rise.
Modern Electric Vehicles (EVs) rely heavily on high-performance permanent magnets for traction motors, electric power steering (EPS) systems, and sensory control units. The automotive clusters in Portugal operate on thin assembly windows, requiring zero-defect, high-coercivity NdFeB. Our block and ring magnets, specifically developed with Grain Boundary Diffusion (GBD) technology, minimize the usage of heavy rare earths (Dysprosium/Terbium) while ensuring thermal stability at temperatures exceeding 200°C.
Portugal's Atlantic coastline is a key deployment ground for offshore wind arrays. Wind turbines utilizing direct-drive permanent magnet generators (PMG) require massive quantities of custom NdFeB Arc Segments. These components face extreme moisture, salt corrosion, and structural vibration. By exporting magnets coated with advanced triple-layered Nickel-Copper-Nickel (Ni-Cu-Ni), Epoxy, or Everlube coatings, Laysun Magnetics ensures operational longevity of up to 25 years in harsh maritime environments.
European procurement departments maintain strict ESG and technical compliance barriers. Any magnetic materials entering Portugal must align with REACH regulations and RoHS restrictions on hazardous elements. Zhejiang Laysun Magnetics guarantees full traceability of raw materials and certified manufacturing processes (ISO 9001:2015, IATF 16949, and ISO 14001:2015). We supply comprehensive chemical declarations, demagnetization curves, and salt spray test sheets with every shipment batch to Lisbon customs ports.
From standard custom shapes to bespoke mechanical properties, we provide end-to-end support for rare-earth magnet integration.
We supply precision sintered blocks, rings, countersunk models, and complex arc shapes optimized to standard tolerances.
Our catalog covers premium NdFeB grades ranging from high-flux N35 up to N54, along with N48SH, N42UH, and extreme-grade N38AH.
Every industrial run undergoes automatic laser checking, magnetic flux testing, and oxygen content analyses for structural stability.
Verify which grade classification fits the thermal and magnetic requirements of your system.
