High-performance permanent magnets engineered to meet exact industrial standards. Explore our core configurations for Portugal's high-tech manufacturing, aerospace, and energy transition sectors.
Portugal is fast becoming a pivotal clean-energy and technology hub in Southwestern Europe. With key investments in offshore wind energy projects, a rapidly growing electric vehicle supply chain (centered near Lisbon, Setúbal, and Porto), and a precision machinery market, the domestic demand for highly reliable NdFeB Neodymium magnets has scaled exponentially.
While local sourcing channels in Portugal support prototype developments, direct manufacturing at scale requires the robust metallurgical infrastructure, supply security, and state-of-the-art manufacturing of a leading global supplier. Zhejiang Laysun Magnetics Ltd. provides the critical bridge between China’s unrivaled rare-earth processing capabilities and the rigorous quality standards demanded by Portuguese industries.
From wind turbine generator components to automotive Electronic Power Steering (EPS) and voice coil motors (VCM) for high-end electronics, we deliver customized magnetic solutions that guarantee structural integrity under extreme thermal and mechanical stresses.
Since 1999, Laysun Magnetics has driven advancements in rare earth metallurgy. Our high-tech manufacturing capacity translates into unmatched security of supply and design excellence for our international partners.
Our flagship manufacturing facility located in Sichuan sits adjacent to rich mineral corridors, enabling vertical integration that insulates our Portuguese and European clients from market volatility while keeping chemical purity at optimal levels.
Sintered Neodymium-Iron-Boron (NdFeB) represents the pinnacle of modern magnetics. For precision mechanical engineering applications across Portugal's industrial belts in Porto, Aveiro, and Setúbal, understanding thermal stability thresholds, magnetic coercivity ($H_{cj}$), and corrosion resistance profiles is vital.

Neodymium magnets are inherently prone to oxidation. In Portugal's humid maritime and coastal environments, proper coating selection is critical. We provide specialized coatings including:
Procuring custom NdFeB rare earth magnets from an offshore manufacturer demands rigorous logistical control, quality certifications, and secure logistics channels. For procurement directors operating inside Portugal, Zhejiang Laysun Magnetics Ltd. provides an integrated system designed to reduce Lead times and lower unit costs.
We bypass third-party trading blocks. By sourcing raw materials directly, we stabilize prices for our European partners, protecting them from market fluctuations.
Our products meet the strict regulatory guidelines of the European Union. We provide full chemical assay disclosures to guarantee safety and compliance at customs checkpoints.
We coordinate seamless transport links directly to your assembly sites in Lisbon, Porto, Setúbal, or Coimbra. We support Sea Freight, Air Cargo, and Express options.
High-performance permanent magnets play a key role in supporting the technological modernization of Portugal's economy. Our products are engineered for specific applications across the country's main industrial sectors:
With the expansion of wind farms off the coast of Portugal, clean-energy generators rely heavily on permanent magnet excitation systems. Sintered NdFeB arc segment magnets provide maximum magnetic flux density within lightweight, compact generator designs, enhancing overall efficiency and reducing long-term maintenance costs.
Portugal's automotive factories require robust supply chains for critical sub-assemblies. Automotive EPS (Electronic Power Steering) systems require high-coercivity NdFeB ring and block magnets that perform reliably under constant vibrations and temperature fluctuations in engine bays.
As industrial facilities in northern Portugal transition toward smart factory standards, high-performance servomotors demand precise rotor assemblies. Our custom neodymium ring and disc magnets deliver high dynamic torque and rapid acceleration profiles for automation systems.
Deep-sea exploration devices, underwater sensors, and automated marine systems operating in the Atlantic demand specialized corrosion protection. Our epoxy and plastic-coated neodymium magnets are designed to withstand seawater environments and prevent galvanic corrosion.
Browse our range of customizable configurations. Our engineers work with your CAD drawings to produce custom dimensions, magnetization vectors, and specialized coatings.
To ensure our NdFeB magnets operate reliably in demanding environments, we maintain strict quality control protocols throughout the entire production cycle.
Raw elements (Neodymium, Iron, Boron, and dysprosium additions) are melted and processed in a vacuum induction furnace to create high-purity alloy structures.
Using advanced wire cutting and inner-circle grinding, we achieve tight dimensional tolerances down to ±0.05mm, satisfying precise mechanical assemblies.
Automated plating lines deposit multi-layered metallic or epoxy barriers to prevent oxidation, tested in salt spray chambers for up to 96 hours.
Hysteresisgraph systems verify remanence (Br), coercivity (Hcj), and maximum energy product (BH max) for every production batch before export.
Find answers to common questions regarding custom neodymium magnets, logistics, and compliance for the Portuguese market.
For custom designs, standard production ranges from 15 to 25 days depending on the complexity of the grade and tooling requirements. Shipping to Portugal via sea freight takes approximately 30-35 days, while air express deliveries arrive at Lisbon or Porto airports within 7-10 business days.
Zhejiang Laysun Magnetics complies fully with REACH regulations and RoHS directives. We provide complete material test reports, chemical composition certifications, and declarations of conformity with every international shipment to ensure smooth customs clearance in Europe.
For coastal or offshore installations exposed to high humidity and salt spray, we recommend Epoxy coating or Parylene treatment. These materials provide superior moisture resistance compared to standard Nickel (NiCuNi) plating, significantly reducing the risk of corrosion-induced demagnetization.
MOQ requirements vary depending on size and grade configuration. For standard dimensions, we support small pilot runs. For highly customized large-scale industrial magnets (e.g., generator rotor arc segments), our sales engineers can discuss custom production options tailored to your project scope.
Yes. Our AH, EH, and UH grades are specifically engineered to withstand elevated operating temperatures up to 200°C. These grades are widely used in automotive drivetrains, traction motors, and aerospace actuators where thermal stability is essential to prevent permanent demagnetization.
