Order Bulk BadgesAs Nigeria pivots towards intensive economic diversification, the nation is witnessing an unprecedented leap in manufacturing, localized automotive assembly, renewable energy generation, and smart grid automation. In cities like Lagos, Port Harcourt, and Kaduna, local production lines are shifting from low-tech manufacturing to highly sophisticated mechanical assemblies. This industrial shift necessitates raw materials and custom-engineered parts that meet strict global specifications.
Bonded NdFeB (Neodymium-Iron-Boron) magnets have become the cornerstone of modern industrial growth. Unlike traditional sintered magnets, bonded NdFeB offers unmatched dimensional flexibility, allowing for thin-walled rings, intricate geometric profiles, and multi-pole radial configurations without the need for secondary tooling or costly machining.
For Nigerian engineering firms, importing premium bonded NdFeB from an experienced Chinese manufacturer guarantees access to consistent magnetic flux, high structural reliability, and cost-effective design options. Whether you are assembling smart prepaid water/electricity meters, setting up solar energy microgrid components, or sourcing components for consumer appliance assembly, Zhejiang Laysun Magnetics Ltd. provides the critical expertise to empower your enterprise.
How our custom-tailored bonded magnets are used across West Africa's leading industries to drive efficiency, reliability, and precision.
Under the Meter Asset Provider (MAP) framework, Nigeria requires robust, tamper-resistant prepaid electricity and water meters. Our multi-pole bonded NdFeB ring magnets offer high magnetic stability, preventing external tampering and ensuring precise calibration over years of operation.
As domestic vehicle assembly plants expand in Lagos and Enugu, high-performance Electric Power Steering (EPS) motors are required. Our isotropic NdFeB rings with epoxy coating provide high mechanical toughness, preventing motor failure in humid and harsh sub-Saharan terrains.
Offshore installations in Port Harcourt rely on electronic flow meters and level indicators. Our custom rubber-coated and nickel-plated neodymium magnets resist saline environments and corrosive gases, keeping instrumentation precise.
Your Trusted Partner in Advanced Rare Earth Magnetic Technology Since 1999
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has evolved from a visionary magnetics manufacturer into a recognized Chinese National High-Tech Enterprise. With a sprawling, modern production facility spanning 100,000 square meters in Sichuan and headquarters in Hangzhou, our workforce of over 300 experts focuses on the research, production, coating, and testing of rare earth permanent magnets.
We maintain an annual production capacity exceeding 5,000 tons of permanent rare earth magnets. Our solutions serve vital international markets, supplying clean energy projects, aerospace systems, advanced robotics, medical equipment, and consumer electronics. Our products undergo rigorous quality testing, including magnetic flux testing, mechanical tolerance verification, and corrosion testing (HAST/SST), to ensure peak performance in all operating conditions.
Providing Nigerian enterprises with direct factory-pricing, high-grade rare earth material supply, and custom logistics solutions.
Sourcing bonded NdFeB requires extreme quality control. Our materials utilize high-purity Neodymium (Nd), Iron (Fe), and Boron (B) alloys blended with advanced epoxy resins or polyamide binders. Our automated compaction molding and injection molding machines process these materials under controlled temperatures, achieving density levels between 6.0 and 6.5 g/cm³.
This high-precision method produces isotropic bonded magnets that can be magnetized in a variety of complex configurations (axial, radial, multi-pole skew, etc.) after molding. This offers critical design freedom for domestic product designers and engineers looking to build compact electric motors, oil filters, or acoustic diaphragms.
We understand the challenges of custom clearance, tariff regulations, and transit times for shipments to Lagos (Apapa/Tin Can Island) or Port Harcourt ports. We package our magnetic products with complete magnetic shielding protection (soft iron plating and heavy-duty wooden crates) to comply with international air cargo regulations (IATA) and sea shipping rules, preventing any delay or interference with commercial shipping systems.
Every shipment of bonded magnets complies with rigorous international frameworks, guaranteeing performance stability in harsh West African operations.

Detailed answers to common questions about bonded NdFeB design, coating options, logistics, and magnetic properties.
Bonded NdFeB magnets are manufactured by blending isotropic NdFeB magnetic powder with plastic binders (such as epoxy, nylon, or PPS) and then forming them via compression molding or injection molding. This process allows for extremely complex shapes, thin walls, and precise tolerances (often within ±0.02 mm) straight out of the mold, removing the need for grinding. Sintered NdFeB magnets are made by pressing alloy powder and then heating it in a sintering furnace. While sintered magnets offer higher magnetic strength (maximum energy product BH max), they are fragile, limited in shape complexity, and require expensive diamond grinding to achieve precise tolerances.
Neodymium magnets contain iron, making them prone to oxidation in high-humidity areas. To prevent this, we apply protective coatings. For bonded NdFeB, we offer epoxy coatings applied via electrophoresis, which seal the magnet completely. For sintered NdFeB, we offer multi-layer nickel-copper-nickel (Ni-Cu-Ni), zinc (Zn), or organic epoxy coatings. For extreme coastal conditions, we recommend custom rubber-coated or plastic-injected enclosures to prevent moisture penetration.
The maximum operating temperature of bonded NdFeB depends on the type of binder resin used. Standard epoxy-bonded magnets operate reliably at temperatures up to 120°C. For high-temperature applications, such as automotive under-hood components or heavy-duty industrial electric motors, we use polyamide or PPS binders combined with high-coercivity NdFeB powders. This increases the thermal limit to 150°C or even 180°C, preventing thermal demagnetization.
Yes. Since bonded NdFeB utilizes isotropic powder, the magnetic particles are oriented randomly. This allows us to magnetize the finished piece in any direction. We design and build custom magnetization fixtures in-house to produce complex profiles. This includes multi-pole radial, axial skew, or custom planar magnetization patterns, which are ideal for high-precision rotating encoders, brushless DC (BLDC) motors, and smart meters.
For custom-dimension bonded magnets, tool design and prototyping take 10 to 15 business days. Once approved, mass production takes 15 to 25 days depending on the volume. Shipping is available via ocean freight directly to Lagos ports (Apapa/Tin Can Island) with a transit time of 30 to 40 days, or via air cargo to Lagos International Airport (Murtala Muhammed) for urgent delivery within 7 to 10 days, utilizing full magnetic shielding packaging.
