As Latin America’s largest economy, Brazil is currently undergoing a profound industrial transformation. Driven by the federal government's *Nova Indústria Brasil* (New Industry Brazil - NIB) initiative, the country is prioritizing local manufacturing, digitization, decarbonization, and ecological transition. Central to this strategic push is the deployment of high-efficiency electric motors, intelligent sensors, and automated industrial hardware—all of which rely fundamentally on advanced rare earth permanent magnet technologies.
Bonded Neodymium Iron Boron (NdFeB) magnets play a critical role in this modern landscape. Unlike their sintered counterparts, bonded NdFeB magnets are manufactured by blending isotropic NdFeB magnetic powder with thermosetting epoxy resins or thermoplastic polymers. This compounding technique allows for the production of highly complex, thin-walled shapes through injection molding, compression molding, or extrusion—completely eliminating the need for expensive secondary machining processes.
From the high-tech automotive hubs in São Paulo and Paraná to the Manaus Free Trade Zone (Zona Franca de Manaus) electronic assembly clusters, the demand for precision magnetic components has surged. The rapid growth of Brazil's flex-fuel and hybrid electric vehicle (HEV) programs, combined with regional investments in industrial robotics and localized agrotech systems, requires a reliable, high-volume supplier of rare earth products. Laysun Magnetics bridges this technological gap by providing world-class manufacturing capabilities aligned with local regulatory frameworks and Brazilian supply chain demands.
A trusted global manufacturer of advanced rare earth permanent magnetic solutions, empowering industries with technological innovation and scaled production capacity.
Founded at the turn of the millennium, Zhejiang Laysun Magnetics Ltd. has rapidly evolved from a visionary developer to a national high-tech manufacturing leader. Headquartered in the historic industrial corridor of Zhejiang, and operating a flagship 100,000 square meter production facility in Suining, Sichuan, we focus on the research, synthesis, coating, and magnetization of high-performance rare earth NdFeB products. With an annual capacity of 5,000 tons of rare earth magnetic materials, we guarantee uninterrupted volume deliveries, competitive pricing, and rigorous quality standards for global enterprises sourcing for the Brazilian and broader South American markets.
Our systems comply with IATF 16949 (automotive grade standard), ISO9001, ISO14001, and ISO45001, ensuring compliance with strict domestic and international protocols.
Leveraging China's dominant rare earth raw material supply chains allows us to shield our Brazilian clients from global price volatility and material shortages.
Our dedicated engineering department continually works on custom compound formulations, advanced corrosion protection coatings, and complex multi-pole ring designs.
Navigating the customs processes and import duties in Brazil (known as the *Custo Brasil*) requires partnering with a manufacturer that offers absolute transparency, reliable logistics, and strict quality control. Zhejiang Laysun Magnetics Ltd. provides customized business models specifically tailored to handle shipment structures to major Brazilian ports, including Santos, Paranaguá, and Rio Grande.
As rare earth extraction and refining are concentrated heavily in China, sourcing your bonded NdFeB magnets directly from a China-based national high-tech enterprise like Laysun provides a fundamental competitive edge. We manage our supply lines directly from state-owned extraction plants, guaranteeing that our raw powder materials (Nd, Dy, Fe, B, and proprietary dopants) are ethically sourced, conflict-free, and highly consistent from batch to batch.
Much of Brazil's manufacturing is subjected to coastal climates characterized by high ambient humidity and heat—especially in industrial hubs like Manaus, Bahia, and Rio de Janeiro. Standard unprotected NdFeB magnets are highly susceptible to oxidation. To address this environmental challenge, Laysun utilizes high-durability electrocoat epoxy (E-coat) technologies, Parylene deposition, and multi-layer chemical plating configurations designed to exceed 500 hours of continuous salt spray testing (SST).
From complex automotive subsystems to household convenience and industrial green energy initiatives, we optimize efficiency.
Brazilian automotive plants rely on bonded NdFeB rings for Electric Power Steering (EPS) motors. These systems require radial multi-pole configurations, offering smooth tactile feedback, reduced fuel consumption, and consistent torque transfer.
As the Brazilian government implements strict energy labels (Procel labels) for air conditioners, refrigerators, and washing machines, our magnets help local appliance manufacturers shift toward inverter-driven brushless DC (BLDC) compressors.
We supply precision cylindrical and ring magnets for industrial robotic encoders, fluid meters, and agricultural sensor devices, maintaining structural performance under heavy vibration, dust, and temperature variations.

| Property Parameter | Bonded NdFeB Magnets | Sintered NdFeB Magnets | Engineering Implications for Brazil |
|---|---|---|---|
| Maximum Energy Product (BH max) | 5 - 12 MGOe | 30 - 55 MGOe | Sintered offers maximum magnetic force; Bonded excels in precise flux control. |
| Dimensional Tolerance | ±0.02mm to ±0.05mm (no grinding) | ±0.05mm to ±0.1mm (requires grinding) | Bonded allows direct integration without costly post-machining phases. |
| Shape Complexity | Extremely high (thin walls, custom gears, overmolding) | Basic geometries (blocks, arcs, simple discs) | Bonded is highly suited for complex multi-pole stator/rotor combinations. |
| Magnetization Configuration | Isotropic (magnetize in any direction, multi-pole radial) | Anisotropic (fixed orientation direction during pressing) | Bonded allows multi-pole rings to be oriented uniformly in one solid part. |
| Corrosion Resistance | High (epoxy resin binder protects powder particles) | Moderate to Low (highly prone to oxidation, needs coating) | Bonded performs exceptionally well in hot, high-humidity coastal regions. |
