Engineered for high thermal stability, complex multi-pole magnetization, and superior environmental resilience across industrial sectors.
Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has evolved from a visionary magnetic materials pioneer to a globally recognized national high-tech enterprise. Our core manufacturing capabilities focus on high-performance sintered and bonded NdFeB (Neodymium Iron Boron) rare earth magnets.
Strategically situated in Hangzhou, China, with a massive 100,000 square meter production facility based in Suining, Sichuan, we maintain strict vertical integration over the entire production life cycle. Our facility is equipped with automated raw material mixing, compression molding, injection molding, precise multi-pole magnetization, and automated visual inspection systems. This extensive infrastructure allows us to guarantee consistency, competitive pricing, and rapid delivery parameters globally.
As micro-electronics, robotic actuators, and electric powertrains continue to demand smaller, lighter, and more complex magnet shapes, Bonded NdFeB has emerged as the premier choice. Unlike sintered magnets, which are highly brittle and require extensive machining, bonded magnets are created by dispersing NdFeB alloy powder within a polymer matrix (such as epoxy or nylon). This permits the direct fabrication of complex geometries with high dimensional accuracy, minimizing secondary finishing costs.
Kiribati, a Pacific nation consisting of 32 atolls and one raised coral island, is at the forefront of the global energy transition. To establish resilient infrastructure, the country is actively modernizing its domestic power grids, desalinization plants, maritime outboards, and smart utility meters. High-precision permanent magnets serve as the critical underlying architecture enabling this modern hardware.
Traditional sintered magnets often degrade rapidly under Kiribati's coastal atmospheric conditions—highly saturated with saline humidity and salt-spray. Zhejiang Laysun Magnetics Ltd. addresses this unique regional challenge by providing custom-formulated Bonded NdFeB magnets. By embedding high-purity NdFeB powder in chemically inert polymer matrices and layering them with advanced dual-layer epoxy and parylene coatings, our products deliver exceptional longevity in hyper-saline oceanic environments.
Additionally, Kiribati's remote location presents distinct supply chain challenges. High transport costs and extended transit times demand highly reliable products with zero defect rates. Through rigorous process control, we ensure our magnets prevent mechanical degradation, thereby minimizing operational downtime in solar water pumps, micro-wind turbines, and deep-sea monitoring arrays across the Gilbert, Line, and Phoenix Islands.
Why engineering leads choose Zhejiang Laysun Magnetics Ltd. for custom bonded NdFeB production and South Pacific shipping.
We apply electro-epoxy coatings, parylene films, and chemical vapor deposition finishes to protect bonded magnets from salt spray, humidity, and tropical heat.
Equipped with advanced magnetization fixtures, we supply rings with radial, axial, multi-pole skewed, and custom magnetic patterns for high-precision motors.
Our isotropic bonded NdFeB compounds enable magnetic properties to remain uniform in all directions, permitting complex shape styling without magnetic loss.
Our processes are fully compliant with ISO 9001, ISO 14001, CE, and API standards, ensuring traceability and consistency for international tenders.
We leverage internal engineering resources to design compression and injection molds rapidly, decreasing prototyping turnaround times to less than 15 days.
We utilize specialized vacuum, shock-absorbent packaging and ocean freight routing through South Pacific hubs (Fiji/Tarawa) to secure critical deliveries.
Bonded NdFeB magnets serve a variety of functions across diverse technical sectors, optimizing space constraints and increasing output efficiency:
Our engineering team works closely with global designers to optimize material selection, balancing magnetic strength (remanence, coercivity, and energy product) with polymer stability. This ensures magnets perform reliably under thermal stress up to 150°C.
Our credentials reflect our commitment to performance, environmental sustainability, and rigorous industrial quality management.

Exporting complex magnetic materials to the South Pacific requires meticulous handling, correct classification, and robust logistics systems. At Zhejiang Laysun Magnetics Ltd., we manage all compliance steps to deliver your orders securely, avoiding delays at ports of entry.
All air and ocean shipments are packed using magnetic shielding materials, keeping external magnetic fields below 0.00525 gauss to comply with IATA packing instructions. This makes our shipments safe for standard air carriage.
For ocean shipments arriving in Tarawa, we package our products in vacuum-sealed plastic bags containing high-grade desiccants. They are then placed inside heavy-duty, reinforced wooden crates lined with moisture-proof layers to prevent oxidation during transit through hot, humid maritime regions.
