Explore our primary high-grade NdFeB magnet solutions designed to meet the strict quality standards of the Eastern Economic Corridor (EEC) of Thailand.
Thailand has rapidly positioned itself as the "Detroit of Asia," serving as a strategic powerhouse for automotive manufacturing and consumer electronics assembly in Southeast Asia. The Eastern Economic Corridor (EEC) initiatives have accelerated the development of smart electronics, electrical appliances, robotics, and next-generation vehicles. Inside these technologies lies a crucial component: Bonded NdFeB (Neodymium Iron Boron) Magnets.
Unlike sintered magnets, bonded NdFeB is manufactured by mixing rapid-quenched NdFeB magnetic powder with polymer binders (such as epoxy or nylon) through compression or injection molding. This delivers exceptional dimensional accuracy, enabling the production of highly complex shapes (such as thin-walled rings, radial multipolar configurations, and integrated rotor assemblies) without complex mechanical machining. For Thai industrial giants, this translates to minimal waste, lower unit cost, and maximum efficiency in precision micro-motors and sensor applications.
Understanding the performance matrices of Bonded NdFeB and Sintered NdFeB to make an informed procurement decision for your Thailand engineering projects.
| Magnetic / Physical Property | Bonded NdFeB (Compression/Injection) | Sintered NdFeB | Engineering Value for Thai OEMs |
|---|---|---|---|
| Maximum Energy Product (BHmax) | 5.0 – 12.0 MGOe | 30 – 55 MGOe | Bonded is optimized for complex micro-sensors, while sintered suits high-torque heavy traction motors. |
| Dimensional Tolerance | ±0.02mm (Net Shape, no machining) | ±0.10mm (Requires grinding/wire cutting) | Perfect for hard disk drives (HDD) and precision automotive steering sensors in Chonburi factories. |
| Magnetization Profiles | Isotropic (Any direction, multi-pole radial) | Anisotropic (Oriented direction, limited profiles) | Enables multi-pole skew magnetization to minimize cogging torque in EPS motors. |
| Corrosion Resistance | High (Polymer matrix protects against humidity) | Low (Highly prone to oxidation, needs thick coating) | Resists Thailand's tropical high-humidity environments. Additional epoxy or Parylene coating adds durability. |
| Density (g/cm³) | 6.0 – 6.5 | 7.4 – 7.6 | Reduces overall weight in aerospace components, drone rotors, and portable medical electronics. |
Our isotropic bonded NdFeB powders allow for flexible magnetization profiles after molding, simplifying your motor assembly logistics.
Equipped with high-performance heat-resistant polymer matrices that withstand operating temperatures up to 180°C in continuous operation.
From custom tooling and magnetic simulation (FEA) to multi-pole ring designs with specific skew angles, we execute to exact prints.
How our custom-tailored rare earth magnets support regional manufacturers across the key industrial zones in Thailand.
Thailand is aggressively driving the EV 3.0/3.5 policy, drawing battery EV investments from top-tier global automakers into Chonburi and Rayong provinces. Our customized NdFeB magnets, particularly the block sintered magnets and high-pole bonded rotors, are heavily integrated into Electronic Power Steering (EPS), thermal management pumps, and auxiliary motors. High thermal stability prevents demagnetization during long drives under high engine cabin temperatures.
As a global hub for air conditioner compressors and high-end refrigerator manufacturing, Thai household appliance brands demand highly efficient brushless DC (BLDC) motors. Our compression-molded NdFeB ring magnets enable higher energy efficiency ratings (COP) with quiet operation. They offer precise motor control, reduced noise levels, and lower structural vibration for washing machines and home HVAC units.
Thailand’s high relative humidity and warm coastal air introduce severe oxidation risks. Plain NdFeB magnets can degrade rapidly if left unprotected. We supply optimized anti-corrosion treatments including advanced black/grey epoxy coatings (tested beyond 1000 hours in salt spray testing), Parylene passivation, and high-quality nickel-copper-nickel electroplating to ensure long-term physical and magnetic integrity.
Through the ASEAN-China Free Trade Area agreements, our Thailand customers benefit from reduced import tariffs by leveraging Form E certificates. This ensures seamless custom clearance and maximum cost efficiency. Additionally, our materials are fully RoHS, REACH, and Conflict Minerals compliant, matching the regulatory standard required for export-oriented products bound for Europe and North America.

Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has grown to become a national high-tech leader in manufacturing rare earth magnets. Our main factory covers 100,000 square meters in Suining, Sichuan, supporting a dedicated workforce of over 300 employees and an impressive annual output capacity of 5,000 tons of high-grade rare earth NdFeB magnets.
We operate fully automated powder preparation systems, advanced high-tonnage compression presses, multi-axis injection molding stations, and continuous vacuum sintering ovens. This deep production capability enables us to serve high-volume orders for regional manufacturing clusters in Thailand (including Chonburi, Rayong, Ayutthaya, and Samut Prakan) while maintaining strict batch-to-batch consistency.
Zhejiang Laysun NdFeB magnets power key technologies in modern high-precision markets.
We maintain a rigorous quality assurance loop matching ISO9001 and high automotive standards for demanding industrial applications.
Our manufacturing processes comply with API 6D, API 607, CE, ISO9001, ISO14001, ISO18001 and the IATF 16949 technical specification for automotive components. If your internal compliance team requires original verification documents, testing reports, or chemical composition curves, please contact our engineering support desk.
How Laysun Magnetics addresses evolving global demand and technological innovations in the magnetic materials sector.
To counter the rising cost and geopolitical volatility associated with heavy rare earth elements like Dysprosium (Dy) and Terbium (Tb), Laysun is developing Grain Boundary Diffusion (GBD) technologies and Dy-free bonded powder mixtures. This approach ensures excellent high-temperature stability without adding cost.
We are developing injection-molded hybrid magnets containing both NdFeB and ferrite powders. By adjusting the blend ratio, we can tailor the magnetic properties to fit specific engineering performance requirements.
