Explore our core selection of heavy-duty neodymium assemblies engineered to handle demanding industrial, logistics, and marine recovery applications in the Bangkok metropolitan area.
Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has evolved from an ambitious high-tech startup into an internationally recognized pacesetter in rare earth magnet manufacturing. Spanning over 100,000 square meters of state-of-the-art production facilities in Suining, Sichuan, our manufacturing plants utilize automated vacuum induction melting furnaces, inert-gas jet mills, and fully automated multi-stage hydraulic presses. Our dedicated team of 300+ professionals engineering-focused operators ensures an annual capacity of 5,000 tons of high-grade sintered Neodymium Iron Boron (NdFeB) material.
Our global distribution networks serve advanced engineering projects across North America, the European Union, East Asia, and the rapidly growing manufacturing hubs of Southeast Asia. We support precision electric vehicle (EV) drivetrains, robotics, wind energy systems, sensor assemblies, and custom pot magnets. Every product leaving our cleanroom facilities undergoes rigorous testing via computer-aided hysteresisgraphs, salt-spray chambers, and optical coordinate measuring machines, certifying that our systems offer superior magnetic flux density and stability.
The Greater Bangkok Area, spanning Pathum Thani, Samut Prakan, and the neighboring Eastern Economic Corridor (EEC) zones of Chonburi and Rayong, represents the manufacturing powerhouse of Southeast Asia. Often referred to as the "Detroit of the East," the region hosts massive automotive assembly lines, electronics manufacturing service (EMS) giants, and food processing complexes. This concentration of precision manufacturing has driven a steep increase in demand for highly reliable magnetic separation grids, automated robotic magnetic grippers, electric vehicle motor rotors, and sensor assemblies.
Unlike simple raw magnet blocks, industrial applications in Bangkok require custom magnetic assemblies—where magnets are integrated with steel cups, threaded housings, rubber pads, or aluminum structures. This hybrid design channels the magnetic flux lines into a concentrated path, dramatically increasing the holding force. Industrial sectors in Bangkok operate under challenging environments characterized by high humidity, elevated operating temperatures, and exposure to corrosive substances. Consequently, standard plating is insufficient. Companies operating in the Bang Na or Laem Chabang industrial zones require advanced coating methods, such as marine-grade rubber molding, double-layer nickel-copper-nickel (Ni-Cu-Ni), epoxy resin, or Teflon (PTFE) protection to guarantee service life and avoid magnetic decay.
Supporting OEMs in Samut Prakan and Rayong with custom sintered NdFeB arc segment magnets for steering systems (EPS), direct-drive electric powertrains, and high-temperature performance rotors (grades up to 52SH, UH, EH).
High-precision voice coil motor (VCM) assemblies and magnetic rings for high-density consumer electronics assembly lines located throughout Pathum Thani's science parks.
Ensuring compliance with local FDA standards using sanitary-grade magnetic tube separators, grates, and drawer assemblies to remove ferrous contaminants from rice and sugar processing lines.
The pricing of rare earth neodymium magnets and assemblies in Bangkok is governed by global commodity indexes for Neodymium (Nd), Praseodymium (Pr), Dysprosium (Dy), and Terbium (Tb). Because China produces the vast majority of the world's rare earth raw materials, pricing trends in Bangkok directly correlate with the China Rare Earth Price Index. However, local transaction prices in Thailand also incorporate import tariffs, localized ocean or air freight logistics, customs clearance fees, and technical certification expenses.
To help purchasing managers, engineering teams, and supply chain directors forecast project costs, we maintain a clear pricing roadmap based on raw material purity and assembly complexity. The table below represents estimated baseline prices for key magnetic assemblies in the Bangkok market, depending on batch volumes, material grades, and specialized coatings:
| Magnetic Assembly Class | Common Grade Range | Standard Coating | Price Bracket (Large Batch / FOB) | Primary Industrial Use Case in Bangkok |
|---|---|---|---|---|
| NdFeB Pot Magnets (Style A/B/C) | N35 to N52 | Ni-Cu-Ni / Zinc | $0.45 - $3.80 / pc | Retail displays, shop fittings, light industrial fixtures |
| Rubber Coated Assemblies | N38 to N45 | Synthetic Rubber (TPE) | $1.20 - $8.50 / pc | Outdoor signage, automotive mounts, marine environments |
| Heavy Duty Lifter (1000KG) | N40SH / N42H | Powder Coated Steel | $180.00 - $350.00 / unit | Metal fabrication, shipyard steel plate moving, warehouse rigging |
| Custom Arc Rotor Segments | 38SH to 48UH | Epoxy / Passivated | Based on Blueprint Specs | High-temperature industrial motors, wind energy, EV drivetrains |
| VCM Magnetic Assemblies | N50H to N52SH | Nickel / Gold Plating | $0.80 - $4.20 / pc | Consumer electronics, optical disk drives, precision actuators |
In response to global demands for sustainable sourcing and cost stabilization, Zhejiang Laysun Magnetics Ltd. is continuously refining its technical roadmap. High-temperature neodymium magnets historically relied on heavy rare earth elements (HREEs) like Dysprosium (Dy) and Terbium (Tb) to maintain their magnetic properties at temperatures exceeding 120°C. By deploying advanced Grain Boundary Diffusion (GBD) technology, our R&D division has successfully reduced HREE usage by up to 70% while achieving thermal thresholds up to 240°C (EH grades).
This breakthrough significantly lowers raw material costs, insulating our Bangkok clients from price spikes in the raw rare earth market. Additionally, for food safety and medical manufacturing, we have developed zero-lead, food-grade passivated epoxy coatings and SUS316 stainless steel welded encapsulation systems. These ensure that no magnetic material can migrate into products during extreme clean-in-place (CIP) washdowns.
To meet the strict environmental and trade compliance standards of Thailand, our manufacturing facilities adhere to strict global frameworks.

A raw neodymium magnet has open flux lines that radiate in all directions. A magnetic assembly, such as a pot magnet, houses the magnet within a steel cup. This ferromagnetic cup redirects the magnetic flux back to the contact surface, doubling or tripling the direct holding force compared to a raw magnet of the same size. Additionally, the steel housing protects the fragile NdFeB material from mechanical impacts, extending its lifespan.
Sintered NdFeB contains iron, which makes it highly susceptible to rust in high-humidity tropical environments like Bangkok. To prevent oxidation, we offer multilayer electroplating (Ni-Cu-Ni or copper+epoxy) and hermetically sealed stainless steel (SUS304 or SUS316) housings. For outdoor or marine applications, rubber-molded (TPE) magnet assemblies provide an airtight barrier against moisture and saline exposure.
Standard NdFeB (N-grade) begins to experience demagnetization at 80°C. For industrial and automotive motor applications in Thailand, we recommend using H-grade (up to 120°C), SH-grade (up to 150°C), UH-grade (up to 180°C), or EH-grade (up to 200°C) materials. This ensures that the magnets retain their magnetic properties under continuous thermal stress.
