Industrial grade magnet assemblies engineered for local port operations, metallurgy, and ship reclamation sectors.
As the commercial heart of Bangladesh, Chittagong (Chattogram) is undergoing unprecedented industrial growth. Anchored by the busiest port on the Bay of Bengal, the region hosts massive heavy industrial sectors, including major steel mills (such as BSRM, KSRM, and GPH Ispat), massive shipbreaking yards along the Sitakunda coast, and expanding export processing zones (EPZs) focused on textile machinery, light engineering, and high-precision assemblies.
This rapid shift from basic fabrication to high-tech manufacturing demands robust component supply chains. Specifically, heavy-duty magnet lifters, customized permanent pot magnets, and raw sintered neodymium NdFeB blocks are critical in handling raw structural materials, stabilizing massive steel components, and enabling automation inside modern industrial plants. Laysun Magnetics bridges this technological gap by providing world-class, certified magnetic systems engineered to withstand Chittagong's challenging coastal climate.
High humidity and saline air near Chittagong Port accelerate galvanic corrosion in rare earth magnets. Standard plating fails rapidly. Our NdFeB assemblies utilize multi-layered Ni-Cu-Ni + Epoxy or robust Rubber Coating to guarantee longevity and operational safety under coastal industrial environments.
How Zhejiang Laysun Magnetics Ltd. scales advanced automation to meet the rigorous sourcing standards of Chittagong's modern enterprises.
We leverage automated vacuum sintering ovens and precise gas-atomization technology. This ensures perfect grain alignment in the Nd2Fe14B crystal lattice, giving our magnets higher coercivity (Hcj) and energy product (BH-max) ratings.
Adhering to API 6D, API 607, CE, ISO9001, ISO14001, and IATF 16949 standards, we utilize automated optical measurement systems and demagnetization curve plotters to verify batch consistency before shipping to Bangladesh.
With an annual capacity of 5,000 tons, Zhejiang Laysun Magnetics maintains a robust reserve of heavy rare earths (such as Dysprosium and Terbium), mitigating price volatility and securing cost benefits for long-term supply agreements.
Founded at the turn of the millennium in 1999, Zhejiang Laysun Magnetics Ltd. has rapidly evolved from a visionary startup to an industry pacesetter. Our state-of-the-art factory, sprawling across 100,000 square meters in the vibrant industrial zones of China, represents the heart of our operations. Here, our dedicated team of 300 employees works tirelessly to produce an impressive 5,000 tons of rare earth magnets annually.
Specializing in the development, research, production, and sales of high-performance rare earth NdFeB magnets, we cater to a diverse range of global applications. Our magnets are integral to various sectors, including electric vehicles, industrial motors, computers, consumer electronics, and structural lifting gear, enhancing the efficiency and performance of these technologies worldwide.
At Laysun Magnetics, our ethos is built on four pillars - Quality, Credibility, Technology, and Innovation. These values are the cornerstones of our operations, guiding us in delivering products that not only meet but exceed the expectations of our global clients, including those in high-growth markets like Chittagong.
Deploying cutting-edge magnetic engineering across maritime, manufacturing, and metallurgy sectors in Bangladesh.
In Chittagong's massive shipbreaking yards (Sitakunda), safe handling of heavy structural steel plate sections is vital. Our 1000KG magnetic lifters allow operators to lift, orient, and transport heavy iron frames without risky mechanical rigging, vastly improving worker safety and throughput.
Chittagong Port handles more than 3 million TEUs annually. Strong permanent pot magnets and magnetic mounting bases are utilized inside terminal cranes and automated sorting bays to secure sensor arrays, heavy lighting systems, and structural fixtures without drilling or welding.
Inside Chittagong's EPZs, textile manufacturing machinery operates at high speeds. Precision NdFeB block magnets and customized voice coil motor (VCM) magnets are deployed within advanced electronic looms and yarn tensioning sensors to control tension with microsecond accuracy.

High-integrity Rare Earth Neodymium Block, Pot, Hook, and Rubber-Coated Magnets for Chittagong Procurement Managers.
An in-depth whitepaper guide for Chittagong's procurement directors, marine engineers, and heavy industrial plant managers.
Neodymium-Iron-Boron (NdFeB) magnets are dynamic crystalline materials that exhibit highly sensitive responses to local temperature and environmental stress. In typical steel rolling applications in Chittagong mills, high-heat environments are common. Standard neodymium magnets (N-grades) face thermal demagnetization at temperatures exceeding 80°C. To address this risk, Laysun Magnetics offers custom-engineered grades (such as M, H, SH, UH, EH, AH) that utilize dysprosium grain boundary diffusion (GBD) technology. GBD allows our magnets to achieve high coercivity (Hcj) while minimizing rare-earth cost overheads, maintaining stability at working temperatures of up to 230°C.
Because NdFeB consists of a complex multiphase microstructure (specifically, the Nd2Fe14B primary phase surrounded by a highly reactive, neodymium-rich grain boundary phase), exposure to moisture, oxygen, and electrolytes (like saltwater spray in Chittagong’s coastal zones) leads to swift oxidation. This process, often referred to as "magnet crumbling," degrades magnetic flux density. To prevent this, Laysun Magnetics integrates advanced surface treatment lines within our 100,000 square meter factory:
Procuring raw magnetic materials directly from a Chinese high-tech manufacturer significantly lowers project costs and avoids the markups of domestic distributors. Laysun Magnetics coordinates closely with international freight forwarders to manage containerized shipments directly to Chittagong Port (CGP). We ensure all cargo complies with International Air Transport Association (IATA) Packing Instruction 953 and maritime dangerous goods regulations (IMDG code) for magnetized shipments by utilizing steel-shielded outer packaging. This guarantees that magnetic fields are fully contained within the transport boxes, avoiding delays at customs clearance.
