High-performance NdFeB assemblies designed to withstand rigorous New Zealand marine, material handling, and logistics environments.
Empowering Global Industries with High-Tech Rare Earth Magnetics Since 1999.
Zhejiang Laysun Magnetics Ltd. is a national high-tech leader specializing in the development, research, production, and sales of high-performance rare earth NdFeB magnets and advanced magnetic assemblies. With over two decades of industry leadership, we have grown to become an indispensable partner for complex engineering projects worldwide.
Our operations span a state-of-the-art manufacturing facility covering 100,000 m² in Sichuan, supported by an expert workforce of over 300 professionals. Operating at an annual output capacity of 5,000 tons of rare earth magnets, Laysun Magnetics offers unmatched reliability, scale, and custom design capacities to Kiwi manufacturers, marine engineers, and primary producers across New Zealand.
Understanding the unique macro-environmental and mechanical demands of the southwestern Pacific market.
In New Zealand, the agricultural sector, particularly dairy processing (with global giants like Fonterra), is the economic backbone. For food safety and machinery protection, magnetic separator assemblies are critical. The Ministry for Primary Industries (MPI) enforces strict sanitary standards. Processing milk powder, lactose, and grains requires magnetic bars and grates with magnetic field densities exceeding 10,000 to 12,000 Gauss. Laysun Magnetics customizes premium NdFeB pot and tube magnets encapsulated in 316L stainless steel, meeting CIP (Clean-In-Place) protocols and resisting thermal shock.
With major marine hubs in Auckland and Nelson, Kiwi aquaculture and shipbuilding require magnetic systems capable of operating under continuous exposure to salt water. Traditional NdFeB magnets corrode rapidly in ocean environments. We provide specialized solutions such as EPDM / TPU Rubber-Coated Magnets and advanced multi-layer coatings (Nickel-Copper-Nickel + Epoxy resin or Teflon). These protective layers prevent oxidation, eliminate galvanic corrosion on mounting surfaces, and maintain structural holding power even in severe marine environments.
As New Zealand moves towards its goal of 100% renewable electricity generation by 2030, wind power and hydro-power infrastructure are undergoing significant expansions. Modern direct-drive wind turbines rely heavily on high-coercivity NdFeB arc segment magnets. Laysun Magnetics supplies thermal-stable magnet grades (ranging from SH to EH series) that can withstand temperatures up to 200°C, ensuring the longevity and stability of generators operated by local power utilities.

The standard industrial coating consisting of a copper layer sandwiched between two nickel layers. Ideal for indoor automation, sensors, and clean room packaging in standard dry environments. Offers 24-48 hours salt spray resistance (ASTM B117).
Epoxy offers excellent moisture barrier properties and up to 96 hours of salt spray resistance. Teflon coatings provide low-friction coefficients and chemical inertness, making them suitable for laboratory instrumentation and acid/alkali exposures.
Premium vulcanized rubber completely seals the magnet assembly. The rubber layer increases shear-direction friction, prevents surface scratching, and offers up to 500+ hours of continuous salt spray protection. Engineered for outdoor vehicle mounting and marine rigging.
How New Zealand's core industries utilize Laysun's high-tech magnetic systems daily.
Dairy processing lines must eliminate microscopic metal filings (tramp iron) originating from grain handling mills. Our custom-designed magnetic grates are placed inside bulk receiving hoppers. Utilizing N52-grade rare earth magnets, they capture particles as small as 0.1 mm, preventing machine damage and securing food-grade safety certifications for exported dairy products.
Lifting heavy raw logs and steel components requires extreme lifting forces. Our 1000KG-capacity Neodymium lifters are widely used in South Island sawmills and fabrication yards. A dual-safety factor of 3.5x ensures worker safety, in line with WorkSafe New Zealand Guidelines for Safe Lifting Operations.
Laysun rubber-coated pot magnets are used for mounting instrumentation, sonar devices, and temporary fixtures to hulls without drilling. The high-friction rubber prevents sliding, while the internal Ni-Cu-Ni triple plating combined with watertight rubber molding eliminates ocean saltwater corrosion.
High temperatures inside power plants cause standard magnets to demagnetize. We supply High-Coercivity UH and EH grade NdFeB magnets that maintain magnetic flux at operating temperatures of 150°C to 200°C. This ensures stable power generation and minimizes maintenance downtime.
Headquartered in Hangzhou, China, with manufacturing plants in Sichuan, Laysun Magnetics operates a global distribution network. We provide seamless shipping services directly to New Zealand ports including Auckland, Tauranga, and Lyttelton (Christchurch).
Quality Certifications: API 6D, API 607, CE, ISO9001, ISO14001, ISO18001, TS16949.

Pioneering green energy efficiency and next-generation heavy-duty magnetics.
As international demands for environmental sustainability rise, Laysun Magnetics is focusing on "Green Rare Earth Recycling" protocols. Our research team is developing methods to reclaim Neodymium magnets from end-of-life wind turbines and electric vehicles, reducing carbon footprints by up to 60%. This initiative aligns with New Zealand’s Zero Carbon Act 2019, positioning Laysun as a sustainable supply chain partner for green-conscious Kiwi enterprises.
Furthermore, our technological roadmap includes the development of Grain Boundary Diffusion (GBD) technology. This method allows us to manufacture magnets with exceptionally high coercivity while reducing dysprosium (Dy) and terbium (Tb) usage. The result is lightweight, high-temperature magnetic assemblies that offer lower production costs and improved pricing stability for international buyers.
