Delivering engineering excellence in rare earth permanent magnet assemblies built for extreme sub-zero operation, heavy abrasive wear, and high magnetic force demands.
Erdenet, home to one of Asia’s largest copper and molybdenum mining and processing complexes (Erdenet Mining Corporation), represents a uniquely demanding industrial environment. Mining machinery, SAG mill liners, high-intensity magnetic separators, and heavy-duty conveyor systems require permanent magnetic assemblies capable of sustaining maximal flux density without thermal demagnetization during freezing winters down to -40°C.
Zhejiang Laysun Magnetics Ltd. acts as a primary engineering partner and exporter to the Erdenet market, supplying customized Neodymium Iron Boron (NdFeB) pot magnets, lifting magnets, magnetic hooks, and heavy industrial magnetic circuits. By integrating advanced Finite Element Method Magnetics (FEMM) with state-of-the-art sintering technology, our magnetic assemblies maximize magnetic field gradients while providing robust anti-corrosive encapsulation.

An architectural insight into why custom magnetic assemblies outperform raw magnets in industrial applications.
A raw magnet emits magnetic fields in all directions. By embedding NdFeB blocks inside low-carbon steel pots or Halbach array configurations, magnetic lines of force are channeled exclusively to the active working surface, increasing pull force by up to 400% compared to unbacked magnets.
Sintered NdFeB material is inherently brittle and prone to micro-fracturing under mechanical collision. Steel, brass, or rubber encasements absorb kinetic shock, ensuring longevity in heavy-duty conveyor belts, mining chutes, and automated assembly lines across Erdenet.
To counter oxidation and chemical breakdown in acidic mining slurry processing, our assemblies undergo multi-layer surface treatment options: Ni-Cu-Ni, Black Epoxy, PTFE (Teflon), Polyurethane, and marine-grade rubber coatings tested to withstand 1000+ hours of Neutral Salt Spray (NSS).

View Product Details & QuotesAnswers to essential technical, logistics, and engineering questions regarding rare earth magnet assemblies.
Raw Neodymium magnets are brittle and distribute magnetic flux in all directions. A magnet assembly combines the magnetic core with low-carbon steel housing or pole pieces. This steel circuit channels and concentrates flux lines onto a single contact surface, increasing pull strength by up to 400%, while the casing protects the fragile ceramic-like magnet core from chipping under structural impacts typical in mining and heavy industrial sites.
Neodymium magnets actually experience an increase in Remanence ($B_r$) and maximum energy product ($BH_{max}$) as temperatures drop. However, severe thermal cycling can cause micro-cracking in low-quality adhesives or coatings. Zhejiang Laysun Magnetics utilizes military-grade structural epoxies and mechanical locking features (such as countersunk rivets and press-fit steel caps) designed to maintain structural integrity across thermal spans from -50°C to +150°C.
Yes. Our engineering team utilizes Finite Element Method Magnetics (FEMM) software to model exact flux density gradients, air-gap performances, and holding forces. We manufacture custom Halbach arrays, magnetic drum separators, magnetic grates, and specialized pot magnet assemblies to meet OEM dimensions and operational requirements.
For corrosive mineral processing or wet screening environments, standard Nickel (Ni-Cu-Ni) is often insufficient. We recommend double-layer Epoxy coating, PTFE (Teflon) encapsulation, or fully sealed 316L Stainless Steel housing assemblies. These coatings pass 1000-hour Salt Spray Tests and resist chemical oxidation from mine water and chemical reagents.
Standard production lead time ranges from 15 to 25 days depending on tooling requirements and coating specifications. Transit time from our China facility to Erdenet via rail/truck through Erenhot / Zamiin-Uud border port usually takes 7 to 12 days. Urgent prototype samples can be dispatched via air freight with magnetic shielding packaging.
