Premium rare-earth magnetic solutions engineered to execute optimal magnetic separation, mechanical drive systems, and electrical conversions.
Established in 1999, Zhejiang Laysun Magnetics Ltd. has evolved into an internationally recognized high-tech manufacturing leader specializing in advanced rare earth permanent magnets and specialized magnetic solutions. With over two decades of engineering heritage, we support critical operations across electric vehicles, heavy industrial machinery, automation, food safety separation, and consumer tech applications.
Operating from our state-of-the-art 100,000 m² manufacturing facility in Suining, Sichuan, and supported by a skilled workforce of 300+ engineering professionals, we generate an impressive annual output of over 5,000 tons of high-grade NdFeB magnets.
Driving industrial standardizations through systematic innovation, deep material sciences, and environmental responsibility.
Magnetic separation is a key physical process used across recycling, food safety, mineral extraction, and chemical production to isolate ferrous contaminants or concentrate valuable magnetic materials. The efficiency of a magnetic separator depends directly on the magnetic field gradient and force index of its internal components.
Zhejiang Laysun Magnetics produces high-performance Neodymium Iron Boron (NdFeB) compounds with remanence (Br) values exceeding 1.45 Tesla (14.5 kGauss) and intrinsic coercivity (Hcj) exceeding 25 kOe. This prevents degradation during prolonged use in harsh environments, such as rotary grate separators, drawer magnets, and magnetic pulleys.
As industrial automation accelerates, the demand for precision magnetic properties grows. For example, voice coil motors (VCM) in optical systems and robotics require uniform flux distribution with low tracking tolerance. In the automotive sector, Electric Power Steering (EPS) systems require tight dimensional tolerances alongside reliable structural integrity under continuous vibration.
Furthermore, in recycling and mining, drum separators utilize high-intensity magnetic circuits to recover valuable metals from waste streams. Our design team uses finite element analysis (FEA) to construct specialized Halbach arrays, which maximize flux concentration on the active face while minimizing weight.
When specifying permanent NdFeB blocks or ring magnets for industrial equipment, engineering departments must evaluate key thermal and environmental variables:
