Contact Exporter →Modern industry demands efficiency, precision, and raw structural reliability. As clean energy sectors expand, the integration of high-coercivity rare earth magnets becomes crucial. Permanent magnetic materials (predominantly Sintered Neodymium-Iron-Boron (NdFeB)) represent the core of structural motion and industrial automation. At the same time, the civil infrastructure industry is undergoing a structural transition toward modular precast concrete assemblies.
Utilizing high-performance magnetic fixing solutions allows precast concrete plants to phase out traditional, destructive welding and bolting methods. Our specialized shuttering systems allow operators to lock down formwork securely onto casting tables, drastically lowering labor cycle times while extending the service life of expensive steel machinery.
“By optimizing the magnetic circuit of sintered NdFeB blocks inside protective steel casing, we achieve up to 2500 kg of holding force in a box weight of just several kilograms—establishing a new standard in shear resistance and durability.”
Coercivity ($H_{cj}$): ≥ 12 kOe to prevent demagnetization at higher temperatures.
Remanence ($B_r$): Up to 1.45 Tesla for high flux density output.
Shear Protection: Patented spring-loaded release structures that safeguard worker safety and optimize cycle times.
We leverage magnetic field simulation software to calculate maximum flux concentration. Each magnet box utilizes optimized flux paths, resulting in maximum clamping efficiency.
Featuring dual-layer zinc-nickel and epoxy surface protections. Tested to withstand up to 72 hours of direct salt spray testing under extreme building environment conditions.
Every industrial production batch undergoes strict hysteresis testing. We ensure zero performance loss over years of repeated mechanical activation on structural steel beds.
Engineered for heavy precast structures, our core range ensures unmatched stability, dynamic locking, and long term mechanical reliability.
Optimized for rapid positioning. Provides clean edges for precast concrete plates.

Understanding Sintered NdFeB Crystalline Structures: Sintered Neodymium magnets consist of an intermetallic tetragonal phase ($Nd_2Fe_{14}B$) showing exceptional uniaxial magnetocrystalline anisotropy, allowing them to resist demagnetization over decades of service.
Our research focuses on Grain Boundary Diffusion (GBD) technology. GBD allows us to introduce Dysprosium (Dy) or Terbium (Tb) selectively into the boundary region of NdFeB crystals rather than distributing them throughout the entire alloy. This dramatically boosts intrinsic coercivity ($H_{cj}$) while avoiding the drop in remanence ($B_r$) that occurs with traditional alloying methods. Consequently, our magnets operate at higher temperatures without sacrificing magnetic strength.
Another major technological focus is anti-corrosion protection. Precast concrete environments present challenges with high humidity, alkaline concrete chemistry, and mechanical abrasion. Our multi-stage passivation coating procedures ensure that moisture and oxygen cannot penetrate the micro-porosities of the sintered rare earth matrix, maintaining consistent holding force and performance.
