MATERIAL PREPARATION
& ALLOYING
Mastering the raw foundation for extreme magnetic performance.
1
Strip Casting (SC)
Vacuum induction melting eliminates alloy segregation, producing a uniformly fine microstructure at the molecular level — the foundation for consistent magnetic performance.
2
Hydrogen Decrepitation (HD)
Controlled hydrogen absorption fractures cast alloy into coarse, high-purity powder particles with minimal contamination and preserved grain structure.
3
Jet Milling
High-pressure nitrogen pulverization achieves precise 3–5 μm particle size distribution — the critical range for maximizing intrinsic coercivity in sintered NdFeB.
MAGNETIC ALIGNMENT & SINTERING
Locking in the magnetic direction and achieving peak theoretical density.
4
Magnetic Field Pressing
Powder particles are aligned under a powerful applied magnetic field, maximizing crystallographic orientation and directly determining the magnet’s remanence (Br) ceiling.
5
Cold Isostatic Pressing (CIP)
Uniform hydraulic pressure from all directions eliminates internal density gradients, producing a green body with ultra-high uniformity and minimal cracking risk.
6
High-Vacuum Sintering & Aging
Precisely programmed thermal cycles in full vacuum achieve final metallurgical bonding, establishing both core density (>7.55 g/cm³) and the initial coercivity baseline.
PRECISION MACHINING
& GBD TECHNOLOGY
Where tolerances are measured in microns and performance is engineered, not assumed.
7
Precision Machining
Multi-wire cutting and CNC surface grinding achieve dimensional tolerances as tight as ±0.01mm across any custom geometry — blocks, arcs, rings, and complex segments.
8
★ CORE TECHNOLOGY
Grain Boundary Diffusion (GBD)
Heavy rare-earth elements (Tb/Dy) are diffused directly into the magnet’s grain boundaries under precise vacuum-thermal conditions — surgically boosting Intrinsic Coercivity (Hcj) by up to 30% with zero sacrifice in remanence.
Surface Coating & Quality Assurance
Defying corrosion and guaranteeing zero-defect delivery to every global destination.
