Each machine is calibrated regularly and monitored via IoT-enabled sensors to ensure optimal performance and consistency. For instance, our vacuum hydrogen crushing furnace operates under precise pressure and temperature control (700–1000℃), enabling efficient hydrogen decrepitation of raw NdFeB alloy into fine powder—a critical step for achieving uniform grain structure. The jet mill then reduces particle size to sub-micron levels, enhancing magnetic alignment during pressing. Our magnetic field forming press applies up to 25 kOe of aligning field strength, ensuring maximum orientation of magnetic domains. After sintering in the vacuum furnace, parts proceed to CNC machining with ±0.01mm tolerance, followed by surface treatments like electroless nickel plating or Parylene coating—each applied under controlled environmental conditions. A standout feature is our dual magnetizing system: magnets are charged twice—first in a pulsed field, then in a DC field—to achieve full saturation and eliminate residual demagnetization. This two-step process is especially vital for high-coercivity grades like N55H and N52UH, which are used in aerospace and defense applications. Furthermore, our continuous sintering furnace allows for uninterrupted production flow, increasing throughput by 30% compared to batch systems.

• Grain Boundary Diffusion (GBD) Technology:
IT-MAG is at the forefront of rare-earth magnet innovation through its proprietary Grain Boundary Diffusion (GBD) technology—an advanced process that significantly enhances the coercivity of NdFeB magnets without compromising their magnetic strength. Unlike traditional methods that rely on increasing heavy rare earth content (Tb/Dy), GBD selectively diffuses these elements into the grain boundaries of sintered magnets, creating a more stable microstructure. This breakthrough allows us to produce high-grade magnets such as N55H and N52UH—previously unattainable with conventional techniques—while reducing Tb/Dy usage by up to 40%. The process begins with pre-treatment to remove oil and scale, followed by coating Dy/Tb onto the magnet surface. The coated magnets are then heated in a vacuum furnace at 700–1000℃, enabling controlled diffusion deep into the grain boundaries. After milling and surface treatment, the final product exhibits intrinsic coercive forces ranging from 12 to 40 KOe, depending on grade. For example, N54H magnets treated with GBD show a 25% increase in thermal stability at 150℃ compared to untreated counterparts. In real-world testing, these magnets maintained 92% of their magnetic flux after 100 hours at 150℃—a critical advantage for electric vehicle motors and industrial drives. Our R&D team has validated this technology across over 100 different magnet grades, including N45, N48, and N50, proving its versatility. Clients in the automotive sector, including those supplying Ferrari and FIAT, have adopted our GBD-enhanced magnets for Hall sensors and motor rotors, reporting improved efficiency and longer lifespan. Moreover, our GBD process supports sustainability goals by minimizing reliance on scarce heavy rare earths. With patents filed and ongoing research into nano-diffusion variants, IT-MAG continues to push the boundaries of what’s possible in permanent magnet technology.

The challenge: create a small, high-strength magnetic assembly that wouldn’t interfere with imaging while maintaining precise positioning. Our team designed a miniaturized NdFeB magnet array with a Ni-Cu-Ni-Au coating (5–20μm thickness), offering both high electrical conductivity and biocompatibility. The assembly passed FDA and CE regulatory testing and was integrated into the device, improving accuracy by 30%. In another case, a construction equipment firm needed a magnetic clutch for a high-load hydraulic pump. Standard magnets failed due to heat and mechanical stress. We developed a custom magnetic assembly using GBD-treated N52KH magnets with epoxy resin coating (15μm), providing superior thermal resistance and binding strength. Field trials showed zero failure over 2,000 hours of operation.
