--- Innovative Production Process at IT-MAG ---
• Advanced Manufacturing Techniques:
IT-MAG’s production process is a masterclass in precision engineering, meticulously designed to transform raw rare-earth materials into high-performance neodymium magnets. From the initial raw material blending to final magnetization, each step is optimized for consistency, strength, and durability. The process begins with strip casting, where molten NdFeB alloy is rapidly cooled into thin ribbons, preserving microstructural integrity. This is followed by hydrogen decrepitation—a unique method that breaks down the alloy into fine particles without oxidation, ensuring purity. Jet milling then reduces the particles to sub-micron levels, enabling uniform distribution during pressing. The core of IT-MAG’s advantage lies in its use of magnetic field forming presses and automatic isostatic presses, which align magnetic domains precisely during molding, significantly enhancing the final magnet’s coercivity and remanence. After pressing, the green compacts undergo germ inspection and vacuum sintering at temperatures exceeding 1,000°C, fusing the particles into a dense, crystalline structure. Subsequent machining, surface treatment, and final inspection ensure dimensional accuracy and corrosion resistance. Every stage adheres to the mantra: 'Strong magnets for strong products.' Notably, IT-MAG’s integration of Grain Boundary Diffusion (GBD) technology allows for the creation of ultra-high-coercivity grades like N55H—previously unattainable through conventional methods. This proprietary process enables manufacturers to reduce heavy rare-earth content by up to 30% without sacrificing performance, making IT-MAG’s solutions both sustainable and cost-effective. The entire process is monitored in-house with real-time data logging, ensuring traceability from batch to delivery. This level of control ensures that every magnet shipped meets or exceeds customer expectations—whether for medical devices requiring biocompatible coatings or industrial tools operating in harsh environments.
• Quality Control Measures and Equipment:
At IT-MAG, quality is not an afterthought—it is embedded in every phase of production. The company operates a state-of-the-art laboratory equipped with cutting-edge analytical instruments to verify material composition, magnetic properties, and environmental resilience. Key testing equipment includes a high-frequency infrared carbon and sulfur analyzer, X-ray fluorescence spectrometer, and inductively coupled plasma mass spectrometer—all critical for detecting trace impurities that could degrade magnetic performance. Magnetic force tests are conducted using automated fluxmeters to measure remanence, coercivity, and energy product with ±0.5% accuracy. Environmental stress tests are equally rigorous: salt spray tests (SST) and humidity exposure (PCT) simulate decades of aging in just days. For example, Ni-Cu-Ni-Au coated magnets must withstand ≥96 hours in PCT chambers and ≥72 hours in salt spray, proving their suitability for automotive and aerospace applications. Additionally, IT-MAG conducts high and low-temperature impact tests, cycling samples from -40°C to +150°C to validate thermal stability. All results are logged in a digital quality management system, allowing full traceability back to raw material batches. The lab is marked 'Lab' and assigned internal reference number 03-280, reinforcing IT-MAG’s internal standards. These measures are not only compliance-driven but also customer-centric—especially vital for clients in the medical device sector, where failure is not an option. One notable case involved a leading European medical imaging company that required magnets with zero risk of demagnetization during MRI procedures. IT-MAG delivered custom N48H magnets with GBD treatment, passing all certification requirements and reducing the risk of field drift by over 90%. Such outcomes are possible only because of IT-MAG’s unwavering commitment to quality control and continuous improvement.

• Investment in Innovative Technologies:
IT-MAG’s leadership in the neodymium magnet industry is fueled by a relentless investment in research and development. With a team of over 30 R&D engineers and access to the ZOEHIGH Group’s vast raw material resources, IT-MAG continuously pushes the boundaries of what’s possible in magnetic technology. The company allocates a significant portion of its annual revenue to innovation, focusing on next-generation materials, energy efficiency, and sustainability. One of the most impactful breakthroughs is the Grain Boundary Diffusion (GBD) process—an advanced technique that enhances coercivity without compromising magnetic strength. By selectively diffusing heavy rare-earth elements like Dysprosium (Dy) and Terbium (Tb) into the grain boundaries of sintered NdFeB magnets, IT-MAG achieves higher performance grades such as N55H, N52UH, and N48KH—grades previously limited by material scarcity and cost. This innovation allows customers to design smaller, lighter, and more efficient motors and sensors, crucial for EVs and robotics. IT-MAG’s GBD process has been validated through extensive testing under extreme conditions: magnets treated with GBD maintain >90% of their magnetic properties at 150°C, compared to <60% for untreated counterparts. Beyond GBD, IT-MAG explores alternative coatings like Parylene and Everlube, which offer superior resistance to moisture, solvents, and corrosive vapors—ideal for marine and aerospace applications. The company also invests in AI-driven simulation tools to predict magnetic behavior before physical prototyping, accelerating time-to-market. These efforts have led to multiple patents and industry awards, reinforcing IT-MAG’s position as a technology leader. Real-world validation comes from projects like the Ferrari brake-Hall sensor system, where IT-MAG’s GBD-treated magnets ensured stable signal output under intense heat and mechanical stress. Such achievements demonstrate that IT-MAG doesn’t just follow trends—it sets them.
• Grain Boundary Diffusion (GBD) Process Explained:
The Grain Boundary Diffusion (GBD) process is a cornerstone of IT-MAG’s technological edge, enabling the production of high-coercivity neodymium magnets with reduced reliance on expensive heavy rare earths. Unlike traditional doping methods that uniformly distribute Dy/Tb throughout the magnet, GBD targets only the grain boundaries—the interfaces between magnetic crystals—where coercivity is most sensitive. The process begins with pre-treatment to remove oil and scale, followed by coating Dy/Tb onto the magnet surface using precision vapor deposition. The coated magnets are then heated in a vacuum furnace at 700–1000°C, allowing the heavy rare-earth atoms to diffuse inward along the grain boundaries. This creates a high-gradient magnetic barrier that resists demagnetization, significantly increasing intrinsic coercive force (Hci) without weakening the magnet’s remanence (Br). The result? Magnets with grades like N55H and N52UH—previously unachievable with standard sintering. IT-MAG’s GBD process is highly tunable, with temperature ranges from 80°C to 260°C, allowing customization for specific performance needs. For example, magnets treated at 150°C show a 30% increase in Hci compared to untreated ones, maintaining over 90% of their strength even after prolonged exposure to high temperatures. Data from internal testing shows that after GBD, a magnet’s residual loss drops from 1.2 kg to 0.9 kg at 120°C and from 12 kg to 1.5 kg at 150°C—demonstrating remarkable thermal stability. This technology has revolutionized motor design in EVs and wind turbines, where efficiency and longevity are critical. IT-MAG’s GBD-treated magnets are now used in high-end automotive sensors, industrial actuators, and aerospace systems. With the ability to reduce Dy content by up to 30%, GBD also supports sustainability goals, making IT-MAG a preferred partner for eco-conscious manufacturers. This innovation underscores IT-MAG’s mission: to deliver stronger, smarter, and more sustainable magnetic solutions worldwide.
