Strengthening Supply Chain Excellence: AT&M Visits Dongguan JH Amorphous

We were honored to recently welcome a delegation from AT&M, one of China's leading suppliers of nanocrystalline and amorphous ribbons, to Dongguan JH Amorphous. This visit not only marked another milestone in our four-year strategic partnership but also reaffirmed our shared commitment to innovation, quality, and supply chain integration.

The factory tour provided an excellent opportunity to showcase our end-to-end production capabilities, from material handling and processing to core forming, case assembly, and final product testing. Our team highlighted the strict raw material management protocols we have in place, ensuring every coil of ribbon entering our factory meets exacting standards for magnetic performance and consistency.

AT&M’s representatives expressed high recognition of our supply chain strength, particularly our ability to maintain traceability and quality control throughout the entire manufacturing process. By working closely with top-tier material suppliers like AT&M, we ensure raw material stability, which is the foundation of our core performance and long-term reliability.

They were also impressed by the automated manufacturing systems in use across our facility, which allow us to scale production rapidly without compromising precision. Our investment in advanced production lines ensures we can meet growing global demand while maintaining cost efficiency and delivery timelines.

During the visit, both teams engaged in technical discussions focused on improving core performance and cost optimization. Topics included exploring alternative raw materials, minimizing production waste, and integrating eco-friendly practices into our manufacturing. AT&M acknowledged our proactive approach to balancing cost control with premium product quality—a key driver in today’s competitive power electronics market.

More importantly, the visit emphasized the value of co-engineering. We explored collaboration opportunities on developing application-specific nanocrystalline cores for high-frequency power conversion, EV charging, and high-power transformers. AT&M showed strong interest in joint R&D to align materials and processes for optimized end-use performance.

Looking ahead, Dongguan JH Amorphous will continue to strengthen its position as a trusted nanocrystalline core supplier by focusing on:

• Raw Material Excellence: Enhancing quality through supplier partnerships and rigorous material screening.

• Performance Optimization: Tailoring magnetic properties to meet the needs of emerging high-frequency and high-power applications.

• Supply Chain Integration: Leveraging vertical coordination with material providers like AT&M for better quality and delivery control.

• Sustainability Commitment: Reducing environmental impact through process improvement and green material exploration.

This successful visit reaffirms our dedication to quality, innovation, and supply chain transparency, and we believe our collaboration with AT&M will help drive the next generation of high-performance, cost-effective magnetic solutions.
