Spring‑light tech pursues global leadership by focusing on segmented soft‑magnet materials

Han Weidong, director of Shandong Chunguang Science and Technology Group Co., Ltd., shared the enterprise's development philosophy of “digging one‑meter‑wide track for one‑hundred‑meter‑deep expertise”. Rooted in Yimeng mountain area, the firm strives to become a world‑leading manufacturer of soft‑magnetic materials.

On May 11, 2026, Chunguang Science and Technology was listed on the ChiNext board of Shenzhen Stock Exchange, becoming Linyi's first ChiNext‑listed enterprise in nearly five years. Its first financial report after listing shows operating revenue of 745 million yuan, a year‑on‑year increase of 36.32 percent; net profit reached 74.945 million yuan, up 28.09 percent year‑on‑year.

Rather than chasing diversified expansion, the enterprise concentrates on soft‑magnetic material, a key foundational material widely applied in new‑energy vehicles, photovoltaic energy storage and AI servers. It has built 15 fully‑automatic magnetic‑powder production lines with annual capacity of 150,000 tons, forming a product matrix covering seven major series and more than 50 varieties. Magnetic‑powder sales have ranked first nationwide for three consecutive years, with over 20 percent domestic market share in soft‑magnetic ferrite materials.

Breakthroughs have been achieved in core technologies. Its ultra‑high‑permeability manganese‑zinc ferrite material reaches an initial permeability of 25,000. Wide‑temperature low‑loss products can adapt to 800V high‑voltage platforms for new‑energy vehicles, reaching internationally advanced standards. Moreover, the international standard for ferrite magnetic cores, led by Chunguang, has passed voting and project initiation by International Electrotechnical Commission, marking a shift from following international standards to setting industry benchmarks.

Han Weidong noted that the Yimeng spirit endows the enterprise with perseverance, empathy and enterprising drive. Supported by Linyi's “Langya listing support plan” and policy‑oriented service mechanisms, the firm completed its IPO registration procedures within less than nine months.

As a representative of “new Linyi merchants”, Chunguang integrates itself into national innovation systems, transforms from factor‑driven to innovation‑driven growth, makes use of capital markets and strives to drive the whole industrial chain. The company aims to build a world‑class magneto‑electric manufacturing base in Linyi.
