Tongding Interconnection Leads Investment Round as Jiangsu Mrisen Secures Tens of Millions in Funding, Pioneering Domestic Production of Ultra-High-Purity Materials

  Recently, Jiangsu Mrisen High-tech Materials Co., Ltd. (here inafter "Mrisen") successfully completed a financing round raising tens of million yuan, with Tongding Interconnection Information Co., Ltd. (002491), existing shareholder Suzhou Jundding Fund, Chengdu Jingtai Investment Development Co., Ltd, and other investors participating together in this round.This financing reflects the capital market's recognition of Mrisen's technological strength and potential, and will further inject momentum into capacity expansion, technological iteration, and market development, helping to consolidate its leading global position in high-purity metal technology.

A cutting-edge technology innovator deeply engaged in the field of ultra-high purity materials

  Mrisen, a high-tech enterprise established in Kunshan, Jiangsu in 2023, focuses on the research、development, and production of ultra-high-purity base materials. Its core products feature technologies surpassing international standards, with current annual production capacity of 70 tons of 7N+ ultra-high-purity copper and 3,200 tons of high-purity copper sulfate solution.

Technology Leading , setting the benchmark for quality

  Technological innovation is the core competitive advantage, with product purity and quality leading globally. Mrisen's ultra-high-purity copper maintains a stable purity level of 7N–8N, with some batches reaching 9N grade; its high-purity copper sulfate has a total cation content of ≤1 ppm, creating a significant technological gap compared to competing products. The products have passed verification by national authoritative institutions. Leveraging its technological strengths, Mrisen has become a key compliant supplier of high-purity copper for nuclear fusion devices, ensuring material supply for China's major scientific installations in nuclear physics.

Market Recognition, Breakthroughs Across Multiple Fields Achieve Domestic Substitution

  Technological advantages have been transformed into market competitiveness, with products gaining recognition from leading institution customers across multiple high-end sectors. High-purity copper sulfate、 copper wire、 copper targetsand phosphorized copper anodes have passed certifications from several leading FAB institution . The phosphorized copper anode made from 7N high-purity copper demonstrates superior performance.

Looking ahead, empowering independent and controllable advanced manufacturing.

  Regarding future development, Mrisen stated that the funds raised will be primarily allocated to three key areas: first, expanding the production capacity of ultra-high-purity copper to meet growing market demand; second, increasing investment in research and development to tackle higher-purity materials and novel manufacturing processes; third, expanding global distribution channels and deepening cooperation in cutting-edge fields. As one of the few global suppliers capable of serving multiple advanced sectors, Mrisen will continue to focus on the domestic production of high-end materials, break international monopolies, and contribute to China's self-reliance and control in advanced manufacturing.
