On May 20, 2024, Tianjin Ruiyuan Electrical Engineering Materials Co., Ltd. held a fruitful video conference with DARIMAX, a renowned German supplier of high-purity precious metals. The two sides conducted in-depth exchanges on the procurement and cooperation of 5N (99.999%) and 6N (99.9999%) high-purity copper ingots. This conference not only deepened the business ties between the two parties but also comprehensively demonstrated the production process of high-purity copper ingots via video link, laying a solid foundation for future cooperation.
Strong Partnership, Joint Pursuit of Development
As a global leader in high-purity precious metal supply, Germany’s DARIMAX holds worldwide prestige in rare metal purification and high-end industrial materials. Tianjin Ruiyuan Electrical Engineering Materials Co., Ltd., a professional import-export enterprise with 22 years of history, has accumulated extensive experience in non-ferrous metal trade. Focusing on high-purity copper ingots, the two sides held detailed discussions on key issues such as product specifications, quality standards, and supply cycles during the conference, and reached preliminary cooperation intention
“Virtual Tour” of the Full Production Process, Quality Earns Trust
To ensure that Germany’s DARIMAX fully understands the product quality, Ruiyuan Electrical Engineering specially arranged a “virtual tour” activity. Through video live streaming, Ms. Ellen and Ms. Rebbce from the company’s foreign trade department demonstrated the complete production process of high-purity copper ingots—from raw material selection to finished product packaging—to the German side.
1.Raw Material Selection
The conference first introduced the sources of raw materials for high-purity copper ingots, emphasizing the strict selection of high-quality electrolytic copper to ensure the initial purity meets the highest industry standards.
2.Precision Production Processes
Subsequently, the video shifted to the smelting, casting, and purification workshops, showcasing advanced vacuum smelting technology and zone melting processes. These ensure the copper ingots stably achieve purity levels of 5N (99.999%) and 6N (99.9999%).
3.Rigorous Quality Inspection
During the quality control segment, Ruiyuan Electrical Engineering highlighted the use of high-end testing equipment such as GDMS (Glow Discharge Mass Spectrometer) and ICP-MS (Inductively Coupled Plasma Mass Spectrometer). This ensures that the impurity content of each batch of copper ingots meets customer requirements.
4.Professional Packaging and Logistics
Finally, the German side observed the product packaging process, including anti-oxidation treatment and customized wooden box packaging, to ensure safety during transportation.
The representative of DARIMAX highly praised Ruiyuan Electrical Engineering’s rigorous production management and high-standard quality control system, expressing anticipation for further cooperation.
5.Deepening Cooperation and Looking to the Future
This video conference was not only a product demonstration but also a significant step toward establishing a long-term partnership. Mr. Yuan, General Manager of Ruiyuan Electrical Engineering, stated: ”We attach great importance to the cooperation opportunity with DARIMAX. This ‘virtual tour’ allowed customers to intuitively understand our technical capabilities and quality commitments. In the future, we will continue to optimize production processes to provide global customers with higher-quality high-purity metal materials.”
Mr. Kasra, the Procurement Director of DARIMAX, also expressed satisfaction with the conference results, emphasizing: ”High-purity copper ingots are critical materials for the precision electronics and semiconductor industries. Ruiyuan Electrical Engineering’s production capacity and quality management are impressive, and we believe the cooperation between the two sides will achieve mutual benefit.”
With the continuous growth of global demand for high-purity metals in advanced manufacturing, this conference has opened a new chapter in the collaboration between the two enterprises. In the future, both sides will deepen cooperation in technical exchanges, market expansion, and other areas to jointly promote the international development of high-purity metal materials.
