Company Introduction:
Binzhou Aonuo New Material Technology Co., Ltd. Established its first company in Zibo on June 7, 2017, with a registered capital of 30 million. The company is committed to the development of the precision electronic ceramic substrate industry at home and abroad. It has new ceramic materials, powder preparation technology, a variety of advanced molding technologies, and high-temperature ceramic kiln sintering technology, which can meet the electronic functional parts and new functional materials required by various industries. Production applications, high-tech products have been expanded to mobile phones, electronics, electrical engineering, communications, machinery, environmental protection, new energy, biology and other application fields.
After years of technological accumulation and innovation, the company′s high-tech products have formed a multi-category product structure dominated by ceramic components, alumina ceramic substrates, LED filaments, ceramic substrates for resistors, etc.
In order to subsequently adjust the product structure, Aonuo New Material Technology Co., Ltd. Established a second company in Binzhou on March 27, 2020, with a registered capital of 20 million. In addition to expanding the output demand of alumina ceramic substrates, it will also increase production in the future. Great efforts in R&D and production of aluminum nitride and silicon nitride;
