R&D Honors
Under the four-round promotion of constructing innovative scientific research institutions, research personnel training, innovative talent incentive mechanism, and innovation achievement evaluation, in 2010, the company's large-scale ultra-high power graphite electrode project has been included to the National Torch Program of the Ministry of Science and Technology and won the National Science & Technology Progress Award (second class) from All-China Federation of Industry and Commerce. In the same year, we were listed by the government as the first batch of strategic emerging industry project contractors in Sichuan Province. Meanwhile, the company's intellectual property construction has also leaped to a new level. From the couple of years recently, Shida has obtained 13 patents in the high-end carbon field, supporting the steady improvement of enterprise's quality connotation and technology content through innovation and scientific research.
