Ningbo Dacheng, established in 1985,was the first "national key high-tech enterprises" and "national-level innovative enterprises". It is the earliest (1996) technology-based enterprise engaged in the development and production of ultra-high molecular weight polyethylene fibers and its high-performance bulletproof composite materials in China.
      The company ,whom developed itself by" science and technology” always adheres to the combination of independent innovation and "production with research cooperation”.It has successively established a post-doctoral research station, high-performance fiber and composite materials engineering and technology centers and etc.It had already implemented three national high-tech “863” plans, three national high-tech research industrialization projects, and one national major scientific and technological research project.It has accumulatively applied and authorized 26 national invention patents, 17 utility model patents, 4 international PCT patents, and 1 U.S. patent.It already passed ISO9001 international quality system certification, GJB9001A military product quality management system certification. In 2015, the company obtained certification for national confidentiality qualification at level three, and obtained the qualification certification of the weapons and equipment manufacturing unit in 2016.In 2005 and 2008, it was listed as the National Bulletproof Equipment Mobilization Center and the mobilization base for the development and manufacturing of bulletproof equipment in the Nanjing  Military Area. In 2017, it was listed as the first batch of military-civilian integration demonstration enterprises in Zhejiang Province.In 2005,it was awarded first prize for scientific and technological progress in Ningbo, the first prize for scientific and technological progress in Zhejiang Province, and the second prize for national scientific and technological progress in 2009.
