Ningbo Tiansheng Seals Co., Ltd. was established in 1998. It is a technology-oriented high-tech enterprise, mainly engaged in the research and development, technical support and program design of sealing technology systems in the nuclear industry, military industry, aviation, aerospace, shipbuilding, petrochemical and other related fields. The company is a national high-tech enterprise, a Zhejiang Province military-civilian integration demonstration enterprise, a qualified supplier to the petrochemical industry, nuclear power plants, and large equipment factories. It has overcome the technological restricted area that has been monopolized by foreign companies for decades: it has successfully developed O-type and C-type sealing ring products, achieved a number of innovative results, and has independent intellectual property rights, completely breaking the monopoly of foreign companies on this type of sealing technology. We are the leader in the localization of China's static sealing industry.
