The introduction of international advanced level sheet metal mold sprints made the quality level of graphite metal composites for automotive gaskets in line with the rest of the world.

The self-developed localized automatic winding machine has been successfully tested. At the same time, various types of anti-corrosion gaskets and packing for valves have been successfully tested, major breakthroughs in corrosion resistance and high temperature resistance, filling the gaps in high-end sealing of graphite products in China.

Successfully tested and manufactured anti-oxidation graphite plates and corrosion-inhibiting graphite plates, filling a gap for graphite products in China.

We purchased several advanced inspection instruments from abroad to ensure that our physical and chemical indicators and sealing performance are fully controlled.

Since the introduction of internationally advanced automatic winding machines and fully automatic filling machines from Europe, our company’s nuclear level sealing products have been synchronised with the rest of world.

Our self-developed flexible graphite sheet production line has been successfully tested, major performance indicators have shown to match or exceed the level of the imported production line.

The company introduced automatic winding machines with advanced international standards from Italy, which has made it possible to produce high-quality spiral wound gaskets within China.

The “Nuclear-grade valve packing and gasket” project developed in cooperation with the Shanghai Nuclear Industry Institute and the Qinshan Nuclear Power Plant passed inspection and acceptance and filled the void of the domestic-made nuclear power seals. The “Double Peaks” brand nuclear-series sealing products were widely used in Qinshan Nuclear Power Station, and were widely adopted by the Daya Bay Nuclear Power Station, Tianwan Nuclear Power Station, and Nanjing Chenguang.

China’s First Ministry of Machinery Industry organized domestic experts to manage foreign materials at the Daya Bay Nuclear Power Station. Our company is responsible for data collection and transformation of sealing materials, opening the door for nuclear power to our company.

First Chinese company to introduce Japan’s flexible graphite sheet production line, this enabled China’s flexible graphite sealing material manufacturing to be among the international elite.
