Our company integrates design, research and development, innovation, production and marketing: relying on the international market, taking high-tech talents as the cornerstone, taking the latest technology as the driving force, taking the self import and export rights as the channel, committed to the research and development of high-tech products.

Our company was the first one to develop sealing products for domestic steam locomotives and diesel locomotives. We have provided the seal of 1000-10000 tons forging machinery for China that achieved the record of zero leakage for more than ten years. We have developed high-end seals for photovoltaic in China and corresponding products for the fourth generation of nuclear power.
