Our first generation chain factory started in 1999. Our founder Mr Ying Li resigned from a local state-owned chain factory and started the business with 3,000 RMB. At that time, we could only produce chains without welding. A few years later, we purchased a manual welding machine. At this time, we had just caught up with the average level of local chain factories. We could produce chains with unsmooth welding and no breaking load requirements. Our second generation chain factory was established in 2008. At that time, Mr. Ying Li believed that the coal mining market was promising, so we took out a loan to purchase large-size bending machines and semi-automatic welding machines. We started producing mining chains of grade B. A few years later we bought our first heat treatment equipment and we started producing mining chains of grade C and lifting chains of Chinese standard.

We are now a modern factory with a full automation rate of 80%. In 2017, we already had the most advanced fully automatic chain production equipment, for example, fully automatic bending machines, fully automatic welding machines, fully automatic calibration machine, fully automatic temperature-controlled medium-frequency heat treatment furnaces, and a full set of experimental equipment. This marks a leap forward in our production efficiency and stability. We are no longer satisfied with producing ordinary chains. High-strength chains are our main products now:

We will increase our automation rate again in the future, which will not only improve our pass rate but also improve our production efficiency. Our industry is heavily dependent on electric drive, and now we are promoting 0 carbon emission production. We cooperate with local photovoltaic panel production companies to convert all production electricity from coal-fired power generation to solar power generation. This makes our development more sustainable and more protects our environment.
