Factory History:
Our factory was established in 1987. At first we mainly produced railway signal system products, and then developed hydraulic electronic circuit breakers, and succeed in 2001. We have gained more than a dozen countries' technology patents. For a small-scale private enterprise, it is absolutely an unbelievable glory. However in 2003, our factory was in the brink of bankruptcy because of market and financial reasons. Our manager determined to switch to the aluminum die casting industry.
