Sako group enterprise is a private owned enterprise and was established in 1993, . The original factory building was located in the Liushi City of Wenzhou in China. Owing to being too busy to make proper response to the numerous orders, and the premise that the factory building and the facilities needed the expansion, the company was moved to the Yueqing Central Industrial Park in 2004. We commit ourselves to the R&D and manufacture of the power supply and electrical testing equipment. Our annual business volume continues growing steadily, and our goal is to strive for the greatest competitive superiority.
