Quality Policy

To maintain consistency of quality and service, whole series of transformers were changed to sealed type since 2005, which not only extends the products' life but also improves insulation.

All of our products have been manufactured in Taiwan since the company was founded, so naturally our labels read "Made in Taiwan." Sadly, many businesses in our line of work deceive customers by using label " Taiwan." Therefore, STON decided to stay in Taiwan, setting up a second plant in San Chong, Taipei, which also ensures our products are good and customers can set up a long term relationship with us without worrying.
