Usugi Denkai Kougyou Co., Ltd.

We are a comprehensive surface treatment manufacturer that was established in 1958. Our company employs various surface treatment technologies to meet various customer needs. These include low-temperature black chrome treatment for machined parts, Sn plating for electric components, and other original technologies that we developed independently. Our low-temperature black chrome plating realizes a thin (1 to 2 �m) and even film thickness. This plating is adopted for a wide range of applications because of its characteristics (including low light reflectivity, high adhesion, and high corrosion resistance), which contributes to our company�s performance. We also manufacture electronic components, circuits, and devices.
