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 µm) 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.
