"RAYDENT Metareatment" is a special surface treatment technology to form an alloyed surface of metallic materials by means of electroplating. Regarding "the RAYDENT surface improving design method," "the infinite dispersion potential theory" and "the high life and life extension engineering," which contribute to the world in the field of manufacturing technology of state-of-the-art high precision electronic equipment as typified by semiconductors and flat-screen televisions. We are also developing technical cooperation operations as the RAYDENT Metareatment Operational Headquarters.
