Pres. Message

Since the institution’s formation of mainly processing operation of electrical manufacture in 1950, we have practiced the idea that is to realize quality and improvement without losing sight of basic points.
For coping with demands from customers, we focus on improving electric skills mainly of an insulating process. Moreover we’ve been expanding business to various electrical coupling parts and coils for rotary machines (rotator, stator coil), electromagnetic coil and transformer coil including a variety of insulating.
We accumulate technology and know-how steadily, and we stretch from coil assembly to fabrication of electric motor and generator to meet our customer’s needs.
We took out ISO9001 (International Standard of quality management system) in 2007 and KES (KES Environmental Management System Standard) in 2008, and we emphasize CRS (Corporate Social Responsibility) for customer satisfaction.
From now on we assure that we’ll provide more customers with significant benefit in creative ways through manufacturing. We’ll work forward as a company which can contribute to society. We look forward to your continued support.

President: Seiichi Hotta
