Company information
Maruhi Co., Ltd. was established in 1968 in Kamikugen, Iida City, as Maruhi Electric Manufacturing Company, primarily assembling instrument motors. With the arrival of a new era, we changed our company name to Maruhi Co., Ltd. to bring innovation to manufacturing and respond to the diverse needs of this new age, aiming for further development of our business. In 1999, we constructed our long-desired state-of-the-art factory in Kiririn, Iida City. Since our founding, we have responded to the needs of various fields, primarily in FA-related equipment, as experts in precision motor manufacturing, including electronics and automotive sectors. We have always played a pioneering role in introducing the latest equipment such as various NC machines and acquiring the latest technologies. We established a consistent production line from parts processing to assembly of motors and encoders, obtained ISO 9002 in March 1999, transitioned to ISO 9001 in July 2006, and acquired ISO 14001 in March 2001, receiving high evaluations for our operations. With the change of our company name, the completion of the new factory, and a renewed determination to soar into the next generation, we are committed to "manufacturing for a new era" and striving for even higher reliability, performance, and quality in our production.
