About US

To Achieve our Vision

In 1975, TOYO SEIKO CO., LTD was established to manufacture and sell steel cut wire shot for de-scaling machine of Miyazaki Seiko Co., Ltd. Furthermore, we expanded our business to "Peening", which is surface treatment for parts enhancement, for not only to automotive industry but also to aviation industry and nuclear power field keeping our business stability and expansion. During all that time, we developed not only peening shot media, but also ultrasonic peening equipment and other peening related inspection equipment. Moreover, we tried promoting services such as peening services for aircraft parts (Nadcap certified) and on-site peening process for bridges and shipbuilding.
