Professional of extra fine line spring

We coil the smallest spring in the world. Placing a special emphasis on the stable repeatability.

For the good of customers and society, our goal is to be a technical expert group in the field of fine spring manufacturing, having a strong will to keep challenging to make impossible possible.

We are very glad to announce that Ocean’s Corporation was established in Feb. 2009.
For ten years, I, Atsushi Akagi, have been engaged in planning and selling springs to probe pin manufacturers, electronic parts manufactures and medical-device manufacturers in Japan and overseas. During the last phase of my previous career, I also worked as a member of R&D team,
and was involved in studying materials and manufacturing processes of fine springs.
I decided to begin the business, to keep challenging to myself utilizing my rich experiences in prototype tests of the fine springs, which are considered as difficult products to handle in the industry. I would like to work even harder than ever to satisfy your needs.
