TOYO SEIKO is celebrating its 50th anniversary in 2025. The company was founded in 1975 as a manufacturer of cut wire media for mechanical descaling machines for wire rods manufactured by its parent company, Miyazaki Seiko.
After 10 years, Toyo Seiko entered the shot peening field, and in 1989 we completed manufacturing Japan’s first high-hardness conditioned cut wire shot by collaborating with Toyota Motor Corporation. Since then, we have expanded our business by focusing on the shot peening field.
Under the philosophy of “Make anti-shot-peening fans to fans,” we have developed original inspection equipment such as Coverage Checkers, various peening devices such as air-type needle peening devices, and high-durability cut wire shot to satisfy our customers’ needs and contribute to the peening industry’s development.
In 2006, we began the contract peening processing for aircraft parts as a shot manufacturer, and in 2015 we were able to expand this business into the Mitsubishi Regional Jet project which Mitsubishi Heavy Industry started.
Since 2010, we have been proactively working to expand our business overseas in response to the globalization of our customers. We have established our first overseas affiliate in Thailand in 2011 and another one in the United States in 2014 These expansions enable us to produce our cut wire meet to customers’ demand worldwide.
As a result, our annual sales volume has exceeded 15,000 tons, and global market share has grown to 35%. In addition, Toyo Seiko has been proudly selling the Electronics Inc. (EI) Almen strips and MagnaValve® in Japan as an official sales distributor since 2005 and we have sponsored EI’s shot-peening workshops in Japan for decades.
Our company seeks new growth with the vision of “Continuous contribution to the peening society as an ambassador for surface enhancement technology.” We aim to be a company that can be trusted as an indispensable partner by our customers by providing innovative imagination while flexibly responding to changes in the market.
Furthermore, we commit to be a company that is responsible for both people and society by developing environmentally friendly equipment, such as the Dust Solidify Device that helps reduce CO2 emissions, and creating a work environment where people can feel happy.
