Abstract:  
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.
