ABOUT Niimi Sangyo

Niimi Sangyo Co., Ltd. is a material manufacturer that uses plasma melting technology. The high-frequency induced thermal plasma becomes an ultra-high temperature exceeding 10000 ℃. The spheroidization technology for refractory materials (metals and ceramics) using the plasma will be the only one technology in Japan.
In 2019, Niimi Sangyo Co., Ltd. took over the plasma melting business from Daiken Chemical Co., Ltd. After the business succession, Kadotoku will be the sole distributor worldwide for materials manufactured using plasma melting technology.
