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.
Niimi Sangyo Co., Ltd. started plasma melting business in 2019. After the start of the business, Kadotoku Corporation will act as an exclusive agent in Japan and overseas for materials manufactured using plasma melting technology.
