Large-scale equipment developed by Rinashimetari

Rinashimetari (Chuo-ku, Fukuoka City) has developed a large-scale device that uses metal processing heat treatment technology. It can handle bars up to 70 mm in diameter, and heats and shears the metal to increase its strength. The company aims to use the equipment for processing parts for aircraft and railroads, as well as frames for small electric vehicles (EVs). The technology used in the equipment is called "RMA-CREO," which heats metal bars at high frequency, rapidly cools both ends, and then applies torsion and shearing to refine the crystal grains. The equipment will be installed by Mimatsu (Chikushino City, Fukuoka Prefecture) at its Yosu Plant (Chikuzen Town, Fukuoka Prefecture), and Mimatsu will undertake the production.
