Department of Materials Science and Processing

Materials Processing Division

Materials Processing Division


The Materials Processing Division provides basic education regarding manufacturing based on mechanical engineering, such as design mechanics and computer-aided design engineering that clarify fracture events of materials to assist with product design, and production-processing science that is directly related to product manufacturing. We also perform the latest education and research to develop advanced design and production technologies of new materials, and the design, production, and processing techniques essential for applying those materials to new products. Through collaborative subjects with other departments, we incorporate the fields of energy conversion and intelligent machines, for example, developing environmentally friendly design technology and production systems based on information technology.
