Latest Patents

Among his latest patents, Oohira introduced a groundbreaking method for producing machine components. This method focuses on manufacturing machine parts with a radial crushing strength of 120 MPa or more. It includes a compression molding step that compresses a raw material powder, primarily metal powder with a high ratio of pure iron powder (95 mass % or more), to create a green compact. The next phase involves heating the green compact in an oxidizing gas atmosphere at a temperature below the metal powder's sintering point, resulting in a reinforced green compact characterized by an oxide coating between the metal powder particles.

Another notable patent concerns the development of a sintered compact with a density of 7.5 g/cm³ or more, obtained from a mixed powder of graphite and diffusion alloyed steel powder. By carefully controlling the ratio of graphite powder (between 0.05 wt % to 0.35 wt %), he has paved the way for enhancing the properties of sintered machine parts. His dedication to innovation not only helps create stronger materials but also contributes to more efficient manufacturing processes.
