Latest Patents
Miyauchi's latest patents demonstrate his focus on improving mold performance. One of his innovations is the "Mold for casting and method of surface treatment thereof." This patent details a method for treating the cavity surface of molds made from SCM420 material. The process includes first shot peening, followed by a sulfurizing-nitriding treatment, and a second shot peening. This results in a cavity surface exhibiting a Vickers hardness of 700 or higher, with a compression residual stress exceeding 1200 MPa and a surface roughness value of 8 µm or less.
His second patent, titled "Mold for casting and method for manufacture thereof," introduces a mold primarily made from SMC420 that features a cavity forming portion made of maraging steel. This steel offers superior toughness and heat shock resistance, particularly at the cavity surface areas that experience significant heat exposure from molten metal contact. The method encourages the use of overlaying welding to fill concave portions of the mold, enhancing its resilience during the casting process.
