With a total of 2 patents, Tsukiyama's work focuses on enhancing the efficiency and effectiveness of manufacturing processes.
Latest Patents
One of Tsukiyama's latest patents is for a hot forming mold and method of manufacturing the same. This invention provides a hot forming mold made of xonotlite group materials, such as xonotlite or wollastonite, which are recognized for their heat-resisting properties. By hot pressing these materials to achieve a high bulk density ranging from 0.6 to 2.20, a mold suitable for hot forming can be efficiently produced. The process involves filter pressing an aqueous slurry of xonotlite, drying the pressed product to remove moisture at temperatures below 700°C, and then cutting out the mold for use in molding plastics, glass, and similar materials. Furthermore, by heat treating this mold product at temperatures between 700°C and 1200°C, the resulting mold can be machined and utilized for superplastic forming of aluminum, titanium, and other materials.
