Latest Patents

One of Kunugiza's latest patents is focused on a hot forming mold and the method of manufacturing it. This invention utilizes xonotlite group materials, such as xonotlite and 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, he has developed a mold that exhibits increased bending strength and hardness. The manufacturing process involves filter pressing an aqueous slurry of xonotlite, followed by drying the pressed product at temperatures below 700°C. The mold can then be machined and used for superplastic forming of metals like aluminum and titanium after heat treatment at temperatures between 700°C and 1200°C.
