Latest Patents
Tomita's latest patents include a high-pressure casting method and a high-pressure casting device. These inventions are designed to enable safe and high-quality casting of high-fusion-point metals, which have fusion points exceeding 1000 K. The method involves melting a casting material inside a cartridge-type melting container, which is then linearly moved to communicate with a casting port bush. This process ensures that the molten metal is pressurized and injection-filled into a cavity, resulting in superior casting quality.
Another significant patent is for a dissimilar metal joint product made from nickel-titanium alloy and pure titanium. This joint product boasts a tensile strength at the joint that is not less than that of the pure titanium material before joining. The method for creating this joint involves frictional pressure welding, where one of the joining faces is rotated while applying a specified upset force. This innovative approach minimizes the heat-affected zone and enhances the strength of the joint.
