Latest Patents

His latest patent, titled "Composite Metal Molding and Method for Manufacturing Thereof," addresses the challenges associated with creating compression moldings that exhibit both high dimensional accuracy and mechanical strength. Traditional powder molding processes struggle when manufacturing moldings that include soft magnetic materials with superior properties. In this innovative approach, Junji Hamana presents a composite metal molding that integrates metal particles and the carbide of resin. The methodology includes coating metal particles with resin, then molding the prepared material under pressure, followed by a heating process that calcines the resin and welds the particles together. The composition specifies that the carbide of the resin should weigh between 0.001 to 2% in relation to the metal particles, ensuring optimal bonding and performance with a weld ratio ranging from 10 to 80%. The preferred choice for the resin is furan, which has shown promising results in this application.
