Latest Patents

One of Hideo Ohyabu's latest patents is a method and apparatus for forming thermoplastic resin foam. This invention involves the plasticization of a thermoplastic resin material through the rotatable driving of a screw. The process includes injecting an inert gas into a screw cylinder to permeate the melted resin, followed by injecting the melted resin into a mold. The inert gas is maintained at a pressure equal to or greater than a supercritical pressure, or it is kept under a supercritical state. Electric servomotors are utilized to drive the screw, and brakes are applied to prevent the screw from retreating after the plasticization step. This innovative method allows for effective foaming inside the screw cylinder, enhancing the production of thermoplastic resin foams.
