Latest Patents

One of Teraoka's latest patents is a method and apparatus for forming thermoplastic resin foam. This invention involves the plasticizing of a thermoplastic resin material by rotatably driving a screw. The process includes injecting an inert gas into a screw cylinder to permeate the melted resin. The melted resin is then injected into a mold by driving the screw in the direction of injection. The inert gas used has a pressure equal to or greater than a supercritical pressure or is under a supercritical state. Electric servomotors are employed to drive the screw, and brakes are applied to prevent the screw from retreating after the plasticizing step is completed. This innovative method allows for effective foaming inside the screw cylinder.
