Title: Isao Okamura: Innovator in Injection Molding Technology
Introduction
Isao Okamura is a notable inventor based in Sagamihara, Japan. He has made significant contributions to the field of injection molding technology, holding a total of 3 patents. His work focuses on enhancing the efficiency and functionality of injection molding apparatuses.
Latest Patents
One of Okamura's latest patents is a metering device for a nozzle of a hot runner injection molding apparatus. This innovative device includes an injection piston that is slidable within a nozzle featuring a movable valve gate pin. The injection piston can move from a retracted position to an extended position, allowing it to force melt towards a mold cavity. A valve located at the forward end of the piston selectively blocks communication between a recess in the piston and the melt chamber of the nozzle. As the injection piston moves to the extended position, the valve closes, ensuring that a predetermined volume of melt is forced into the mold cavity when the valve gate pin opens the mold gate.
Another patent by Okamura is similar in nature, focusing on the metering device for a nozzle of an injection molding apparatus. This patent also describes the functionality of the injection piston and valve system, emphasizing the importance of precise control in the injection molding process.
