Title: Hiroki Katagiri: Innovator in Hollow Body Molding Technology
Introduction
Hiroki Katagiri is a prominent inventor based in Ota, Japan. He has made significant contributions to the field of molding technology, particularly in the development of hollow body molding devices. With a total of 4 patents to his name, Katagiri continues to push the boundaries of innovation in his industry.
Latest Patents
One of Katagiri's latest inventions is a hollow body molding device. This device features a unique design where molten resin is injected into a main cavity. After the injection, fluid is pressure-injected through a pressure port, allowing a floating core to move towards the outlet side. As the floating core moves, the molten resin is extruded from the outlet, resulting in the formation of a hollow molded body. The device also includes a floating core storage portion connected to the main cavity, which stores the floating core moved by the pressurized fluid. Additionally, an auxiliary cavity is designed to store molten resin discharged from both the main cavity and the floating core storage portion. The communication passages between these components are specified by their inlet cross-sectional area.
Another notable patent is a method of manufacturing a pipe with a branch. This method involves injecting molten resin into a main cavity equipped with a pressure port and a floating core. After the resin injection, a pressurized fluid is introduced through the pressure port, moving the floating core towards the first outlet. Simultaneously, the molten resin is extruded from the first outlet to create a main pipe hollow. Once the main pipe hollow reaches the branch cavity, the second outlet is opened, allowing the pressurized fluid to extrude molten resin from the second outlet to form the branch pipe hollow.
