Title: Innovations of Kohei Shimojima in Stretch Molding Technology.
Introduction
Kohei Shimojima is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of stretch molding technology. His innovative approach has led to the development of a unique parison design that enhances the efficiency and strength of hollow vessels.
Latest Patents
Shimojima holds a patent for a parison for stretch molding. This parison comprises a side wall that forms the barrel portion of a hollow vessel during blow molding. It also includes a bottom wall that continues from the side wall and forms the bottom wall of the vessel during the blow molding process. Additionally, the parison features a padding portion that is gradually made thin outward in the radial direction from the central portion of the bottom wall. This design prevents the thickness of the vessel's bottom from being too small after blow molding, while achieving sufficient strength without excessive material usage. Furthermore, it improves the productivity of the parison by increasing its cooling efficiency.
