Title: Shigeki Ogura: Innovator in Glass Forming Technology

Introduction

Shigeki Ogura is a notable inventor based in Kitakyushu, Japan. He has made significant contributions to the field of glass forming technology, holding two patents that showcase his innovative approach to metal mold design.

Latest Patents

Ogura's latest patents focus on a metal mold for glass forming that eliminates the need for swabbing during the molding process. This innovation allows for a no-swabbing glass forming technique. The alloy used for the mold consists of various elements, including copper (Cu), aluminum (Al), chromium (Cr), nickel (Ni), and rare earth elements. The specific composition includes Cu: 10 to 80%, Al: 4 to 11%, Cr: 3 to 16%, Ni: 2 to 36%, and at least one rare earth element: 0.02 to 2.0%. The mold is designed to be gradually cooled from the solidification initiation temperature to 50°C at a cooling rate of 10°C/min. Additionally, the surface of the mold is either coated with an aluminum-containing coating or roughened to achieve an average roughness of 0.3 to 5 micrometers. A solid lubricating film is also provided in the fitting portion of the mold, or a self-lubricating solid is embedded in that area.
