Title: Innovations of Shinichi Okimoto in Metal Injection Molding

Introduction

Shinichi Okimoto is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of metal injection molding, holding two patents that showcase his innovative approaches. His work is primarily associated with The Japan Steel Works, Ltd., where he has developed methods that enhance the efficiency and effectiveness of metal shaping processes.

Latest Patents

One of Okimoto's latest patents is a "Method of coating lubricant in metallic injection machine." This invention involves a movable die that is fastened to a stationary die. The relationship between the contact force of an injection nozzle and the injection hole of the stationary die is investigated. The injection nozzle is brought into press contact with the injection hole by achieving a predetermined closeness, allowing lubricant to be coated under specific pressure conditions. The lubricant is applied as a mist by mixing it with a compressed gas, ensuring optimal performance during the injection process.

Another significant patent is the "Process for producing shaped parts of metals." In this method, a metallic feed in a solid state is introduced into a cylinder barrel of an injection molding machine. The feed is melted through external heat and frictional forces generated by a rotating screw. The process is carefully controlled to maintain the temperature of the metallic feed above its liquidus during injection, allowing for the formation of precisely shaped metal parts.
