Title: Kenichi Yamamura - Innovator in Die-Casting Technology
Introduction
Kenichi Yamamura is an inventor based in Kikugawa-shi, Japan. He has made significant contributions to the field of die-casting technology. His innovative approach focuses on improving the efficiency and effectiveness of die-casting processes.
Latest Patent Applications
Kenichi Yamamura has filed a patent application for a "DIE-CAST MANUFACTURING METHOD AND DIE-CAST MANUFACTURING APPARATUS, AND PRESSURIZATION MEANS." This application describes a die-casting method and apparatus that effectively prevent the backward flow of molten metal. It also enables additional pressurization to a product injected within a cavity when pressurization of a runner is performed after molten metal injection by a plunger. The invention includes an injecting portion with first pressurization means that injects molten metal into a die-casting metallic mold, second pressurization means that pressurizes a runner communicated with the cavity, and an orifice formed on a surface corresponding to a rising runner portion directly connected to the cavity in the runner. The second pressurization means performs pressurization through the runner after the first pressurization means injects molten metal, while preventing the molten metal from flowing backward with the orifice in a pressurization passage.
Conclusion
Kenichi Yamamura's work in die-casting technology showcases his innovative spirit and dedication to improving manufacturing processes. His patent application reflects a significant advancement in the field, highlighting his potential impact on future developments in die-casting methods.
