Title: Innovations in Injection Molding by Ryohei Hazawa

Introduction

Ryohei Hazawa, a prominent inventor based in Tokyo, Japan, has made significant contributions to the field of thermoplastic injection molding. With a total of two patents to his name, Hazawa's innovative approaches aim to enhance the efficiency and quality of thermoplastic manufacturing processes.

Latest Patents

Hazawa's latest patents focus on methods to produce thermoplastic parts free from sink marks and voids. His first patent details a mold designed for injection molding a thermoplastic part free from sink marks. This involves the use of a void inducing member placed within the cavity of the mold, which accommodates heavy sections of the part. By applying gas pressure through a gas passageway to the tip of the void inducing member, a void nucleus is created in the resin adjacent to its tip. This void nucleus evolves into a void due to the shrinking forces of the resin as it cools.

Additionally, Hazawa has developed an injection molding method that outlines similar steps, reinforcing the idea of preemptively managing voids during the injection process. These inventions significantly improve the aesthetic and structural integrity of thermoplastic parts, making them highly valuable in manufacturing.
