Title: Hiroyoshi Hiratsuka: Innovator in Sintered Body Manufacturing

Introduction

Hiroyoshi Hiratsuka is a notable inventor based in Sendai, Japan. He has made significant contributions to the field of manufacturing, particularly in the process of creating sintered bodies. His innovative approach has led to the development of a unique patent that addresses common challenges in the industry.

Latest Patents

Hiratsuka holds a patent for a "Process for manufacturing sintered bodies." This process utilizes an organic binder that includes both water-soluble and water-insoluble thermoplastic organic polymers. The water-soluble polymer is extracted through a debinding treatment, which involves the contact of a plastic molded part, such as an injection molded part, with water. This method effectively prevents cracks in the molded part. By reducing the amount of organic binder, the process minimizes the risk of softening and deformation during heating and sintering. Notably, when polyethylene oxide is used as the water-soluble binder, thermal debinding can be eliminated, significantly reducing the debinding time.
