Title: Masafumi Nakamura: Innovator in Polyurethane Foam Technology
Introduction
Masafumi Nakamura is a notable inventor based in Suita, Japan. He has made significant contributions to the field of polyurethane foam technology, holding 2 patents that showcase his innovative methods in producing molded articles.
Latest Patents
Nakamura's latest patents include a production method for polyurethane foam molded articles. This invention provides a method for producing a polyurethane foam molded article from a polyisocyanate compound, a polyol mixture containing polyol, a catalyst, a crosslinking agent, and a blowing agent. The method involves continuously injecting the polyisocyanate compound, the polyol mixture, and the blowing agent into a mold using a specialized molding machine. The timing of the injection of the blowing agent is strategically delayed to enhance the properties of the final product. This innovative approach allows for the selective formation of skin or high-density portions on the molded article, enabling variations in the proportions of the skin, high-density portion, and foamed core.
Another patent by Nakamura details a method of producing a polyurethane molded article using a single molding machine that can distinctly provide polyisocyanate components and two kinds of polyol components. This method also allows for the selective formation of high-density portions, further demonstrating Nakamura's expertise in this area.
