Title: Innovations of Koji Nishikawa in Casting Mold Technology

Introduction

Koji Nishikawa is a notable inventor based in Chiba, Japan. He has made significant contributions to the field of casting mold technology, particularly through his innovative patent related to face coat compositions.

Latest Patents

Nishikawa holds a patent for a face coat composition for casting molds and a method for its preparation. This novel composition is designed to improve stability when creating shell-like casting molds for high melting point metals or alloys using the lost-wax mold method. The face coat layer is formed on a wax model using this composition, followed by the application of a backup coat layer. The wax is then removed through melting and calcination, resulting in a durable shell-like mold. The composition includes a rare earth oxide powder as the refractory constituent and a binder that is a synthetic resin in the form of an aqueous emulsion. Additionally, it may contain a small amount of rare earth glass powder to enhance the properties of the face coat layer. This innovative layer is notably resistant to high-temperature melts of reactive metals or alloys, preventing the formation of a reaction-hardened surface layer on the cast body.
