Abstract

A mold release agent adhesion state evaluation method is an evaluation method for an adhesion state of a mold release agent used for die casting and adhering to a mold, and includes the steps of: heating the mold; causing the mold release agent to adhere to a surface of the heated mold; acquiring an image data of appearance of the surface of the mold to which the mold release agent adheres; deriving an adhesion state of the mold release agent to the surface of the mold from color quantification information corresponding to the acquired image data of appearance, based on a correlation between previously acquired color quantification information and the adhesion state of the mold release agent; and outputting data concerning the derived adhesion state of the mold release agent.
