Abstract
A resin molding machine is capable of preventing molded products from forming resin flash on their surfaces. The resin molding machine includes a press section, a loading section, an unloading section, an accommodating section, a film feeding section, and an air sucking mechanism. By pressing the release film on the surface of the part of the work piece, the release film prevents the melted resin from invading into a gap between the release film and the work piece, so that no resin flash is formed on the surface of the work piece.
