More Information
Summary:A method for cleaning or treating a mold includes form a cleaning charge or a release-agent charge, placing the charge in a mold cavity and applying heat and pressure to the charge, thereby conforming the charge to the mold cavity and forming a mock part, and then ejecting and discarding the mock part. During processing of the cleaning charge, contaminants adhering to the walls of the mold cavity from previous molding runs are incorporated into the mock part. During processing of the release-agent charge, release agent is transferred from the charge to the surface of the mold cavity.
