发明名称 Mold preparation method
摘要 A method for the preparation of a mold for use in molding high density information discs includes treating the exposed surfaces of the mold with a solvent to remove any foreign matter therefrom. This step is followed by treating the exposed surfaces of the mold with a cleaning and drying agent to remove any remaining solvent. This is followed by applying a coating of an antistatic agent to the surfaces of the mold. The method is completed by applying a coating of a mold lubricant to the surfaces of the mold.
