| 摘要 |
The present invention provides a mold ( 10 ) for press molding articles, such as optical lenses. The mold includes a molding base ( 11 ) and a surface film ( 12 ). The molding base is made by a sintered composite of carbon nano fibers ( 13 ) and metal nano particles ( 14 ). The nano metal particles are selected from a group consisting of platinum, platinum-iridium alloy, rhenium and rhenium-iridium alloy. The surface film is formed on the molding base by a sputtering deposition method. A method for manufacturing the above-described mold is also provided. The mold has higher mechanical strength and better toughness than conventional molds that are made by metal alloy or metal ceramics.
