Abstract
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.
Claims11
A mold comprising:
- a molding base comprising a sintered composite of carbon nano fibers and metal nano particles;
- and
- a surface film formed on the molding base.
A mold manufacturing method comprising:
- mixing carbon nano fibers with metal nano particles so that they are all homogeneously distributed;
- sintering the carbon nano fibers and the metal nano particles by a hot pressing method, thereby forming a molding base;
- carving an optical pattern on a surface of the molding base;
- and
- forming a film on the molding base.
