摘要： A microstructure is formed in a viscous glass or plastic substrate by pressing a structured surface of a forming tool corresponding to a negative of the microstructure to be produced in the viscous glass or plastic substrate. After the microstructure has been formed, the forming tool is removed from the surface. In order to help form the microstructure and remove the forming tool from the substrate the forming tool has an at least partially porous base body (1) and an operative layer (2) structured with a negative structure consisting of grooves (11) extending to the porous base body (1). The forming of the microstructure in the substrate is assisted by applying suction to the porous base body (1) so that the grooves (11) fill more easily and completely with melted glass or plastic material. The removal of the forming tool after forming the microstructure is assisted by applying an overpressure to the porous body to help release the solidified glass or plastic material from the forming tool.

摘要： A molding die has a shell having a penetration hole, a lower pattern installed in the lower opening of the shell, and an upper pattern slidably disposed from the upper opening of the shell. The shell includes an outer shell and an inner shell disposed inside of the outer shell. The inner shell is includes plural split shells. The inner shell can be separated from the outer shell. The inner shell, lower pattern, and upper pattern form a cavity. As a result, if the molded product sticks to the inner circumference of the shell, the molded product can be easily taken out of the molding die by disassembling the shell. Further, a molded product having an excellent dimensional precision can be manufactured.
