Abstract
The present invention relates to a method of manufacturing a metal mold for replicating a component having a predetermined three-dimensional shape, the manufacturing method comprising: (a) fabricating a glass-based mold by using a moldable nanocomposite comprising an organic binder and glass particles dispersed therein, the glass-based mold having the predetermined three-dimensional shape; and (b) replicating the glass-based mold obtained in step (a) by melting a metal inside the glass-based mold or by melting a metal outside the glass-based mold and pouring it onto or into the glass-based mold, followed by cooling, or by pressing the glass-based mold into a malleable metal substrate, thereby obtaining the metal mold for replicating the component, the metal mold having the predetermined three-dimensional shape inverted. Further, the present invention relates to a method of replicating a component having a predetermined three-dimensional shape, wherein the metal mold obtained by the manufacturing method is used for replicating the component, wherein the glass particles of the moldable nanocomposite comprise a first type of glass particles having a diameter in the range from 5 nm to 500 nm.
