Abstract

La presente invención se refiere a un método para fabricar una pieza con una superficie lisa mediante moldeo por compresión de una carga que contiene una resina termoendurecible, consistiendo el método de: a) precalentar la carga a una temperatura de entre aproximadamente 49 grados C y 82 grados C; b) abrir un molde que tiene una matriz superior y una matriz inferior con superficies de moldeo opuestas, que cooperan para definir una cavidad de molde que tiene una forma que corresponde a la forma deseada de la pieza c) colocar la carga precalentada en la superficie de moldear de una de las matrices; d) mover las matrices una hacia la otra hasta una posición parcialmente cerrada, en donde un área que rodea la cavidad del molde se sella y la otra matriz permanece separada de la carga; e) evacuar la cavidad del molde; f) cerrar el molde hasta una posición completamente cerrada de manera lo suficientemente rápida de manera que las matrices compriman la carga para ocasionar que la misma llene la cavidad del, molde antes de que se gelifique la resina; g) mantener las matrices en una posición cerrada durante un período de tiempo suficiente para permitir que la resina se cure; y h) abrir la matrices y extraer la pieza.
