Abstract

SE PRODUCE UN ARTICULO MOLDEADO HUECO SUMINISTRANDO UNA RESINA DERRETIDA ENTRE UN PAR DE MOLDES, UNO FIJO Y OTRO MOVIL, ANTES DE QUE EL MOLDE FIJO Y EL MOLDE MOVIL SE CIERREN, INSERTANDO AL MENOS UN PASADOR DE SUMINISTRO DE GAS QUE ESTA PREVISTO SOBRE UNA SUPERFICIE DEL MOLDE FIJO PARA FORMAR UNA PARTE HUECA EN UNA PARTE DE LA RESINA Y SUMINISTRAR GAS PRESURIZADO A TRAVES DE DICHO PASADOR DE SUMINISTRO DE GAS ANTES O A LA VEZ QUE TERMINA EL CIERRE DEL MOLDE, CERRANDO EL MOLDE MOVIL PARA RELLENAR CON LA RESINA UNA CAVIDAD FORMADA POR LOS MOLDES, ABRIENDOSE DESLIZADAMENTE LOS MOLDES MIENTRAS SE PRESURIZA UN GAS EN LA RESINA PARA ENSANCHAR LA PARTE HUECA Y ABRIR EL MOLDE MOVIL PARA EXTRAER EL ARTICULO MOLDEADO HUECO DE LOS MOLDES.
