Abstract

Un método novedoso para modelar un articulo incluye proveer un molde, con una abertura de un tamaño predeterminado de tal manera que, debido a la diferencia en las viscosidades, los gases que se van a dejar salir del molde puedan pasar fácilmente a través de la abertura, mientras que el material que se va a moldear no pueda pasar rápidamente através de la abertura. De hecho, la abertura se diseña de tal manera que el material que se va a moldear, que entre en la abertura, no salga por el extremo de la abertura. En la modalidad que más se prefiere, la abertura tiene la forma de una ranura parecida a una cinta delgada, de manera que el material que se va a moldear, que entra en la abertura, forme una cinta delgada de material extruído que no necesite ser retirado antes de que se aplique la cubierta de acabado al artículo moldeado.
