Abstract

La presente invención se refiere a método de moldeo, por compresión de piezas, cuyo método comprende; colocar material moldeable en el troquel inferior de un aparato de moldeo a presión: utilizar un ariete para llevar el troquel superior y el anillo sellador a una posición en la que el sellado al vacío se hace rodeando una cavidad del molde definida por los troqueles superior e inferior, crear un vacío en la cavidad del molde, formar la pieza y retirar el anillo sellador para romper el sellado al vacío que rodea, la cavidad del molde sin utilizar el ariete, para que los dos troqueles puedan abrirse prontamente después que se ha roto el sellado al vacío.
