Abstract

La presente invención se refiere a mejoras en método para el moldeo por inyección de artículos de plástico con ayuda de gas, caracterizadas porque comprenden los pasos de: inyectar la placa presurizada de plástico fundido a través de una trayectoria de flujo y hacia el interior de una cavidad de un molde que define el artículo: despresurizar el plástico fundido en la trayectoria de flujo en una cantidad controlada después de la etapa de inyección; introducir una carga de gas presurizado en un nivel predeterminado hacia el plástico fundido para ayudar a moldear el artículo de conformidad con la cavidad que define el artículo; mantener el gas bajo presión mientras que el plástico se solidifica en la cavidad que define el artículo; ventilar el gas presurizado y retirar el artículo del molde.
