Abstract

PROCEDIMIENTO PARA LA OBTENCION DE UN CUERPO HUECO DE DOS CAPAS.CONSISTE EN: A) MOLDEAR POR INYECCION UN PARISON INTERIOR UTILIZANDO RESINA SINTETICA DE BAJA TEMPERATURA DE TRABAJO, EXTRAYENDO A CONTINUACION DICHO PARISON INTERIOR QUE ES DEPOSITADO EN UN NUEVO MOLDE, ENTRE CUYA PARED Y LA SUPERFICIE EXTERNA DE TAL PARISON INTERIOR SE DEFINE UNA SEPARACION SOBRE LA QUE SE INYECTA RESINA SINTETICA DE ELEVADA TEMPERATURA DE TRABAJO DETERMINANDOSE EL MOLDEO DE UN SEGUNDO PARISON EXTERIOR. DURANTE EL MOLDEO DEL PARISON EXTERIOR SE PROCEDE A ENFRIAR LA SUPERFICIE EXTERNADEL PARISON INTERIOR HASTA LA TEMPERATURA MAS BAJA POSIBLE, OBTENIENDOSE UN PARISON DE DOS CAPAS QUE ES INMEDIATAMENTE PASADO A UN MOLDE DE ACABADO EN EL QUE SE ESTIRA LONGITUDINALMENTE Y SE MOLDEA POR SOPLADO PARA OBTENER EL CUERPO HUECO DEFINITIVO DE DOS CAPAS.
