Abstract
SE DESCRIBE UN PROCESO Y APARATO PARA MOLDEO POR INYECCION Y UN ARTICULO DE PLASTICO CON UNA PORCION SALIENTE (72) QUE SE FORMAN UTILIZANDO UNA CAVIDAD DE DERRAMAMIENTO (73). EL PROCESO INCLUYE LOS PASOS DE INYECCION SECUENCIAL DE PLASTICO FLUIDO Y GAS EN UNA CAVIDAD PATRON QUE TIENE UN ESPACIO QUE DEFINE POR LO MENOS UNA PORCION DE LA PARED DEL ARTICULO Y UN CANAL (66) QUE DEFINE UNA PORCION SALIENTE (72) DEL ARTICULO. SE INYECTA INICIALMENTE UNA CANTIDAD DE PLASTICO FLUIDO PARA RELLENAR SUSTANCIALMENTE LA CAVIDAD PATRON. UNA CARGA DE GAS PRESURIZADO SE INYECTA ENTONCES EN EL CANAL (66) DE LA CAVIDAD PATRON PARA DESPLAZAR UNA PORCION DEL PLASTICO TODAVIA FLUIDO EN LA CAVIDAD DE DERRAMAMIENTO (73) QUE ESTA ACOPLADA EN FLUJO AL CANAL (66). PREFERIBLEMENTE, EL GROSOR DE LA PORCION SALIENTE (72) EN SECCION CRUZADA ES POR LO MENOS DOS VECES MAYOR QUE EL GROSOR DE LA PORCION DE LA PARED EN SECCION CRUZADA A LO LARGO LA LONGITUD ENTERA DE LA PORCION SALIENTE (72). TAMBIEN, PREFERIBLEMENTE, EL CANAL (66) SE ADELGAZA A LO LARGO DE SU LONGITUD. LA PORCION SALIENTE PUEDE SER INTERNA O EXTERNA AL ARTICULO.
