Abstract
SE PROPONE UN PROCEDIMIENTO PARA LA FUNDICION INYECTADA DE PIEZAS DE FORMA DE CUERPO HUECO DE MATERIALES TERMOPLASTICOS. PRIMERO SE PRENSA LA CANTIDAD SUFICIENTE DEL MATERIAL FUNDIBLE EN LA FORMA DE INYECCION. A CONTINUACION SE PRENSA UN MEDIO FLUIDO, SOBRE TODO GAS, EN LA FORMA DE INYECCION, QUE DISTINGUE LA MASA DE PLASTICO DE FORMA UNIFORME SOBRE LA SUPERFICIE DE LA ZONA DE FORMA HUECA, FORMANDOSE ASI EL CUERPO HUECO. COMO SIGUIENTE PASO, EL CUERPO HUECO SUJETADO BAJO LA PRESION SE REFRIGERA EN LA FORMA DE INYECCION. ENTONCES SE DEJA SALIR LA PRESION DEL CUERPO HUECO Y LA PIEZA DE FORMA DE INYECCION. ES IMPORTANTE QUE LA PRESION DEL MEDIO PUEDA VARIARSE TEMPORALMENTE DENTRO DE LA FORMA DE INYECCION, SEGUN UN PERFIL DE PRESION DETERMINADO PARA CADA PIEZA DE FORMA.
