Abstract

LA CALIDAD BUENA O MALA DE UN PRODUCTO MOLDEADO POR INYECCION SE ESTIMA POR UN METODO QUE COMPRENDE LAS ETAPAS DE MEDIR LA TEMPERATURA T DE UN MOLDE METALICO, DE UNA RESINA EN LA CAVIDAD TAMBOR O INYECTOR DEL MOLDE DE UNA MAQUINA DE MOLDEO POR INYECCION EN UN TIEMPO T TRANSCURRIDO DESPUES DEL COMIENZO DE UNA ETAPA DE MANTENIMIENTO DE LA PRESION DE LA MAQUINA DE MOLDEO POR INYECCION, MEDIDA DE LA PRESION P DE LA RESINA EN LA CAVIDAD TAMBOR O INYECTOR DEL MOLDE EN EL TIEMPO T, CALCULAR UNA FUNCION DEL TIEMPO A = F(T) UTILIZANDO LA TEMPERATURA T Y LA PRESION P, DONDE A REPRESENTA UN PARAMETRO DE CALCULO T/P, P/T, TXP, T + P O T (MAS MENOS) P, Y COMPARAR UNA FUNCION DE TIEMPO DE REFERENCIA AO = F(T) DE UN DISPARO EN EL QUE SE PUEDEN OBTENER PRODUCTOS SATISFACTORIOS, CON UNA FUNCION DE TIEMPO AN = F(T) DE OTRO DISPARO. DE ACUERDO CON ESTE METODO ES POSIBLE ESTIMAR CON EXACTITUD EL VOLUMEN O CONFIGURACION DEL PRODUCTO MOLDEADO.
