Abstract

SE HA DESCUBIERTO QUE CUANDO LAS PRE-FORMACIONES EN CAPAS SE ESTAN MOLDEANDO POR INYECCION, UTILIZANDO AL MENOS DOS MATERIALES, ES POSIBLE MANTENER LA MISMA PENDIENTE HORIZONTAL Y VERTICAL DE CAVIDADES ADYACENTES, COMO ES POSIBLE CUANDO CADA HUECO DE MOLDE SE ESTA LLENANDO CON UN UNICO MATERIAL. MAS ESPECIALMENTE, SE HA DESCUBIERTO QUE CUANDO EL PORCENTAJE DEL MATERIAL QUE SE VA A INYECTAR EN UNA CAVIDAD DE UN MOLDE ES RELATIVAMENTE ALTO, ES POSIBLE UTILIZAR UN UNICO CRISOL DE MEDICION (18) PARA CUATRO HUECOS DE MOLDES ADYACENTES (10). POR OTRA PARTE, SI UNO DE LOS MATERIALES QUE SE VAN A INYECTAR DENTRO DE UNA CAVIDAD DE MOLDE CONSTITUYE UN PORCENTAJE RELATIVAMENTE BAJO DEL VOLUMEN DE UNA CAVIDAD DE MOLDE, SE HA DESCUBIERTO QUE UN PEQUEÑO CRISOL DE MEDICION (40) DEBE FACILITARSE PARA CADA UNO DE LOS HUECOS DEL MOLDE DE CUATRO HUECOS (10). MAS ESPECIALMENTE, CON ESTA COMBINACION, ES POSIBLE MANTENER LA PENDIENTE DEL MOLDE DE MATERIAL UNICO Y DE ESTA FORMA MANTENER EL PEQUEÑO TAMAÑO DE LOS SISTEMAS DE INYECCION EXISTENTES, EN OPOSICION A UN INCREMENTO DE LA PENDIENTE DE LOS HUECOS DEL MOLDE QUE INCREMENTARIAN EL TAMAÑO DE LA ESTRUCTURA DEL MOLDE.
