Abstract

SE PRESENTA UN METODO PARA MANUFACTURAR UNA AGUJA INTEGRAL EN UNA SOLA PIEZA. EL METODO COMPRENDE EL SUMINISTRO DE UNA RESINA POLIMERICA EN EL INTERIOR DE UNA CAVIDAD DE MOLDEADO Y LA INYECCION DE UN FLUIDO BAJO PRESION AL INTERIOR DE AL MENOS UNA PARTE DE LA CAVIDAD PARA EXPULSAR DE LA MISMA LA REGION CENTRAL DE LA RESINA POLIMERICA. ESTO CREA UN ANILLO DE RESINA POLIMERICA QUE TIENE UN ORIFICIO A TRAVES DEL MISMO, EL ANILLO DE RESINA POLIMERICA FORMA LA CANULA DE LA AGUJA, EL CILINDRO DE MONTAJE ES PROVISTO POR LA PARTE RESTANTE DE LA CAVIDAD.
