The Rocket scored 117 in the second frame to hit back after losing the opener and although Higgins took the fifth frame to edge back to 3-2, it was plain sailing for the five-time world champion as he set up the showpiece match with Judd Trump without conceding again.
Trump had earlier secured his place in Saturday's final with a 6-3 victory over fellow Brit, Jack Lisowski.
