Di Nenno and Stupaczuk had to come back from behind, conceding the first set 4-6, but steamrolled Chingotto and Navarro after as they swept the second set 6-0 and won the third 6-1.
It is the fifth final in the last six tournaments for Di Nenno and 'Stupa', who will fight to win back-to-back titles for the first time as they take on Arturo Coello and Agustin Tapia in a final for the fourth time.
Chingotto and Navarro were playing their second semi-final together since forming, but still await their first final appearance.
