A manufacturing method for metal roller set of skate includes following steps: A. Cut the aluminum alloy with n cross section into roller set prototype; B. Put the prototype in hot furnace and heat in 280 deg.C-400 deg.C for 3 to 10 hr. to soft the metal structure then take it out to cool; C. Put the cooling prototype on bottom mold of tri-direction forging machine, then squeeze the top surface & two sides of prototype by top mold & two sides mold to form the roller set product; D. Put the roller set product in furnace and heat from low temp. to 450 deg.C, then take it out and quench in water, then put it in 280 deg.C furnace for 10 hr. and take it out to finish the hardness treatment.
