Pengaruh Variasi Kecepatan Putar, Temperatur Cetakan Dan Temperatur Tuang Terhadap Fluiditas Pengecoran Aluminium Kaleng Minuman Menggunakan Metode Qudong

Andry Sutanto, Warman Fatra, Zuchra Helwani


Castability is a measur of the ability of an alloy to be formed according to the desired shape using a casting process, which is limited by fluidity. Qudong method 1999, used in this research with varying pouring temperature; 650oC, 700oC, 750oC, mold temperature; 100oC, 200oC, 300oC and cavity thickness; 0.5 mm, 1.0 mm, 1.5 mm, 2.0 mm, 2.5 mm, 3.0 mm, 3.5 mm, 4.0 mm. As an effort to increasing castability, this research giving a rotation to look the effect of variation mold temperature, pouring temperature and rotation. Fluidity increased with the increasing pouring temperature, mold temperatur and rotation. Fluidity increases with cavity thickness, maximum fluidity achieved at pouring temperature 750oC, mold temperature 300oC and rotation 1500rpm at 2.0-4.0 mm with a length of 120 mm and minimum fluidity can be filled with molten metal is at 0.5 mm with a length of 15.5 mm.
Keywords : fluidity, molten aluminum cans, pour temperature, mold temperature, rotation.
