This study is a preliminary research about the casting of gray cast iron by using ductile cast iron mold that has been preheated. Preheating is done to unify the hardness in gray cast iron. The mold heating was carried out at temperatures of 100, 200, 300 and 400°C. Meanwhile, the hardness testing was carried out by using Rockwell hardness test. The results showed that the higher the mold heating, the more the distribution of gray cast iron hardness. © 2006-2016 Asian Research Publishing Network (ARPN).
