TheOobjectiveoofithisoresearch is to know theieffectiof castingitemperatureiwith

new product that is more valuable economical. Casting temperature is an variable
that can effect the result of foundry where if the casting temperature is low, then
there will be a quick freeze before the mold is completely filled. Andoif

namely: 650°C, 700°C, 750°C, and 800°C. The evaporative foundry method uses
