Abstract:
The aim of this dissertation is to design and analyze the gating system of an aluminum casting piece for anvil casting with an
intention of which dimension shape of the gating system to affect casting piece by using a computer program to simulate Fluid Fraction,
Fill Time, Solidification and Shrinkage Porosity to support this analysis. Meanwhile, the software used for simulating a casting process is
CAST-DESIGNER which is a quick casting design and analysis tool based on upfront design & analysis technology. The scope of this
study is to design the gating system of Anvil casting, of which ADC12 aluminum alloy was investigated in the sand casting, In this case,
the Ingate was designed in three patterns for the following cross sections: rectangle, semi-circle, and trapezoid, with setting the Ingate
area at the ratio of 1 : 2 : 2, including the Runner of the liquid which was 20 and 15 millimeters, respectively. From the study and analysis
of the above results, the shape of the ingate is trapezoidal have a width dimension the height is similar to a square shape, resulting in the
behavior of the fluid fraction in a good direction, this results in an appropriate fill time and also results in solidification time faster and less
shrinkage porosity. The direction to solve the shrinkage porosity problem is to in increase the running, which may result in less shrinkage
porosity or a more complete workpiece.
