The directional solidification which is not toward to riser causes the shrinkage defect. This defect can
be predicted by investigating the temperature distribution in riser or casting products. The goal of this
research is to examine the temperature distribution using Finite Element Software (ANSYS) and then an
ad hoc experiment has been performed to verify the result of the simulation, especially the existences cf
shrinkage
The simulation is carried out by sand casting process using pure aluminum. This research uses
enthalpy method to examine the distribution of temperature. The properties of melted metal that being
used for the simulation are enthalpy H(T) and thermal conductivity k(T). For experiment, the sand casting
process uses pure aluminum and eutectic aluminum. The eutectic aluminum castings is used to support
the pure aluminum castings.
The result of the simulation hypothesis against shrinkage defect is appropriate with the experiment result.
