“…Untuk antisipasi shrinkage tersebut ditambahkan riser yang berfungsi mengompensasi cairan untuk mengisi rongga susut yang terbentuk saat proses solidifikasi. Riser bertindak sebagai reservoir logam cair dan sumber suplai cairan untuk menghilangkan shrinkage [3]. Desain riser yang optimal akan menghasilkan komponen casting yang bebas dari shrinkage.…”

“…Beberapa penelitian lain menggunakan pendekatan simulasi CAE untuk mengukur tingkat efisiensi dan efektifitas bentuk riser. Shuvo dan Manogharan (2021) melakukan penelitian pengaruh tiga bentuk riser berbeda; ellipsoid, spherical, dan silindris untuk aplikasi pada riser atas [3]. Penelitian lain yang dilakukan oleh Malik dkk (2020) membandingkan bentuk riser taper silindris dan silindris untuk aplikasi pada riser atas dengan riser juga diposisikan sebagai sprue [10].…”

As the solidification reaches the hot spot area, no molten metal remains and shrinkage is formed. To anticipate the shrinkage, a riser is added to the casting system. An optimal riser design would produce free shrinkage components. One of the factors that affect riser efficiency is the riser shape. This study aims to find the most efficient side riser shape by using simulation software. The riser shape of tubes, tubes with a half sphere on top, hemispheres, conical tubes, tubes with an oval cross-section, and cubes are used in this experiment, with the volume of all risers kept constant. The most efficient shape of the riser is the tube. The tube riser produces a larger modulus. The tube riser generated directional solidification. The same pattern can be seen in the niyama criteria and solidification temperature, where the tube riser has a more continuous pattern compared to other riser shapes.

“…Regarding the geometry of the riser, there are authors such as M. Shuvo et al [10] who advocate the use of new geometric shapes for the design of the riser. However, due to the theoretical approach of this paper, the ideal is to select one that has a simple geometry and causes its cooling modulus to be maximum.…”

In Engineering Schools, labs for teaching forming processes by means of material conservation methods are generally equipped with the appropriate equipment and tools to exemplify the theory received in class. However, the use of simulation techniques to complement the formation is not usually widely extended, since their learning is not usually trivial.One of the material conservation forming processes is sand casting. This process is of great educational significance, since the theory that defines it sets the basis for understanding other related moulding processes. In this context, the use of simulations of the moulding process allows the visualization of practical examples, helping to explain more clearly the theoretical information explained in class.Therefore, in this research a simulation assisted analysis has been developed using the Inspire Cast by Altair software, of teaching parts made in sand casting. First of all, students have been shown by means of simulations, the defects that can be originated in a part manufactured by sand casting. The study has been carried out by redesigning the risers involved in the distribution system of the process, by means of the Chvorinov's rule.Finally, a series of conclusions have been achieved, among which the following one stands out: if the functional performance of the part manufactured by sand casting is to be taken into account, the cooling modulus criterion must be selected for the design of the riser. Although, in principle, the material required for moulding is much larger, the defects generated in the part will be considerably reduced.
