Evaluasi Efisensi Riser Untuk Bentuk Riser Samping yang Berbeda Menggunakan Metode Simulasi Casting

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