“…[7] extracted a robust randomly distributed triangle feature for casting defects detection such as; cracks, blow holes, shrinkage porosities and shrinkage cavities. [8] developed a casting defect analysis system to analyse and reduce defects in investment castings based on Bayesian inference with pre-processing of the input data. [9] proposed an inspection system based on computations of independent quantities on several areas within an image to identify defects on the surface of a metal part produced by a casting process.…”

“…Minimizing the PSE closely related to the gating system is the casting gating system's eventual optimization goal [13,14]. The feeding system is a structure for storing the molten material to compensate for the possible shrinkage in the solidi cation phase during the casting process [15][16][17].…”

“…Metal/alloy is melted in furnace, and then molten metal/alloys is poured into heated shell. Shell is broken (once it is cooled) to get castings [1] [2].…”

“…Investment casting mostly faces quality issue related to occurrence of defects including flash (excess metal dropping perpendicularly on the surfaces), misrun (cavities void of liquid metal in the mold), ceramic inclusion (trapping the particles of the ceramic on the surface or subsurface of castings), slag inclusion (dropping off a combination of metal and investment materials on the surface of castings), shrinkage (tiny cavities similar to a sponge in the last solidifying portion), sweating (dropping metal irregularly on the surfaces of castings), distortion (regarding the shape in original for castings), and crack (The local discontinuity is formed from concentrated stress through solidification). The castings also possess higher set of mechanical properties such as ultimate tensile strength, yield strength, and elongation [1] [2].…”
