WebSome common casting defects include surface defects, inclusion defects, and cooling defects. Destructive testing. In every production run, the foundry will choose a few samples and submit them to destructive testing. The casting is cut, and the properties of the metal inspected closely. The tester will look for inclusions, porosity, and shrinkage. Pouring metal defects include misruns, cold shuts, and inclusions. A misrun occurs when the liquid metal does not completely fill the mould cavity, leaving an unfilled portion. Cold shuts occur when two fronts of liquid metal do not fuse properly in the mould cavity, leaving a weak spot. Both are caused by either a lack of fluidity in the molten metal or cross-sections that are too narrow. The fluidity can be increased by changing the chemical composition of the metal or by increasin…
