Corrosionpedia explains Shrinkage Metals undergo contraction when solidifying and cooling, because the specific volume is larger in the liquid state than in the solid state for standard casting metals. In metalworking and jewellery making, casting is a process in which a liquid metal is somehow delivered into a mold (usually by a crucible) that contains a hollow shape (i.e., a 3-dimensional negative image) of the intended shape.The metal is poured into the mold through a hollow channel called a sprue.The metal and mold are then cooled, and the metal part (the casting) is extracted.
