Green Sand Casting 01

Green sand-mold casting involves mixing sand with a suitable clay binder (usually a bentonite clay) and other additives, and packing the sand mixture tightly around a pattern that is constructed from the part design, but the pattern is not an exact replica of the part since various dimensional allowances must be made to accommodate certain physical effects. After extracting the pattern from the sand mold, a cavity is left behind that corresponds to the shape of the pattern. Next, molten metal is poured into this cavity and solidifies into a cast replica of the desired part. After the casting cools, the sand is readily removed from the casting and may be reclaimed for further use.
