Green Sand Casting

The standard sand casting procedure that we implement for our bronze and aluminum castings is the green sand molding method. With this method the sand, which is mixed with a binder, is packed around the pattern to produce the mold. This is done by hand with pneumatic tools or with our automated sand machine known as a hunter. The patterns are removed from the mold leaving a cavity that will later provide the parts geometry. If the part being cast needs to be hollow or has areas of undercut, a core is used to provide the internal features. One of the great things about the green sand method is that no baking or chemical treatment is required to get the mold to its final state so the cost and time between a finished pattern and a finished part is greatly diminished.
