processes for general shapes

Machine Molding - method is 'automated and therefore faster than bench molding, but the casting process is essentially similar. Molding machines sling, ram, jolt or squeeze sand onto patters, which in this case may consist of several parts arranged on a moldboard. Dimensional control, surface finish and product consistency are better than those achievable with bench molding. Favorable costs can be realized from as few as several dozen castings. Machine-molded sand casting is therefore the most versatile process in terms of production volume.
