SAND PATTERNS FOR COMMERCIAL FOUNDRIES
The art founder is rarely required to produce more than half a dozen or so casts from an single pattern design. This typically short production run means that the ‘bespoke’ sand piece moulding technique used by the average art founder, is quite in keeping with the overall demands of their typical workload. For the commercial founder, with orders for possibly hundreds or even thousands of cast copies, forming each individual sand piece by hand would be unthinkable - or at least prohibitively expensive and time consuming. The distinctive environment of the commercial foundry has led to the evolution of sand moulding techniques which bear little more than a passing resemblance to the relatively archaic (if highly adaptable), methods of sand piece moulding employed by the art founder. This difference in approach inevitably has some considerable impact on the preparations made to a master pattern before it’s submission to a commercial sand casting operation.
