Abstract: When substantial numbers of parts are rejected, deliveries are delayed, machining time and costs are lost, and the product cost and lead time is increased. The American metalcasting consortium (AMC), which is supported by the defense logistics agency (DLA), the American Foundry Society (AFS), and selected foundries producing military castings rejects. Bulk density measurements and tests to measure mold binder content were performed on samples from fluidity spirals molds (70% silica/ 30% zircon), 100% zircon ring molds, and 70% silica / 30% zircon ring molds.
