In this process, granular refractory sand is coated with a mixture of bentonite clay, water and, in some cases, other additives (Fig. 1). The additives help to harden and hold the mold shape to withstand the pres-sures of the molten metal. The green sand mixture is compacted by hand or through mechanical force around a pattern to create a mold. The me-chanical force can be induced by slinging, jolting, squeezing or by impact/impulse.
