ROBAR Capabilities Foundry SAND Patterns • Molds • Melting • Core • Sand • Heat Treat • Coating • Light Forging • Rubber Gaskets  We operate a fully mechanized, Silica Green Sand molding system with emission controls and sand-testing facilities. The sand is not actually green. It is a foundry name for industrial casting sand that is basically silica, with clay, a little water, and organic binders in it. The silica sand starts out white, but the binders (ordinary wood and cereal flour) carbonize or turn black when exposed to molten metal during the pouring process, which t gives the sand its distinct color. The molding sand is recycled through the Sand Reclamation System. The sand is cleaned and refreshed in this process. Mixing and wetting of sand occurs in our Beardsley & Piper 85-B Speedmullor. It can deliver up to 2,000 pounds of prepared sand in a minute. Current production rates require about 1,600 pounds per minute, which is equal to 3800 wheelbarrow loads per day. Molding sand is recycled and reused. In a typical day, the whole system is rotated about once per shift (twice per shift before the new Sand Reclamation System was installed). The sand grains are worn down in the process so ROBAR currently purchases about 1,200 tons of new sand each year.
