Chemicals in laboratory; electron micrographs of sand grains mixed with chemical binders which must be removed to reclaim the pure sand; reclaimed grains free of binder; closeup sand pouring into mold; dissolve to ladle of molten metal and pull back to show the casting process. Animated drawing of sand handling process using heat; animated drawing sand washing process. Long shot molten metal pouring into molds. Animated drawing early mortar mill to prepare sand. CU mortar and pestle reclaiming sand by rubbing. Antique advertisement of Sand Cutter equipment to cut foundry costs. Early still photo workers with sand cutter. Dissolve to modern mechanical shakeout of sand after molding; dissolve to Brown and Sharpe foundry, Providence, RI, one of the first (1960) no-bake foundries in the country, with its huge modern foundry; worker moves large dirty casting by monorail onto turntable which goes into a giant blast cabinet. Dissolve to clean casting coming out of the swing-table cabinet. Foundryman Lou Greenslade explains the process as core knockout and sandblasting are performed simultaneously. Dissolve to TRW Mission Casting Facility, Houston, Texas, using furon-bonded no-bake sand in automatic molding lines. Exterior TRW plant and interiors of the casting lines; flaskless molds transferred to cleaning room; moved to 96" double door swing table blast unit, and 28 cubic foot Tumblast unit.
