Check out NASA Glenn Research Center’s large-scale, 5 kg planar flow caster as it cools a vat of molten metallic alloy, producing a magnetic ribbon that spouts into a collection bin. The caster has the ability to produce a magnetized ribbon that measures up to a mile long and 50 mm wide to support NASA’s hybrid electric aircraft propulsion and power management work. The process is a thing of beauty.
