Containerless processing technologies at the Jet Propulsion Laboratory

Residual gravity in space processing would entail contact of the material with its container and hence prevent it from retaining its natural shape, in case of molten metal, and risk its contamination.

Summary:Residual gravity in space processing would entail contact of the material with its container and hence prevent it from retaining its natural shape, in case of molten metal, and risk its contamination. JPL developed systems for avoiding such contacts, and experimented them in the laboratory. One is based on the properties of acoustics, the specimen being held at the nodes of resonant waves. The other ensures levitation by electrostatic means. These systems are defined and discussed, and the first favorable results presented.
