A ceramic screw with exceptional corrosion and wear resistance for molding highly filled polymers may soon be introduced for commercial use.

A ceramic screw with exceptional corrosion and wear resistance for molding highly filled polymers may soon be introduced for commercial use. Consisting of a segmented ceramic sleeve over a metal shank, this is said to be the first screw to use ceramics as more than a thin surface coating. The sleeve segments are machined from ceramic in a "green," unsintered state. This new development from Battenfeld Injection Molding in Germany (U.S. office in Elgin, Ill.), emerged from a four-year project by Battenfeld and five German partners to develop a screw using industrial ceramics that would outperform existing materials. One of these partners, ECT Extrusion for Ceramic Technology in Muhlacker, is developing extruders with ceramic screws and barrels. Battenfeld: (847) 531-0015/PTDirect: 856TV .
