Ceramic screw handles highly filled materials.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 shank (shangk) 1. leg (1). 2. crus ( 2). shank n. The part of the human leg between the knee and ankle. , this is said to be the first screw to use ceramics as more than a thin surface coating Surface coating A substance applied to other materials to change the surface properties, such as color, gloss, resistance to wear or chemical attack, or permeability, without changing the bulk properties. . The sleeve segments are machined from ceramic in a "green," unsintered state. This new development from Battenfeld Injection Molding injection molding n. A manufacturing process for forming objects, as of plastic or metal, by heating the molding material to a fluid state and injecting it into a mold. 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 ECT electroconvulsive therapy. ECT abbr. electroconvulsive therapy ECT Electroconvulsive therapy sometimes is used to treat depression or mania when pharmaceutical treatment fails. Extrusion for Ceramic Technology in Muhlacker, is developing extruders with ceramic screws and barrels.
